Lab-grown, natural and moissanite: 6,123 Questions Buyers Asked (page 8 of 31)

Get it evaluated and insured, then take it to a local jeweler to verify the stone and design a custom setting.

Estimates ran about $30-100 in labor plus a replacement stone, with tiny diamonds wholesaling around $40 a carat and lab-grown melee around $100 a carat, though a regular jeweler charged one person's mother almost $100 for a similar small stone versus $5 at a pawn shop.

The buyer describes years of repeat custom orders through the same rep, calling service responsive and prices good, across bezel rings, a lab diamond pear necklace, colored gemstone rings, and a family constellation necklace.

Opinions are split: many say origin doesn't matter as long as the ring is pretty and affordable, and note jewelers themselves often can't tell lab from natural by eye, while some women say they'd still prefer natural for resale value or family expectations.

Buyers agree lab diamonds keep almost none of their price on resale, while natural diamonds might resell for roughly half of what was paid, and either way an engagement ring is described as a poor investment overall.

Examples here range from about $1,000 for a modest moissanite or lab ring up to around $4,500 for a larger custom moissanite stone, versus natural stones and name-brand rings running into the tens of thousands.

Several buyers suggest simply not disclosing whether the stone is lab or natural, since family can't tell by looking and the choice belongs to the couple.

Buyers say lab diamonds are real diamonds with more depth, crisper sparkle and better durability than CZ, which clouds over time, or moissanite, which some describe as rainbow-flashy or plasticky, and that falling lab diamond prices have made the choice easier.

Buyers describe moissanite as throwing more rainbow, disco-ball-style flashes with double refraction, while diamonds show a crisper, more colorless glitter with greater depth, and a couple note round moissanite reads closer to diamond than larger oval cuts.

No: buyers warned that an appraisal from a stone's own seller is unreliable, that lab reports get faked often, and that a gemologist's credentials can be checked against professional registers like Gem-A to see if they are really a paid member.

INSIGHT: buyers said to look up the gemologist's name in professional registers such as Gem-A or the Canadian register to confirm paid fellow membership, and to check the lab itself against a published list of credible gem labs worldwide.

No — buyers who made similar custom pieces paid well under that: one paid under $600 for just the setting (about $3k total with a matching band), another paid less than half of a $10k quote elsewhere, and a vendor quoted about $3,000 to replicate the design in India with lab stones.

Buyers recommend reaching recommended vendors like Tianyu through WhatsApp (found via the an online group vendor wiki), paying with PayPal for buyer protection, and asking for a small CAD design fee, around $50, before committing to full production.

One buyer paid about $100 to have her lab diamond, bought separately online, set locally after having the setting itself made overseas.

Opinions split: one buyer said the price looked right, but others called it suspiciously cheap for that size, warning that a very large stone priced that low often hides a poor cut or other issues the 4Cs alone don't capture.

INSIGHT: A buyer described ordering a 3.5ct VS1 emerald-cut lab diamond advertised as 'super ideal' cut for $999 shipped, only to find the cut wasn't actually ideal once received and having to return it.

Yes, buyers describe silver or moissanite rings for as little as $8 to $75 on Amazon, AliExpress and Etsy, and one bought an exact replica of her real ring on Amazon for $9.99.

There's no set figure, but buyers commonly suggest somewhere between $20 and $500 as a reasonable minimum to show effort, with several saying a $50 to $100 cz or moissanite ring would be enough.

One buyer said her $3,000 high-end moissanite ring would have cost roughly $90,000 for a similarly sized, similarly graded diamond.

Most buyers say yes, it's overpriced, estimating a fair price for a comparable 2.5-3 carat lab stone at roughly $1,000 to $2,500, though a few noted the rare antique elongated-cushion cut in the post commands a real premium over a standard cushion.

Buyers explain that physical stores carry overhead costs, while online sellers, especially India- and Asia-based ones with no storefront, only pay for labor and supplies; the recommended approach is buying a certified loose stone online, verifying its cert number matches, then having a local custom jeweler set it.

Buyers say a lab diamond is chemically identical to a natural one but costs less and avoids the ethical concerns of mined stones, though one buyer pointed out lab prices have dropped so fast that resale or long-term value is essentially nonexistent.

The bride explained that tiny melee stones cost about the same to cut whether they are lab-grown or mined, since cutting small diamonds is labor-intensive either way, so her ring paired a lab center stone with mined side stones.

Buyers said it seemed expensive for only 3-4 grams of gold and recommended getting multiple quotes with the exact gold weight stated for a fair comparison.

