Sales tax and tariffs: 33 Questions Buyers Asked

Buyers say yes - a 1.93ct GIA-origin unheated Ceylon sapphire landed in Australia for about $9,596 AUD including 10% GST, versus local Australian jewelers quoting around $12,000-14,000 USD for a similar-size stone or bespoke ring.

The buyer, based in California, was billed an extra 9.5% import/use tax on the ring's sale price by the California tax authority after the ring cleared US customs from Singapore.

The buyer's home country added a 25% VAT on top of the diamond's base price, turning a $2,837 pre-tax quote into $3,446 after tax, and he noted the tax applies to all goods sold there, not just diamonds.

One buyer said gold prices were already rising well before any tariff talk, driven by broader market factors rather than tariffs specifically.

A 10% US tariff on Indian natural-diamond imports (after a higher 27% rate was paused) plus tariffs on Chinese-made lab diamonds are raising costs and creating supply uncertainty for both categories.

Buyers note gold jumped from under $2,000 an ounce in 2020 to nearly $3,700 by early September 2025, including about a $200 rise in roughly a week, and several US jewelry brands warned they would raise gold jewelry prices on October 1 because of tariffs, so many buyers were rushing to buy before then.

One buyer of a $40 Etsy moissanite ring from India paid no shipping or tariff charges, with the ring taking about a month door to door.

One buyer reports Indian import tariffs on diamonds dropped from a January 2026 high of 50% down to 10%, which is starting to lower new inventory prices.

INSIGHT: buyers were especially impressed that this padparadscha was natural with no heat treatment, treating it as a major value driver alongside its rare color.

A jeweler here thinks it's a bit high, estimating the same stone is worth closer to $1,600-1,700 CAD including tax at current internet-retail prices, though the buyer says it was still the best of five quotes received.

One buyer reported paying about $40 CAD in duty on roughly a $1,000 USD parcel value for a diamond shipped into Canada.

One buyer said a friend got a 3-carat GIA-certified lab diamond from Alibaba for about $600 and had it mounted locally in Toronto for about $2,500, calling it a legitimate and much cheaper route than buying pre-set.

The jeweler said he ships pieces internationally insured as costume jewelry through a courier rather than declaring them as fine jewelry, which keeps the tariff rate low for buyers, though one buyer warned this practice could raise legal or customs concerns.

Buyers, including working jewelers, say the price mostly pays for brand marketing, overhead, and labor rather than material weight; one cites roughly £55 per gram for 9ct gold plus labor, tax and a standard 2x retail markup as a normal pricing model even for very light pieces.

The person asking says a private jeweler sourced stones with strong specs on paper, but none of them had the sparkle or wow factor the couple wanted until seen in person under different lighting.

One buyer who researched this said the main friction is slower back-and-forth from time zone differences rather than customs seizure, and reported normal delivery with no customs issues.

One Australian buyer had their parcel flagged as a biohazard by customs, causing a stressful delay, but the company still accepted a no-fault return afterward when the stone turned out too small and let them buy a replacement.

Buyers reported paying roughly 20 to 30 percent of the diamond's value in VAT and duty on top of the sticker price when shipping from outside the country.

Buyers cited roughly 22% VAT plus duty when importing a diamond into Italy, and advised European buyers to budget about 30% above a US site's listed price once VAT, duty and shipping are added.

Buyers warned that cruise-port jewelers can use high-pressure tactics and inflated tags, recalling a nearly $11,000 ask for a heavily included 1-carat diamond, and advised checking reviews and comparing prices before buying.

FedEx flagged the shipment and required extra paperwork, including a signed statement that the diamonds weren't from Russia and a power of attorney for customs clearance, causing multi-day delays each way.

One buyer calculated about $2,800 in VAT and customs on a $10,000 stone imported into Ireland — roughly 28% — enough that he considered flying to the US himself to collect a stone instead.

One buyer's experience was that there is no duty on natural diamonds or gemstones bought in the US, only GST and PST, though the buyers was not fully sure this covers lab diamonds too.

Buyers should budget for GST, duty, and shipping/handling fees on top of the purchase price and shipping cost, plus a worse credit-card exchange rate; one buyer's US$1,800 purchase ended up costing just under AUD$3,500 after conversion and fees.

A Canadian buyer noted she paid no duties or tariffs on her antique gold wedding band because it was already located in Canada when purchased, while wondering whether new US-vendor tariffs would eventually raise prices passed on to buyers.

Diamonds sourced from India were expected to rise about 27% under new tariffs, and some tracked online listings had already jumped $50-100 within weeks.

Industry members expected a roughly 10-25% (about 15%) jump on India-cut diamonds, including inventory already in the US but not yet invoiced, possibly hitting online listings almost overnight around August 1, 2025.

A buyer expected only the usual customs duties and taxes on a US-bought stone shipped abroad, and another buyer noted that current US tariffs are part of why an overseas source can look cheaper than buying directly from a US vendor.

The person asking said US tariffs pushed stones from Indian dealer safes into the US market and raised prices, but expects prices to fall again if tariffs return to zero, while many mines stay loss-making long term.

The Supreme Court ruled 6-3 that the administration had exceeded its constitutional authority by imposing emergency tariffs without Congress, putting roughly 200 billion dollars in collected tariffs in question, but the administration reportedly moved to reinstate a global tariff under a different legal authority within days.

Forum members noted the earlier US tariff exemption for natural-resource diamonds could still apply to Antwerp, while a new global tariff reportedly rose from about 10 to 15 percent, leaving unclear whether the roughly 40 percent tariff previously discussed for India would still apply.

The buyer estimated Singapore's tax at around 7% on top of the diamond price, though wasn't fully certain.

Buyers report a similarly specced stone costing noticeably more in the USA than in India or Australia, which a dealer attributes mostly to import duties and taxes rather than differences in supply.
