Why Sell Your Platinum Ring at South Bay Coin
When you want to sell a platinum ring in Los Angeles, you want a buyer who truly understands the metal. South Bay Coin has appraised and purchased fine jewelry from our Lawndale showroom since 1980, and platinum is one of the rarest, densest, and most valuable metals we handle every week.
Our buyers are GIA-trained and test every piece on-site, so you can see exactly how your offer is built. You are never handed a flat, take-it-or-leave-it scrap price. If your ring holds diamonds, we also buy diamonds and diamond rings and value the stones separately from the platinum mounting.
There is no mailing, no waiting on a check, and no consignment period. Walk in from anywhere in the South Bay, get a clear and transparent number, and leave with cash the same day.

How We Value Your Platinum Ring
Platinum jewelry is usually stamped PLAT, PT950, PT900, or 950, meaning roughly 90 to 95 percent pure platinum. The value of your platinum ring starts with its weight in grams, then factors in that purity and the current platinum market. Because platinum is denser than gold, even a modest ring can carry real weight on the scale.
Heavier bands and higher-purity pieces bring stronger offers. We also buy gold and other precious metals across Los Angeles, so white-gold, mixed-metal, and matching sets are never a problem to evaluate in one visit.
Any diamonds or colored gemstones are graded and priced on top of the metal value, never quietly melted away. You see the full breakdown, metal plus stones, before you decide whether to sell.
Platinum Rings We Buy for Cash
From a single worn wedding band to a diamond engagement ring or an inherited estate piece, we evaluate and pay cash for platinum in every form.
Platinum Wedding Bands
Plain, milgrain, and comfort-fit platinum wedding bands and matching sets. Worn, scratched, or bent rings are welcome, since we pay for the platinum content, not the condition.
Platinum Engagement Rings
Solitaire, halo, and pave platinum engagement rings. We appraise the platinum mounting and grade center and accent diamonds separately for a higher combined offer.
Vintage & Estate Platinum
Art Deco, antique, filigree, and signed designer platinum rings. Hallmarks and provenance can lift your payout well above simple melt value.
Broken & Scrap Platinum
Cracked shanks, lone settings, single rings, and odd platinum scrap. Nothing is too small or too damaged to weigh, test, and turn into same-day cash.

South Bay Coin vs. Other Platinum Buyers
Selling a platinum ring is not the same everywhere. Pawn shops and mail-in services often pay well below true platinum value, and many jewelry stores only offer store credit. Here is how South Bay Coin compares on what affects your payout.

What Our Platinum Sellers Say
"I inherited my mother's platinum engagement ring and had no idea what it was worth. They tested it while I watched and paid me on the spot. The most honest jewelry buyer I have dealt with in Los Angeles."
"Sold my old platinum wedding band here. They weighed it, walked me through how the offer was built, and beat the pawn shop down the street by a wide margin. Quick, respectful, and no pressure at all."
"Brought in a platinum ring with three diamonds. They priced the metal and each stone separately and walked me through every number. I left with more cash than two other buyers had quoted."
"Four decades in the same spot says everything. The team knew platinum cold, tested my ring in minutes, and paid same-day. Highly recommend for anyone in the South Bay."
Common Questions About Selling a Platinum Ring
Your platinum ring's value is based on its weight in grams, its purity (usually 95 percent for PT950), and any diamonds or gemstones. We weigh and test your ring in front of you and explain how each factor shapes the offer, so you understand exactly what you are being paid for.
Genuine platinum rings are typically stamped PLAT, PT, PT950, PT900, or 950 inside the band. Platinum also feels noticeably heavier than white gold or silver of the same size. At our Lawndale showroom we test purity on-site, so you get a definitive answer before any offer.
South Bay Coin buys platinum rings in person at 16916 Hawthorne Blvd in Lawndale, minutes from Torrance, Redondo Beach, and the wider South Bay. Walk-ins are welcome six days a week, and you receive a free evaluation and same-day cash without mailing your ring anywhere.
Platinum and gold each have their own market, and a platinum ring is valued on its own metal rather than on gold's rate. Even though platinum is rarer, the two metals do not move together. We evaluate a platinum ring strictly on its platinum content, purity, and any diamonds, never on gold's value.
No appraisal or certificate is required to sell your platinum ring at South Bay Coin. Our GIA-trained buyers evaluate the metal and stones for free, on the spot. If you do have paperwork or a diamond grading report, bring it, since documentation can support a higher offer.
Yes. We grade and price diamonds and colored gemstones separately from the platinum, so you are paid for both the metal and the stones. For engagement and anniversary rings, the diamonds often add the most value, which is why we never simply melt a stone-set ring.
Absolutely. Bent shanks, cracked bands, worn engravings, and lone settings all still hold their platinum content. Because we buy for the weight and purity of the metal, condition rarely lowers your offer the way it would at a typical resale shop here in Los Angeles.
We use non-destructive methods, including an XRF analyzer (and acid testing when needed), to confirm whether your ring is PT950, PT900, or another fineness. The process takes only minutes, happens while you watch, and never damages your ring, even with delicate vintage pieces.
A plain platinum wedding band typically weighs five to twelve grams, and the offer depends on that weight, the purity, and current market conditions. Heavier men's bands and stone-set rings are worth more. Bring yours to our Lawndale showroom for a free, on-the-spot evaluation and we will explain the full breakdown.
Platinum demand from jewelry and industry keeps the market active. If you have a ring you no longer wear, turning it into cash now means you stop holding an asset that is just sitting in a drawer. Visit our Lawndale showroom during business hours for a free, no-obligation evaluation.