The discussion says the amount of gold used drives most of the price difference between quotes, so a thinner claw setting costs less than a thick bezel even with the same stones.

Ask each vendor for the exact estimated gold weight and karat so the quotes can be compared like-for-like instead of by price alone.

One buyer found a second vendor quoting about $113 less for the same DEF/VVS moissanite quality, using a mix of 10k and 14k gold instead of solid 18k.

Buyers disagreed: some said large clear lab-grown diamonds did not exist in that size range decades ago and anything that big from that era is more likely sapphire or cubic zirconia, while others said mined colorless stones of 3 carats and up did exist in the 1990s, just at very high cost.

Buyers said real value comes from the cost of an equivalent loose stone plus the setting and labor to make it, not a store appraisal, and pointed to sites like StoneAlgo to check a stone's market price.

Several buyers, including trade insiders, blame an oversupply of cheap lab-grown diamonds crashing prices, noting half-carat stones that sold for $1,200 in 2002 now go for only $500-600.

Yes, buyers said lab-grown diamonds have almost no resale value to dealers since they're mass produced and constantly dropping in price, unlike natural stones which hold value slightly better.

Buyers said natural diamonds also resell poorly unless exceptional or historically significant; several reported resale offers far below purchase price on natural stones too, including a $1,000 offer on a $10,000 three-stone natural ring.

Buyers pointed to lab diamond buy-sell-trade communities online, where listings for similar rings showed sellers pricing around half of retail; one advised pricing at roughly half a reasonable retail price to actually sell, meaning a 2.5 carat lab ring would likely go for well under $1,000.

Buyers cited $250-$300 per carat from sites like Loose Grown Diamond and Ritani, well below the roughly $800 per carat once considered a great deal on DeBeers's Lightbox lab diamonds.

Yes, several owners said CZ tends to cloud and scratch within a few years unlike moissanite or diamond, but since it is so inexpensive it is easy to just replace periodically.

Several owners said the visual difference is barely noticeable at small round sizes even up close, so the main reason some still choose tiny diamonds is that jewelers can more easily source a replacement for a lost diamond than a lost tiny moissanite.

Guesses here ranged widely from about $400 to $3,200 with no real sale behind most of them, while people with actual builds paid roughly $1,090 to just under $3,000 depending on the setting and service level.

One buyer paid $1,090 total for a 2ct H VS1 round lab ring ($800 stone, $290 setting) in 2023, and another paid just under $3,000 for a similar design built through WhiteFlash with white-glove service.

One buyer says a Tiffany ring bought for over $90,000 in 2015 resold for about $60,000 around 2016-2017, a loss over $30,000, and Tiffany's own upgrade program would have required paying the full original price again, nearly $200,000, instead of a normal trade-in.

One custom order came in at 7.26 carats, E color, VS2 clarity, ideal cut, chosen deliberately over the up-to-5-carat stones the couple had already seen in stores.

Yes in dollar terms, buyers argue, because the starting price is so much lower: losing all the value on a $2,000 lab stone still costs less than the typical loss on a $15,000-20,000 natural stone of similar look.

One buyer says natural diamond studs with good color and clarity run into the thousands, so lab-grown is the realistic way to hit a $300-500 budget.

The buyer explained that heating a sapphire can brighten or enhance its color, while an unheated stone comes straight from the earth and is cut with its natural color unchanged.

Estimates ranged from about $870-$3,000 for the loose stone up to $4,500-$9,000 for a finished roughly 2ctw ring, well under what a natural stone of the same color and size would cost.

A natural 2ct vivid blue diamond would run into the millions, while a comparable lab-grown stone can be found for well under $3,000.

Buyers called it far too high. Lab diamonds were said to run under $500 a carat, and several people reported buying comparable or larger lab stones with settings for $600-$2,000 total, roughly half the asker's quote or less.

Readers pointed to lab diamond makers Provence and StarsGem, the retailer Brilliance for solitaire settings, and the sites loosegrowndiamond.com and Adiamor for cheaper finished rings.

One buyer paid $1,600 total for a 1.44 carat lab stone plus a local jeweler's fee to set it, well under the asker's quote for a smaller stone.

INSIGHT: a buyer noted a big budget like $10k on a lab-grown stone could buy something so large the wearer could barely lift her hand, using it to argue for lab-grown when upgrading.

Nearly every buyer said yes, pointing out that similarly specced lab stones plus a custom platinum setting typically ran $2,000-4,000 elsewhere, a fraction of the local jeweler's price.

