Sell Platinum Jewelry for the Highest Price in Los Angeles
South Bay Coin is a licensed refinery and the platinum jewelry buyer in Los Angeles that pays more. Walk in for a free, no-obligation appraisal and leave with same-day cash.
The Best Place to Sell Platinum Jewelry in Los Angeles
South Bay Coin is the most trusted place to sell platinum jewelry in Los Angeles, a licensed, bonded, and insured precious metals dealer that has served the South Bay since 1980. For more than 45 years, families across Los Angeles County have brought us their platinum rings, wedding bands, and estate pieces and walked out with the highest cash offer in the area.
Most platinum buyers in Los Angeles are not equipped to test platinum correctly. Inexperienced shops routinely mistake platinum for white gold or palladium, an error that can cost a seller hundreds of dollars on a single ring. South Bay Coin is a working refinery, not a middleman, so we identify the exact metal and purity in front of you and pay based on real platinum content rather than a guess.
Because we process and refine platinum ourselves, we skip the markup that pawn shops and jewelry stores build in when they resell your piece to a third party. That difference goes straight into your payout. Whether you are parting with a ring from an old engagement, downsizing an inherited collection, or selling a designer piece, every appraisal is free and there is never any pressure to sell.
Our appraisers test, weigh, and explain every offer using the live platinum spot price, the same number you can verify for yourself. We also buy gold and silver and work with trusted luxury watch buyers, so you can bring everything in a single visit.

Live Precious Metal Spot Prices
Updated every 60 seconds during market hoursHow We Value Platinum Jewelry
Platinum jewelry has a measurable, predictable value built from three things: purity, weight, and the current platinum spot price. Platinum is far purer than gold jewelry. A typical platinum piece is stamped PT950, meaning 95% pure platinum, compared with 58.5% for 14K gold and 75% for 18K gold. Lower grades exist too, marked PT900 (90%) or PT850 (85%), and we read every hallmark before testing.
Weight matters because platinum is dense, noticeably heavier than gold or silver of the same size, so even a small band can hold real value. We weigh each piece on a state-certified scale in front of you, convert grams to troy ounces, and apply the purity factor to find the pure platinum content. Acid testing and electronic verification confirm the metal so there is no guesswork and no chance of platinum being undervalued as white gold.
Jewelry pays a little under bullion because it must be refined back to investment-grade purity, work that bullion has already had done. As an in-house refinery we keep that cost low and pass the savings to you. Designer and antique platinum from houses like Tiffany, Cartier, and Van Cleef & Arpels, along with Art Deco and Edwardian pieces, often carries collector value well above melt. See the designer jewelry we buy and we will appraise for both.

What Our Customers Say
Common Questions About Selling Platinum Jewelry
Your platinum jewelry's value comes from three things: its purity, its weight, and the live platinum spot price. A PT950 piece is 95% pure platinum, so we weigh it, confirm the purity, and pay based on the actual platinum content. Because South Bay Coin refines in-house, we pay a higher percentage of spot than most Los Angeles buyers.
Platinum and white gold look similar but behave differently. Platinum is denser, so it feels noticeably heavier, and it is usually stamped PT, PLAT, PT950, or PT900, while white gold is marked 14K or 18K. Acid and electronic testing confirm the metal. Many shops confuse the two, which is why accurate testing protects your payout.
Platinum purity is stamped as a three-digit number. PT950 means 95% pure platinum, the most common standard for fine jewelry, while PT900 is 90% and PT850 is 85%. In the United States, a piece marked only Platinum, PT, or PLAT must be at least 95% pure. We read every hallmark, then verify it by testing.
Platinum has traded near multi-year highs through 2026 after a strong run, so many sellers are seeing unusually favorable offers. Prices move daily, so the best approach is to check the current platinum spot price and get a free appraisal. We weigh and quote against the live market the moment you walk in.
Yes. We buy platinum engagement rings, wedding sets, and diamond mountings of every style. We value both the platinum and the diamonds, and we appraise designer pieces from Tiffany, Cartier, and Van Cleef & Arpels for their full worth. Bring the original box or paperwork if you have it, though neither is required.
South Bay Coin in Lawndale buys platinum jewelry for same-day cash and serves Torrance, Redondo Beach, Manhattan Beach, Hawthorne, and the wider South Bay. Walk in with no appointment, get a free appraisal, and leave paid the same day. We are a licensed, bonded California precious metals dealer trusted since 1980.
We start by reading the hallmark, then confirm the metal with acid testing and electronic verification so platinum is never mistaken for white gold or palladium. Next we weigh each piece on a certified scale in front of you and apply the purity factor and live spot price to calculate your offer.
Yes. Condition does not lower the value of the platinum inside a piece. We buy broken chains, bent bands, single earrings, and unmarked items, testing each one to confirm the metal and purity. Worn or damaged platinum is paid at the same rate as the pure content it contains.
Spot price reflects pure, investment-grade platinum, while jewelry must be refined back to that purity before it can be reused. That refining work is built into every buyer's offer. As an in-house refinery, South Bay Coin keeps those costs low and pays a higher share of spot than resellers who outsource the process.
A pawn shop resells your platinum to a refiner and keeps the markup, and many cannot test platinum accurately. South Bay Coin is the refinery, so we pay for true platinum content with no middleman. We test in front of you, explain the offer, and back it with a 45-year track record.
