Why Los Angeles Trusts Us to Buy Platinum Necklaces

When you want to sell a platinum necklace in Los Angeles, you want a buyer who actually knows the metal. South Bay Coin has weighed, tested, and paid cash for precious metals since 1980, and our GIA-trained staff evaluates every platinum piece in front of you using calibrated scales and professional testing.

Platinum is denser and rarer than gold, so an accurate weight and purity reading matters enormously to your payout. We identify PT950, PT900, and PT999 hallmarks, test unmarked pieces, and pay for the true metal content rather than a lowball flat rate. Many clients also sell gold jewelry in Los Angeles with us on the same visit.

There is no shipping, no insurance risk, and no waiting for a mailed check. You walk into our Lawndale showroom, watch the evaluation happen, and leave with cash in hand the same day. Walk-ins from across the South Bay are always welcome.

How We Value Your Platinum Necklace

Every platinum necklace we buy is priced on three things: weight, purity, and the live platinum spot price. We weigh your chain or pendant on a state-certified scale, confirm the purity from the hallmark, and calculate the melt value against the market rate that day, so the offer reflects exactly what your metal is worth.

Purity drives the number. PT950 contains 95% pure platinum, the standard for fine necklaces, while PT900 holds 90%. Because platinum is so dense, even a modest-looking chain can carry real weight and value. If your piece also holds diamonds or sapphires, we evaluate the stones separately, the same way we do when customers get cash for gold and precious metals here.

Designer and signed pieces from houses like Tiffany or Cartier can be worth well beyond melt, and we recognize that premium rather than scrapping a collectible. Bring any boxes or certificates you still have, since documentation can lift your final Los Angeles cash offer.

What Platinum We Buy for Cash

From a single chain to an entire jewelry box, we pay for platinum in every form across the South Bay.

Platinum Chains & Necklaces

Curb, rope, box, and Figaro chains in PT950 or PT900, whether solid or broken. Clasps, snapped links, and tangled chains are all paid at full metal value.

Pendants & Lockets

Platinum pendants, lockets, and necklace charms, including pieces set with diamonds or colored gemstones that we appraise alongside the precious metal content.

Designer & Signed Pieces

Signed platinum necklaces from Tiffany, Cartier, Van Cleef, and other houses, valued for both their craftsmanship and their metal, not simply melted for scrap.

Estate & Inherited Platinum

Inherited collections, estate necklaces, and vintage platinum jewelry. Bring the full lot and we will sort, test, and weigh every piece on the spot.

How We Compare

South Bay Coin vs. Other Platinum Buyers

Not every buyer treats platinum fairly. Pawn shops often pay a fraction of melt, jewelry stores may only offer store credit, and mail-in services hold your necklace for days. Here is how South Bay Coin compares for Los Angeles sellers.

"I inherited a heavy platinum chain and had no idea what it was worth. South Bay Coin tested it right in front of me and paid more than two other shops quoted. Honest people."

Linda M. · Torrance, CA

"Sold a platinum and diamond necklace here. They appraised the stones separately instead of just melting everything down. Walked out with cash the same afternoon."

David R. · Redondo Beach, CA

"Drove in from Long Beach with a few old platinum pieces. No pressure, a clear explanation of the spot price, and a fair offer. I will be back with the rest."

Sophia T. · Long Beach, CA

"Forty-plus years in business shows. They recognized my necklace as a designer piece and paid for it as one, not as scrap metal. Highly recommend for the South Bay."

Common Questions About Selling a Platinum Necklace

A platinum necklace's value depends on its weight, purity, and the day's platinum spot price. Most fine necklaces are stamped PT950, meaning 95% pure platinum. Heavier chains carry more value, and designer or stone-set pieces can be worth well beyond their melt value at South Bay Coin.

Look for a hallmark stamped near the clasp, such as PLAT, PT, PT950, or PT900. Platinum also feels noticeably heavier than silver or white gold of the same size. If your necklace is unmarked, our Lawndale team can test it for free and confirm the metal before making any offer.

PT950 means your necklace is 95% pure platinum, with the remaining 5% usually ruthenium or iridium added for durability. It is the most common standard for fine platinum jewelry in the United States. PT900 indicates 90% purity. Higher purity means more pure platinum and a higher cash offer.

In 2026, gold has traded higher per ounce than platinum, even though platinum is rarer. Prices for both metals change daily, so your necklace's value is calculated against the live spot price the day you sell. We show you the current Los Angeles rate before quoting your offer.

South Bay Coin buys platinum necklaces at our Lawndale showroom at 16916 Hawthorne Blvd, serving Torrance, Redondo Beach, Manhattan Beach, and all of Los Angeles County. We have paid cash for precious metals since 1980. Walk in, call (310) 363-7808, or text a photo for a quick estimate.

For its metal value, condition does not matter. A broken, kinked, or worn platinum necklace is worth the same as a perfect one because we pay for weight and purity. Condition only matters for designer pieces we may resell intact, where pristine examples can command a higher price.

Yes. We evaluate the platinum and the gemstones separately, so you are paid fairly for both the metal content and any diamonds or colored stones in the setting. Many sellers are surprised that stones add meaningful value rather than being ignored. Bring any grading certificates you still have.

No paperwork is required to sell a platinum necklace for its metal value. However, for designer or signed pieces from houses like Tiffany or Cartier, original boxes, receipts, or certificates can raise the offer because they confirm authenticity. Bring whatever documentation you have to your evaluation.

We weigh your necklace on a certified scale, confirm its purity from the hallmark, and multiply the pure platinum content by the day's spot price. Designer value and gemstones are added on top. The entire calculation happens in front of you at our Lawndale counter, with no hidden fees.

Pawn shops often pay a small fraction of melt value and many jewelers only offer store credit. A dedicated precious metals buyer like South Bay Coin pays live spot value in cash and recognizes designer pieces. Comparing offers locally in Los Angeles almost always favors a specialist buyer.