Buyers recommended sourcing the stone directly from an online vendor and paying a jeweler separately to build the custom setting, saying it comes out far cheaper than a single full-service custom quote.

Buyers overwhelmingly said yes, estimating the same specs could be bought online for roughly $2,000 to $3,500, versus the far higher custom/local-jeweler price the person asking was quoted.

An independent jeweler in the answers explained that small stores pay higher per-stone markups than volume online sellers and sometimes have access to only one overpriced vendor for certain stones, costs that get passed on to the customer.

One buyer paid around $3,200 for a 4.66-carat GIA-certified lab diamond from an online vendor and had it set separately in solid platinum, landing the whole ring at just over $3,900.

Yes, nearly every buyer who priced a similar stone paid between about $1,100 and $6,000 for lab diamonds in the 3 to 7 carat range with comparable clarity and color, so $10k for roughly 3.25ct looks like double to triple the going rate.

One buyer warns IGI-certified stones are usually cheaper but their grading and reporting can be inconsistent, while GIA grading is viewed as more reliable.

Several buyers report online sellers such as WithClarity, Adiamor, RockHer, StoneAglo and Mureta & Co cost much less than local or franchise jewelers for similar size and quality, though buying in person lets you check sparkle and cut before committing.

Buyers pointed to Kuololit, a marketplace seller offering a three-link moissanite band ring similar to the Spinelli Kilcollin look, sold in 10k, 14k or 18k gold as well as silver.

Several buyers said it runs small because the connected-rings design leaves no slack, roughly half a size or more tighter than expected, and recommended ordering at least one size up from a normal ring size.

The person asking says she doesn't buy jewelry to impress others and just wanted to celebrate her wedding, while several buyers defended her choice, saying labs make big stones affordable and personal taste shouldn't be judged.

Buyers disagree on a fixed ratio; one says lab tends to run closer to a tenth of natural price rather than half, while a jeweler buyer argues the two markets aren't really comparable since lab is a manufacturing product getting cheaper over time and natural is priced on rarity and mining cost.

Buyers and sellers here put a ceiling of roughly $1,200 to $2,800 for a 3 to 3.6 carat, F-G color, VS1 lab stone, and most agree that spending anywhere near $20,000 on a lab stone means something has gone wrong, whether an inflated ratio expectation or an unnecessarily large stone.

Buyers recommend entering the stone's certificate number into StoneAlgo to see the same exact stone's listed price at other sellers, then asking your own jeweler to price-match; one buyer said this saved him $1,200, though another warned StoneAlgo's own valuations and recommended alternatives aren't always reliable.

One jeweler-affiliated buyer describes lab diamonds as a technology product trending toward bigger, better and cheaper, unlike natural diamonds which hold value through rarity, implying lab stones will likely keep losing resale value going forward.

Buyers said growth method alone shouldn't set price, but retailers can market one type as superior to justify charging more, even though a comparable 1ct D VVS2 stone can be produced equally cheaply either way.

One buyer explained only HPHT stones with metallic inclusions from their growth catalysts will read as moissanite on an electrical-conductivity tester, an issue CVD stones don't have.

Buyers disagreed: some said untreated CVD costs more for higher quality while post-growth treated CVD is cheaper, and that individual stone quality matters more than growth method.

One dealer recalled buying a 10-carat H VVS2 HPHT-related diamond in Antwerp for $108,000 and selling it for $120,000 back in 2006, noting how different the market looks now.

Buyers said this was overpriced, since comparable IGI stones were going for roughly $600 to $800, and one buyer found a nearly identical IGI stone through StoneAlgo at Rockher for over $5,000 less than a similar listing.

Buyers recommended cross-checking a stone's IGI certificate on StoneAlgo to find it listed cheaper elsewhere, and named Rockher, Rare Carat and Brilliance.com as options; one buyer said Rockher's service was good but stones ship from overseas and take a couple weeks.

Buyers said the price gap mostly reflects brand overhead, marketing spend, and brick-and-mortar stores (Blue Nile, James Allen) versus an online-only seller (Brilliance), not stone quality; buyers were advised to check the exact certificate number to confirm it's the same stone.

Several buyers reported good experiences and a 30-day return policy at Brilliance for a large stone at a rock-bottom price, suggesting very low prices reflect industry oversupply of lab diamonds rather than being fake.

A self-described lab diamond dealer explained that, unlike tightly-supplied natural stones, lab diamonds are produced by many independent companies without coordination, so oversupply drives some sellers to unload inventory far below what others charge for the same quality.

