Sell a Platinum Ring in Los Angeles for Cash Today
Platinum ring buyers in the South Bay since 1980. Bring a wedding band, a solitaire or an inherited piece to our Lawndale counter, watch it weighed and tested, and leave with cash on the same visit.
Where to Sell a Platinum Ring in Los Angeles
Before anyone can sell a platinum ring in Los Angeles for what it is worth, someone has to identify the metal correctly. Platinum, palladium and white gold look nearly identical across a counter, and a ring read as white gold is paid for as white gold. South Bay Coin has tested and bought precious metals at 16916 Hawthorne Blvd in Lawndale since 1980, and platinum rings cross this counter every week.
Older rings are where offers go wrong most often. A ring made before the 1970s may be stamped IRIDPLAT, 10% IRID PLAT or 900 PLAT instead of PT950, and a buyer who only recognizes the modern mark can talk himself out of the whole piece. We read the mark, test the metal, and tell you what the ring is before we quote it. If it turns out to be a signed or period piece, we say so, because a designer or estate ring is sometimes worth more assembled than melted.
Every ring is weighed and quoted on its own rather than averaged into a pile, and any diamonds or colored stones are assessed apart from the metal. There is no mailing, no consignment window and no waiting on a check. Walk in from Torrance, Redondo Beach or anywhere else in the South Bay, ask how the number was built, and take the ring home again if this is not the right day for it. We buy platinum jewelry, coins and bars in the same visit.

How Much Is a Platinum Ring Worth?
Three things set the number: the weight of the ring in grams, the fineness of the platinum, and the platinum market on the day you sell. The part most sellers get wrong is weight. Most of the metal in a ring sits in the shank, not in the head, so a wide comfort-fit band can carry several times the platinum of a delicate solitaire mounting that looks far more impressive in the box. Two rings that seem comparable on a hand can be very different on a scale.
Fineness is the second number, and platinum is written in parts per thousand rather than karats. A ring at 950 carries 950 parts pure platinum, a 900 ring carries 900, and the balance is a hardening metal such as iridium, ruthenium or cobalt that is part of the alloy and part of what gets measured. We confirm the fineness at the counter instead of taking the stamp at face value, because stamps get worn flat, and because sizing work sometimes leaves metal in the shank that the original maker never put there.
Stones are the third piece, and they are assessed apart from the platinum. Diamonds, sapphires and other colored stones in a mounting are looked at as stones, not melted into the metal figure. When a ring is worth more assembled than it is as metal, which happens with period settings and recognizable makers, we say so before quoting, and you can decide which route you want.
What PT950, PLAT and IRIDPLAT Mean on a Ring
Platinum has the oldest and most varied mark set in the jewelry trade, and rings are where all of it shows up. Under the Federal Trade Commission jewelry guides, a ring marked simply platinum, PLAT or PT with no number should be at least 950 parts pure platinum. A ring at 900 or 850 states its own fineness, as 900 Plat or 850 Pt. Alloys that are mostly platinum group metals can be marked by naming each one, in the style of 600 Pt. 350 Ir. Below 500 parts pure platinum, the word should not appear on the ring at all.
That is why the old marks matter here. IRIDPLAT, 10% IRID PLAT and 900 PLAT 100 IRID all describe the same thing: 900 parts platinum hardened with 100 parts iridium, the standard American ring alloy for decades, and the mark you will find inside plenty of Art Deco and mid-century bands, Tiffany pieces included. It is platinum, it is bought as platinum, and a seller who reads it as a brand name or a plating code is being talked out of real money.
The wartime gap is worth knowing too. In 1942 the United States government declared platinum a strategic metal and kept it out of civilian jewelry until the war ended, so white rings from those years are often palladium or white gold standing in for it. Those rings are not worthless, they are simply a different metal, and a white gold ring is bought here on the same visit as any other gold jewelry. Unmarked and worn-smooth rings get tested rather than turned away.
Platinum Rings We Buy for Cash in Los Angeles
One ring or a whole box, marked or unmarked, stone set or plain. Every piece is weighed, tested and quoted in front of you at our Lawndale counter.
Sell Platinum Wedding Bands
Plain, milgrain, hammered and comfort-fit bands, single or as a pair. Wide men's bands carry the most metal of any ring we see, and engraving does not reduce the offer.
Sell Platinum Engagement Rings
Solitaires, halos, three-stone and pave mountings. The platinum is weighed and the diamonds are looked at separately, so neither side of the ring is quietly absorbed into the other.
Sell Vintage and Art Deco Platinum Rings
Edwardian filigree, Deco geometry, hand engraving and old mine cuts. Maker marks and original construction can lift a ring well past what the metal alone would return.
Sell Broken or Unmarked Platinum Rings
Cracked shanks, empty heads, cut-off bands and rings with no stamp at all. Damage does not remove the metal, and an unmarked ring is tested rather than refused.

