Sell Your Platinum Jewellery
We are specialist buyers of platinum jewellery — engagement and wedding rings, diamond pieces, earrings and chains. Platinum is rarer and more valuable than most people realise, and our valuations reflect both the metal and the piece.
What Is Your Platinum Worth?
Send us a photo of your platinum jewellery and its hallmark for a free, no-obligation valuation — or simply ask for honest advice. Our specialists reply within one working day.
Platinum is the most precious of the everyday jewellery metals — rarer than gold, denser, and hallmarked at 95% purity. Yet because it looks so similar to white gold, platinum is one of the most commonly under-valued things people sell. We make sure that doesn't happen: we identify your metal correctly, weigh it precisely, and pay for what it really is.
At Mozeris Fine Antiques we buy platinum jewellery of every kind, from showrooms in Mayfair and Essex. If you're not certain your piece is platinum at all, start with our guide to whether your ring is platinum or white gold — then come back here to sell.
Platinum jewellery we buy
Engagement & Wedding Rings
Platinum is the classic choice for fine engagement and wedding rings, especially diamond solitaires and eternity bands. We buy single rings and full sets, and value the diamonds as well as the metal.
Diamond Jewellery
Platinum-set diamond earrings, pendants, bracelets and brooches. The platinum and the stones are each valued on their merits.
Plain Bands & Chains
Plain platinum wedding bands, neck chains and bracelets carry strong intrinsic value by weight at 95% purity.
Broken & Scrap Platinum
Damaged, single or odd pieces still hold real value — platinum is valuable as metal regardless of condition. Never assume a broken piece is worthless.
What Determines Your Platinum's Value
Every offer we make is built on a clear, explained assessment:
- Purity — 950 (95%), 900 or 850 platinum, confirmed by the hallmark.
- Weight — Precisely weighed on calibrated scales; platinum is dense, so weight matters.
- The live platinum price — We value against the current market on the day.
- Diamonds & gemstones — Set stones are assessed and valued separately.
- Maker & design — A signed or finely made piece can carry a premium above metal value.
- Condition — Even damaged platinum holds strong metal value.
We always confirm the metal first — many "white gold" pieces turn out to be platinum, and vice versa.
How to Sell Your Platinum
A straightforward, no-obligation process from first photo to payment.
Photograph It
Take clear photos of the piece and, importantly, the hallmark inside the band or on the clasp. Raking light from a torch makes small marks easier to read.
Send It Over
Use our quote form or email info@mozerisfineantiques.com. Tell us anything you know about the piece. There's no charge and no obligation.
Receive Our Valuation
We confirm the metal, weigh and research the current platinum market, then come back to you — usually within one working day — with an honest assessment.
Agree & Get Paid
Happy with the offer? Visit us by appointment in Mayfair or Braintree. Payment is made immediately on agreement.

Frequently Asked Questions
Selling platinum jewellery — your questions answered.
How much is platinum worth per gram?
Platinum trades on a live market that moves daily, and dealers pay a rate below the spot price that reflects purity (950, 900 or 850) and refining. We value your piece against the current market on the day and explain exactly how we reach the figure — request a free valuation for today's number.
Is my platinum ring worth more than white gold?
Usually, yes. Platinum is rarer, denser and hallmarked at 95% purity, so it generally carries more intrinsic value than white gold of similar size. If you're not sure which you have, see our platinum-or-white-gold guide first.
Will you buy a platinum ring with diamonds?
Yes. We value the platinum and the diamonds separately, so you're paid for both. Engagement and eternity rings are among the pieces we buy most often.
Can I sell broken or single platinum pieces?
Absolutely. Platinum holds strong value as metal regardless of condition, so a broken ring, a single earring or a damaged chain is still well worth selling. Don't assume it's worthless.
Do you buy platinum in person or by post?
We ask for photographs first, then arrange a visit by appointment at our Mayfair or Braintree showrooms. Call 01376 334 482 to discuss the best option for your piece.