Buyers said the price was inflated: a similar oval lab diamond plus setting could be assembled online for around $1,600 to $1,845, since Jared and other mall chains mark up heavily versus specialist vendors sourcing the same overseas-cut stones.

One buyer explained that most vendors, big and small, buy from the same overseas lab-diamond cutters; big-box stores charge more for brand marketing and mall locations, not better stones.

One buyer paid $2,600 for a natural 1.25ct pave ring and $1,700 for a 1ct solitaire, both bought on behalf of relatives from Brilliance.com.

Numerous buyers reported paying $350-$2,500 total for custom lab diamond or moissanite rings from overseas or custom makers (GoldenBird, Diamondrensu, Ouros, Scott Bonomo) versus a $4,200 quote from Jared for comparable specs, though several noted overseas vendors typically don't offer a warranty.

Many buyers who chose moissanite paid $350-$1,000 total for rings with close to 2 carats of stone, saying the rainbow sparkle and lower cost made it worth it, though a few noted not every local jeweler will work on moissanite.

Buyers most often named Brilliance.com, Blue Nile, James Allen, Ritani, Loose Grown Diamonds, StoneAlgo and Grown Brilliance as cheaper sources for loose lab stones than mall chains like Jared.

A buyer explained lab diamonds from reputable vendors usually come with an IGI rather than a GIA certificate, while big-box stores' 'certificates' can be just paper stamped with the store's own logo.

Most buyers say no, calling it roughly double a fair price and estimating the stone is worth about $1,000-3,500 retail for those specs.

One buyer recommends D-H color if the budget allows, or switching to a lab diamond otherwise, and specifically warns against K color with faint fluorescence, though others here say lower grades like J or K can still look gorgeous.

One buyer got a GIA-certified 3.5-carat D/VVS2 lab diamond from the online seller Adiamour for $2,100 by price-matching a listing found at Rockher through Stonealgo, less than half what the natural stone here was quoted at.

One buyer argues yes for ovals specifically, saying lab and natural ovals look about the same, so choosing lab would save a lot of money for a similar look.

Based on similar sales described here, expect roughly 10-25% of the purchase price; a $4,700 ring sold quickly for $4,500, while a $9,000 ring only fetched $700 after extensive shopping around for buyers.

Buyers pointed to the an online group group as an active peer marketplace where lab diamond rings sell close to their original price, plus resale sites like Everything But The House.

One buyer said lab and natural diamond prices overall had dropped about 30% in the two years before the post, which pushes resale offers down too.

Yes, one buyer said they paid under $600 for a 1.77 ct ideal-cut lab-grown stone, far less than a comparable natural stone would cost, though some partners insist on natural only.

Top-quality untreated natural alexandrite can reach about $15,000 per carat under 1 carat, and $50,000-70,000 per carat above 1 carat, with per-carat prices approaching $100,000 around 10 carats.

Wholesale lab diamond costs are now just $50-200 per carat while retailers still charge over $1,000 per carat, and one jeweler noted current retail inventory was bought months or years ago at higher prices, so retail price cuts lag behind wholesale drops.

A wholesale jeweler said rough natural diamond prices dropped 30-35% year over year, though it takes time to show up in retail jewelry since existing inventory was bought earlier at higher prices.

Most buyers said it is tight but doable: a nice 1ct lab diamond alone runs about $500, and full quotes for melting the gold, making the setting and adding a decent lab diamond came in around $800-1,000 to $2,000.

Buyers warned these stones scratch and chip easily and would eventually need replacing, recommending sapphire, diamond, moissanite or alexandrite instead for daily-wear durability.

Opinions split widely: several buyers say 3 to 4 carats is a sweet spot that still looks elegant, while others feel anything past 3 carats starts to look costume-y and some love anything over 4 carats; the person asking ended up around 3.7 carats.

Buyers warn that fashion could snap back to smaller, daintier stones once big lab-growns become common, leaving buyers with an oversized ring that is hard to resell, though a lost or damaged lab stone is now cheap to replace.

Some say a big stone will still read as real and no one will assume otherwise, while others note people already assume any large stone is lab-grown or cubic zirconia regardless of price, which some buyers say no longer bothers them.

One buyer says these tiny lab stones are cheap, running around $10 each at the smaller sizes and about $30 at medium sizes, with cubic zirconia substitutes costing even less.

Some vendors use their own naming, calling stones grown by the pulled Czochralski method 'sapphire' and stones made by flame fusion 'corundum,' even though both fall under the same lab-corundum family in standard gemology, which is why reps sometimes misname what they're selling.