Get Paid Cash the Same Visit
Accept and you are paid in cash or by check before you leave. Decline and the ring goes back in your pocket. Bring a valid photo ID either way.

Reviews from Los Angeles Platinum and Jewelry Sellers
Questions About Selling a Platinum Ring in Los Angeles
How much is my platinum ring worth?
A platinum ring is valued on three things: its weight in grams, its fineness in parts per thousand (usually 950 or 900), and the platinum market that day. Any diamonds are assessed separately. Because most of the metal sits in the shank, a plain wide band often outweighs a fancier mounting.
How can I tell if my ring is really platinum?
Check inside the shank for PLAT, PT, PT950, 950, 900 Plat or IRIDPLAT. Platinum also feels heavier than a white gold ring of the same size and does not fade to yellow at the edges. Marks wear away, though, so bring the ring in and we will confirm the metal at the counter.
What does PT950 mean inside a ring?
PT950 means 950 parts pure platinum out of a thousand, with the remaining 50 parts a hardening metal. It is the most common fineness for American platinum rings. A ring marked only platinum or PLAT, with no number, should also be at least 950 parts pure under the FTC jewelry guides.
What does IRIDPLAT mean on an old ring?
IRIDPLAT, 10% IRID PLAT and 900 PLAT 100 IRID all mean the same alloy: 900 parts platinum hardened with 100 parts iridium. It was the standard ring alloy in the United States for decades, including at Tiffany. It is genuine platinum and we buy it as platinum, not as scrap white metal.
Where can I sell a platinum ring near me in Los Angeles?
South Bay Coin buys platinum rings in person at 16916 Hawthorne Blvd in Lawndale, minutes from Torrance, Redondo Beach, Hawthorne and Manhattan Beach. Walk in six days a week for a free evaluation and same-day cash. Nothing is mailed away, nothing is held overnight, and no appointment is required.
Can I sell a platinum engagement ring with the diamond still in it?
Yes. Bring the ring exactly as it is. We weigh the platinum mounting and look at the center and accent stones on their own, so both parts of the ring are accounted for. If you would rather keep the diamond, tell us at the counter before we quote the piece.
Do you buy platinum rings with no stamp inside?
We do. Marks wear smooth with decades of wear, and some early rings were never stamped at all. An unmarked ring is tested at the counter rather than turned away or assumed to be silver, which is what happens to a lot of genuine platinum at buyers who work from the stamp alone.
Will you buy a bent, worn or broken platinum ring?
Yes. Cracked shanks, bent bands, empty settings and rings cut off in an emergency room are all bought. The platinum is still there, and the offer is built on metal and stones rather than on how presentable the ring looks. Repair costs are not deducted from your number.
What paperwork do I need to sell a platinum ring?
Just a valid photo ID, which California requires for precious metal purchases. No certificate or prior valuation is needed. If you happen to have a diamond grading report or the original receipt, bring it, since documentation on a stone can support a stronger offer on the assembled ring.
Do I need an appointment to sell a platinum ring in Los Angeles?
No appointment is needed. Walk into our Lawndale showroom Monday through Friday from 10 AM to 5 PM, or Saturday from 10 AM to 3 PM. We are closed Sunday. Most single-ring visits take about fifteen minutes, from the first weighing to cash in hand.
