Sell Luxury Jewelry for the Highest Price in Los Angeles
South Bay Coin has been a trusted luxury jewelry buyer in Los Angeles for more than 45 years. Bring in your designer, diamond, and estate pieces for a discreet, no-obligation appraisal and leave with cash the same day.
The Trusted Place to Sell Luxury Jewelry in Los Angeles
South Bay Coin is the trusted place to sell luxury jewelry in Los Angeles, serving discerning clients from Beverly Hills to the South Bay since 1980. For more than 45 years our GIA-trained team has purchased designer pieces, diamond jewelry, and fine gold and platinum from families, collectors, and estates across Los Angeles County.
Selling a high-end piece is different from selling scrap. A signed Cartier bracelet, a Tiffany solitaire, or a Van Cleef necklace carries value far beyond its metal and stones, and most buyers ignore that premium entirely. We recognize brand, craftsmanship, condition, and current resale demand, which is why our clients consistently walk away with more than pawn shops and quick-cash storefronts offer.
Every appraisal is private, unhurried, and complimentary. We examine, test, and authenticate each piece in front of you and explain exactly how we arrive at our offer, with no pressure to accept. Whether you are ready to sell your diamonds, release an inherited collection, or sell designer jewelry, you are treated with the same discretion and respect.
As a licensed, bonded, and insured California dealer with a permanent storefront in Lawndale, we offer something mail-in and online buyers cannot: a real place, real experts, and real cash the same day. There is no shipping your treasures to a stranger and waiting weeks for a check.

How We Value Your Designer and Fine Jewelry
Luxury jewelry is valued on far more than weight. Our gemologists begin with the maker. Pieces signed by Cartier, Tiffany & Co., Van Cleef & Arpels, Bulgari, Harry Winston, David Yurman, and Chopard command a premium because the brand, the design, and the provenance carry their own market. We identify hallmarks, signatures, and serial numbers to confirm authenticity.
Next we evaluate the gemstones. Diamonds are graded on the 4Cs (cut, color, clarity, and carat weight), and colored stones such as sapphires, emeralds, and rubies are assessed for origin, treatment, and quality. A certified center stone, especially one graded by the GIA, adds confidence and value. We read existing certificates and grade both loose and mounted stones on site.
Finally we weigh the metal, the craftsmanship, the era, and current demand. Platinum and high-karat gold settings, intricate handwork, and complete original boxes and papers all influence the offer. Estate and vintage pieces from a recognizable design period are often worth more intact than melted. Because we sell to a network of collectors and dealers rather than a refiner alone, we can pay for the piece, not just the materials. If you also own a fine timepiece, our luxury watch buyers can appraise it in the same visit.

What Our Clients Say
Common Questions About Selling Luxury Jewelry
For the most money, sell luxury jewelry directly to a buyer who understands brand value, not just metal weight. South Bay Coin pays for the designer, the diamonds, and the craftsmanship, and sells to a collector network rather than a refiner. That is why our offers regularly beat pawn shops and other Los Angeles buyers.
We value designer jewelry by the maker first, then the materials. Signatures from Cartier, Tiffany, or Van Cleef carry a premium, so we confirm hallmarks and serial numbers. We then grade the diamonds and gemstones, assess the metal and craftsmanship, and factor in condition, original boxes, papers, and current resale demand.
Yes. Original boxes, certificates, and receipts add value and speed, but they are not required. Our GIA-trained gemologists authenticate and grade your pieces in house, so you can sell luxury jewelry confidently even when the paperwork is long gone. Bring whatever you have and we will handle the rest.
We buy signed pieces from Cartier, Tiffany & Co., Van Cleef & Arpels, Bulgari, Harry Winston, David Yurman, Chopard, Mikimoto, and many other prestige houses. We also purchase unsigned fine and estate jewelry crafted in high-karat gold or platinum. If you are unsure who made your piece, bring it in for a free appraisal.
It depends on your timeline. Consignment and auction can sometimes reach a higher final price, but they take weeks or months and charge commissions and fees. Selling directly to South Bay Coin gives you a firm cash offer the same day with no fees, no waiting, and no uncertainty about whether your piece sells.
No appointment is necessary. You are welcome to walk into our Lawndale showroom during business hours, and most appraisals take only a few minutes. If you prefer a private, dedicated session for a larger collection, call (310) 363-7808 ahead and we will set aside time for you.
Our gemologists inspect hallmarks, maker's marks, and serial numbers under magnification, then test metals and examine gemstones with professional tools. Diamonds are graded on the 4Cs, and we verify any existing certificates. Everything is done in front of you in the showroom, so you see exactly how authenticity and value are confirmed.
Absolutely. Inherited and estate jewelry is one of our specialties. We handle entire collections with discretion, identify pieces that are worth more intact than melted, and explain the value of each item clearly. Many clients are surprised to learn what an old family piece is actually worth in today's market.
Yes. Damaged or incomplete designer and fine jewelry still holds real value in its gold, platinum, diamonds, and brand. We evaluate every piece on its own merits, whether it is missing a stone, has a broken clasp, or is simply worn. Bring it in and we will make a fair offer.
A pawn shop typically pays melt value and overlooks the designer name entirely. South Bay Coin is a licensed buyer with GIA-trained gemologists who recognize brand, gemstone quality, and craftsmanship. We pay for the full piece, not just the metal, which is why our clients across Los Angeles consistently receive higher offers.