A basic thermal tester should not react to cubic zirconia or true sapphire, since both conduct heat far less than diamond or moissanite, so a positive reading on a stone sold as sapphire is a red flag worth confirming with a jeweler.

Many buyers said yes, big lab stones on someone without an obviously wealthy job or partner draw suspicion or comments, but most argued this stigma is outdated now that lab diamonds no longer require a matching income to afford.

The buyers's fiance bought their 2 carat lab-grown alexandrite ring at a jeweler called Willworks, which offers the same setting with different band metals and center stone sizes.

The buyers chose alexandrite as her birthstone and because it visibly shifts color across different lighting, from teal and green to blue and purple, unlike a diamond's fixed color.

The buyers's ring is set in 18k rose gold with lab-grown alexandrite as the center stone and small diamonds and alexandrites as side stones.

One buyer got a 2.2ct D VVS1 pear lab diamond for $758 when Rare Carat listed the same spec over $4,000, and another got a 2.5ct lab stone for a little over $1,000 versus a Rare Carat listing over $6,000.

One buyer used Loose Grown Diamonds for a steep discount on a pear-cut stone, but warned the customer service was poor, calling it the tradeoff for the low pricing.

Buyers said their moissanite stones developed a permanent cloudy 'oil slick' film after anywhere from about 18 months to 8 years of wear that no cleaning could remove, and noted moissanite sits at 9.25 on the Mohs hardness scale versus diamond's 10.

Yes, one buyer's original jeweler gave her a $450 credit for the old moissanite center stone, applied toward remaking the ring's setting for the new lab diamond.

One buyer noted that Charles & Colvard would replace a cloudy, oil-slicked moissanite stone under warranty.

Buyers most often name rose cuts and other antique-style cuts like jubilee, old mine and old European as clearly better in moissanite, since the stone's stronger double refraction adds sparkle that flatter, more subdued cuts often lack in diamond.

Several buyers say emerald and asscher cuts look nearly identical between the two stones in most lighting, with moissanite only flashing occasional rainbows in direct sun.

One buyer says lab diamonds actually show more bowtie in these elongated shapes than moissanite, though moissanite's slight cloudiness can be more noticeable there too, so it's worth seeing a larger stone in person before choosing.

Opinions split: some say a well-cut round moissanite is nearly indistinguishable from diamond aside from an occasional disco-ball sparkle, while others feel diamond keeps noticeably more depth at larger sizes.

Buyers say yes, a budget in that range easily covers a lab-grown diamond if bought online rather than from a physical retail store, which tends to carry a heavy markup.

Buyers spent well under $2,000 on moissanite rings and were happy with the brilliance, while a couple of buyers warned it can throw rainbow flashes that read as less diamond-like in some light.

A handful of buyers expressed mixed feelings, wishing in hindsight they had chosen a cheaper ring, a different stone, or gone lab-grown instead of natural, though most said the amount spent made no difference to their happiness.

No, the sub's consensus is that this is a severe overcharge: a 2.5-3ct moissanite ring should run from under a hundred dollars to about $2,000, and the same money could buy a multi-carat lab diamond instead.

Several buyers note lab diamonds have gotten so cheap that a 4-9 carat lab diamond can now cost about the same as, or less than, a comparably priced moissanite from a retail store.

Frequently named sellers include Etsy or overseas shops such as Shy Jewelry, Provence Jewelry, Ring Come True, Kuololit, MoissaniteCo and Charles & Colvard, where full rings ran roughly $50 to $3,000.

Buyers are told to ask about metal type, warranty, design turnaround and whether the setting is cast or hand-smithed, since these factors shape a custom quote as much as the center stone.

No - multiple buyers say GIA is already the most reputable lab and a second report on the same stone adds no useful information, just extra cost.

One buyer asks this, but confirms after re-reading that the figure is a per-carat price rather than the total, which resolves the concern about it being suspiciously cheap.

Buyers called $5200 way overpriced for the specs, but said $2800 was much more reasonable; one put the general lab diamond market rate at around $400 per carat.

Buyers recommended asking the seller for a real, non-360-render video, since stock 360 spins can look fuzzy and misrepresent the stone's actual clarity.

The buyer wanted a custom natural-stone tennis bracelet for well under $2,000, and buyers suggested shopping vintage pieces, Etsy, or a local gem and jewelry show instead of commissioning something new.

Opinions were mixed: several buyers said it looked inflated next to similar-sized stones listed for $13,500-$21,000 at reputable dealers, while others said an untreated, well-saturated, certified sapphire this size can legitimately be worth that much.

