Questions about buying from Rare Carat

How much does a Rare Carat engagement ring cost?

Buyers paid a median $2,800 for rings from Rare Carat across 61 purchases, half between $1,768 and $3,800. Lab-grown diamond rings there came to a median $2,600 across 50.

Is Rare Carat good for engagement rings?

Of 45 buyers who described their own experience with Rare Carat, 42 recommend it, 3 are mixed and 0 warn against it.

Is Rare Carat cheaper than other online jewelers?

The $2,800 median at Rare Carat is above the $2,146 median at other online jewelers (439 rings). Lab-grown stones made up 94% of Rare Carat rings against 74% at the others, which accounts for part of any gap.

How does Rare Carat's price match work?

You have to find the exact lab-grown stone (by its LG number on the IGI or GIA certificate) at a competitor like Calavera and send Rare Carat that info through chat; they match the price but don't source a comparable stone for you. Buyers find the same diamond by its IGI certificate number listed cheaper on a site like Loose Grown Diamonds, then ask Rare Carat's customer service to match that price before it's turned into a ring; Rare Carat's own listed prices are normally well above other brokers.

How does price matching work for lab diamonds on Rare Carat?

Buyers find a stone they like on a site like Calavera or Loose Grown Diamonds using its IGI or GIA report number, then have Rare Carat match that lower price; one buyer saved almost $8,000 this way. Rare Carat matches the price of the exact same certified stone, verified by its certificate number, found cheaper elsewhere - not just a different stone with matching specs - and mostly applies to loose stones since matching gets trickier once a setting is added.

Are Rare Carat's lab diamond prices normal, or inflated compared to competitors?

Buyers found identical diamonds priced $600 to as much as $3,700 cheaper at competitors like Loose Grown Diamond and Luvansh, but said Rare Carat will price-match once you find the same stone by its IGI certificate number.

Are RareCarat, Adiamor, Blue Nile and Ritani listing the same diamonds?

One buyer pointed out that two listings from different resellers (Adiamor and RareCarat) were the exact same physical stone priced about $400 apart, because many online sellers pull from shared inventory feeds.

Can price-matching between online diamond retailers like RareCarat and Ritani actually save money?

Yes, one buyer said RareCarat price-matched a listing he found at Ritani for the same lab diamond, which cut $5,000 off what he would have paid.

Can you price-match lab diamond prices between online vendors like Rare Carat?

Yes, one buyer got Rare Carat to match a price found at Calavera, dropping the quote for an 8.53-carat stone from around $8,000-9,000 to about $2,200.

Do big retailers like James Allen, Blue Nile and Rare Carat all charge the same for the same diamond?

No, one buyer says the same wholesale stone can carry very different markups across resellers, sometimes 20 to 50 times, so it pays to compare the identical stone across multiple sites before buying.

Do cheaper lab diamond sites like Aurelinne and Calavera sell the same stones as Rare Carat?

The person asking said these sites largely drop-ship from the same third-party suppliers rather than holding their own inventory, which is why the same certificate number turns up across multiple sites.

Does Calavera or Loose Grown Diamonds give better prices for matching against Rare Carat?

Several buyers found Calavera generally has lower listed prices than Loose Grown Diamonds, so checking both before price-matching gets the better deal.

Does Rare Carat actually honor price matching?

Yes, several buyers got Rare Carat to match competitor listings, cutting listed prices by roughly 40% to nearly 75%, for example $18,000 down to $4,500 and $11,000 down to $5,000.

Does Rare Carat price-match other online vendors?

Buyers reported Rare Carat matching lower prices found on sites like Brilliance.com and Ritani, saving roughly $2,000 to $3,000 on a diamond.

Does Rare Carat raise a diamond's listed price the more times you view it?

Some buyers suspect Rare Carat or its wholesalers may raise a stone's price the more often the same listing gets viewed, similar to how flight-search prices seem to climb, though this was unconfirmed; one buyer saw a listed lab diamond jump by nearly $1,000 within the same day.