One buyer said lab sapphires currently come in only a few shades per color, so buyers wanting an unusual blue-purple hue may need to look at natural stones or tanzanite instead.

One gemologist cites unheated pink sapphires reaching around $7,500 per carat at cost, not retail, in some sizes, so a large fine unheated blue sapphire in the $20K+ range isn't out of the question.

One buyer paid $6,200 for a 2.5-carat natural M color VS2 diamond with excellent polish and symmetry from Brilliance, and had it appraised at nearly four times that price.

Buyers said a 3 carat round stone should measure about 9mm across, and several thought the pictured ring looked closer to 1.5-2 carats by that standard.

A thicker band with side stones (pave) can make the center stone look smaller by contrast, while an ultra-thin plain band makes the same stone look larger.

Buyers suggested holding a mm/cm tape measure across the stone or buying a cheap digital caliper (around $7 on Amazon), since moissanite is usually described in millimeters rather than carats.

Not necessarily: one writer's husband first ordered a mined stone assuming lab would be a downgrade from her original mined set, but switched the order to lab once he learned there's no visible difference, freeing up the saved money for other things.

One writer said she couldn't point to a noticeable visual difference between her original mined stone and her new lab-grown one, which was the main hesitation before her husband agreed to switch.

Most buyers say it's largely personal preference for a warmer-looking stone, plus the price gap (roughly $1200 versus $2800 here's example) is a lot of money for many buyers when there's no visible difference to someone glancing at the ring.

The person asking argued IGI-graded stones often come in about one color and one clarity grade more generous than GIA would give, but other buyers pushed back, saying that framing presumes all IGI stones are automatically lower quality.

Several owners who have both grades said nobody around them can tell the difference once set, especially in yellow or rose gold, so many choose G-H deliberately for the look or the savings rather than settling for it.

Buyers overwhelmingly called it a rip-off, estimating the loose stone alone should run $1,000-$1,500, with several buyers reporting $1,600-$2,050 for comparable or better lab diamond rings bought elsewhere.

Yes, buyers described paying under $2,000 total by sourcing the stone from one online vendor and the setting from another, then having a local jeweler assemble it, versus $10k quoted for a comparable finished ring.

One buyer said $10k is closer to what a mid-range natural emerald cut diamond costs, implying a lab stone with similar specs should cost far less.

A lab diamond manufacturer and several buyers say StoneAlgo only pulls prices from a handful of partnered retailers with high margins, so its suggested prices often run around 40 percent, sometimes double, what you can find by shopping directly or asking in diamond groups.

Buyers recommend browsing diamond-focused groups directly for many personalized options, or buying straight from manufacturers and sellers like Loose Grown Diamond or Sagems.co rather than the retailers StoneAlgo surfaces.

A jewelry-trade wholesaler here says lab-grown diamonds sell back to the trade for at most about $100 per carat no matter what was originally paid, while natural diamonds typically fetch no more than half their original price on resale.

A jeweler traces a wholesale 2-carat lab stone from about $6,000 in 2019 down to roughly $4,500 in 2020, $3,000 in 2021 and around $300 by 2024 as production capacity scaled up.

A trade wholesaler says lab stones bought at retail for $4,000, $10,000 and $32,000 were each only worth $75 to $475 to a jewelry buyer, and dealers can source new lab goods at about 99% off list price.

Buyers point to overseas wholesale markets — a trade show in Hong Kong and dealers in Thailand — where lab stones were selling near $100 per carat wholesale as of the 2024 post.

Reviews were mixed: many owners reported their DiamondRensu rings holding up for 1 to 3+ years with no issues, but a few said a stone arrived rattling loose or the piece looked cheap in person, with the worst reports dating from a couple of years earlier when the shop had acknowledged quality problems.

Jewelers here said $2,500 was reasonable to good for an all-lab-stone custom design, since base CAD, design and labor alone typically starts around $2,400 before stone cost, though the person asking could still ask the jeweler to work toward $2,000.

Several buyers advised against it, since emeralds are fragile and hard to judge for quality from photos or video; an in-person inspection with a loupe was recommended.

Buyers pointed to the group's vendor list, Etsy sellers like Scott Bonomo and Kuololit, and Charles & Colvard, saying most buyers here order online or go custom rather than through brick-and-mortar stores.

One buyer ordered a custom 6-prong ring from Kuololit on July 25 and received it August 12, paying $360 total.

Several buyers grabbed a 50%-plus-8%-off deal on 6ct round moissanite for about $31-32 each, reasoning Amazon's easy return policy made it low-risk; the stones arrived with GRA certificates and looked sparkly in person.

One buyer said her engagement ring's Charles & Colvard Forever One moissanite is clearly marked on the girdle, but wasn't sure whether cheaper stones from overseas Amazon/Alibaba/AliExpress sellers carry the same marking.

A buyer noted a moissanite tester can confirm authenticity in about five seconds, and since the stone shipped through Amazon, anything that failed the test could simply be returned.

One skeptical buyer argued moissanite that small shouldn't be priced that low and said she only buys it from Charles & Colvard through JTV.com, while other buyers here felt Amazon's return policy made the cheap deal low-risk either way.

Buyers explained that retail jewelers price in a large markup, and a jeweler buying back a stone has to buy low since they aren't guaranteed a buyer for that exact stone right away; typical resale offers run about 20-50% of what was originally paid, with lab diamonds usually landing at the lower end since new lab stone prices keep falling.

One buyer estimated roughly $300-400 per carat for secondhand lab stones, though this varies a lot by carat size and was said to be changing quickly as new lab diamond prices keep falling.

One buyer said crushed ice faceting is used to intensify the perceived color of pale fancy-colored rough stones, at the cost of some brilliance.

One buyer with prior Ritani purchases said going through a jeweler who sources from the same vendors just adds markup, though another shopper found Ritani's stones inconsistently graded and skipped it for that reason.

One shopper asked whether just over $1,000 for a 0.38 carat natural Fancy Light Brownish Pink diamond (VS2 clarity) was overpriced, without a clear consensus given here.

One buyer got a 1.77ct D color VVS2 ideal-cut lab diamond in a fully customized petal-style setting, with unlimited CAD revisions, for under $2,000 total.

One buyer bought a 6-carat pear lab diamond as a separate statement piece while keeping her actual 3-stone emerald-cut engagement ring for everyday wear, saying she wasn't sure the bigger stone was practical daily.

A buyer paid $372 for a custom 10k yellow gold, 3-stone high-dome rose cut moissanite ring from Provence maker Jasmine, plus $30 FedEx shipping and a $12 AliExpress processing fee, about $414 total.

One buyer said she had read a wave of bad reviews about the shop while her order was in progress, but her own experience with maker Jasmine was smooth and responsive, including a CAD change, a side-stone recut, and prong adjustments handled without pushback.

One buyer believed most of Costco's stones are natural, while the broader discussion noted lab-grown diamonds are increasingly common and cheaper across the industry.

One buyer had hers custom made by a maker named Sam at Kuololit in 10k yellow gold with VS1, GH-color lab diamonds, and said the price was reasonable, though she only shared the exact figure by DM.

Around $7,175 for a G/VS1 and $9,950 for a D/VS1 ideal-cut round, based on Whiteflash listings cited here.

Buyers said no, calling it a poor value for the specs and urging the buyer toward a colorless, eye-clean stone with a real certificate for similar or less money.

Buyers disagreed sharply: some said natural stones appreciate over decades while lab diamonds don't hold value at all, but others argued natural diamonds aren't real investments either since resale prices usually fall far below the appraisal, which exists for insurance purposes rather than resale.

One buyer said a lab-grown stone of similar look costs considerably less than a natural of the same size, which eases worry about theft or loss, and noted insurance also covers the risk either way.

Yes, buyers reported moissanite and lab diamond rings ranging from about €300 to €1,000 including setting, and several specific moissanite solitaire listings priced at €545-800.

No, buyers say: loose moissanite typically runs about $10-25 a carat, far below lab diamond prices, so a jeweler charging the same amount either way is likely pricing the moissanite at diamond-level markup.

Experienced buyers suggested a minimum band thickness of 1.8mm and width of 2mm for a stone that size, going wider still for a peg-head setting.

Lab-grown diamonds let buyers get a bigger stone for less money, which is shifting demand, especially among younger buyers, away from natural stones.

Buyers showed off sapphires (blue, cornflower-lavender, Padparadscha, Montana), morganite, lab-grown alexandrite, salt-and-pepper diamonds, and moss agate as popular non-traditional center stones.

Buyers blame online feeds and cheap lab-grown and moissanite stones that make big sizes affordable; one in an average cost-of-living area says most people around her wear under a carat.

Results are mixed: an heirloom's thin band broke twice, another warped over generations, a tension setting kept loosening, and one owner who cracked her 0.81 ct diamond in a drop swapped in a moissanite; a dainty Etsy-made ring held up well over 5+ years.

A buyer argues the shift is mainly because lab-grown diamonds made large stones far more affordable, so more buyers now choose bigger stones simply because their budget allows it, not because tastes changed.

Most buyers said no: natural emerald inclusions, called 'jardin', are expected and often preferred, seen as proof the stone is genuinely natural, with color treated as far more important than clarity when judging an emerald.

Several buyers said a totally inclusion-free emerald in an affordable price range is likely lab-created, since natural emeralds almost always carry some visible inclusions unless the buyer is paying a very steep premium.

One buyer said Tianyu Gems does completely custom jewelry work at incredible prices and had a good overall experience, though he didn't share the final cost and needed several design iterations before landing on the finished piece.

Most reviewers who bought loose diamonds said Luvansh shipped fast (2-6 days via FedEx), the stones matched their laser-inscribed certificate numbers, and prices ran hundreds of dollars below other online sellers for the same specs, though a couple of buyers described serious trouble getting a jewelry order shipped or receiving the wrong item entirely.

Prices varied widely: about $219-$350 for roughly 1.2-1.6 carat colorless stones from Luvansh or Ritani, versus $487-$534 for similar sizes with comparable color and clarity from Brilliance, showing how much cheaper some newer online sellers had become than established ones.

A frequent buyer who custom-makes rings said retailers can mark up a diamond that costs them $600 wholesale to about $5,000, and a setting that costs $800 wholesale can become an $8,000 branded ring, so looking up a stone's certificate number often turns up the identical diamond listed for thousands less elsewhere.

Buyers said that once lab diamond prices fell as low as some discount sellers now offer, moissanite stopped being the better deal unless it cost well under $100 a stone; one buyer's quote of $760 for a 3-carat moissanite ring with setting overseas lost out to the idea of a diamond for under $2,000.

Buyers said sellers, especially on Etsy, sometimes label cubic zirconia as "lab diamond" because that term predates today's lab-grown diamonds, so an unusually cheap "lab diamond" listing is almost always CZ, not a real lab-grown stone.

No, buyers clarified that cubic zirconia and zircon are both simulants, distinct from each other and from actual lab-created or lab-grown diamonds, and a seller calling CZ a "lab diamond" is misleading buyers.

Several buyers warned that some Etsy sellers, especially certain overseas shops, misrepresent CZ as lab diamond, and one buyer said their ring failed a diamond tester and the shop disappeared before they could get a refund.

Recommended sources include Etsy and vetted AliExpress/Alibaba sellers such as Kuololit, Starsgem, Tianyu Gems, Mona and Fiorese, plus US sellers Scott Bonono and Debebians (Kori Moissanite line); the group keeps a vendor list.

Yes — buyers point to several vendors (Kuololit, Causyou, DiamondRensu, Scott Bonomo) where similar rings run from $291 to around $800, well under the asker's budget.

Kuololit (contact Sam), Tianyu, Starsgem, Causyou and DiamondRensu come up repeatedly, with buyers reporting finished rings from $291 to about $770.

No — a buyer explains moissanite has no official industry grading standard like GIA's diamond scale, so any vendor-listed color or clarity is only an approximation.

Several buyers note lab-grown diamonds are now price-competitive with moissanite at that budget, so the choice comes down to taste — moissanite's rainbow flash versus a diamond's crisper white sparkle.

One buyer paid about 2,570 euros all-in, including import duties, for a 1.35-carat F VVS1 hearts-and-arrows oval lab diamond from JannPaul, plus roughly 810 euros for a custom 18k gold and platinum setting.

The buyer estimated a natural diamond of similar 1.35ct F VVS1 quality would start around $10,000-14,000 including tax, with a precision hearts-and-arrows cut pushing that to about $14,000-18,000.

Buyers named JannPaul in Singapore and Brian Gavin as the two known specialists who cut true hearts-and-arrows ovals to order.

The buyer paid $291 for a 5 ct (9x11mm) emerald-cut moissanite in a 10k yellow gold cathedral setting from Kuololit, noting the 5-carat size cost only a few dollars more than the store's 4-carat (8x10mm) version.

A buyer suggested two thin 2mm moissanite stacking bands to balance a large stone, and the buyer planned to buy a pair during a November sale.

LGD is a website that sells lab-grown diamonds, often listing the same stones found elsewhere for nearly half the price, though buyers advised researching the seller first.

The owner of a 4+ carat lab solitaire reset into a 3-stone ring said the finished piece would run into six figures if it were built from mined diamonds instead of lab-grown ones.

Yes, one owner kept their original lab solitaire, bought two extra 1 ct lab side stones separately, and had a local jeweler combine them into a 3-stone setting with a matching band.
