Updated every 60 seconds during market hoursWhat 18K Gold Really Means When You Sell
18K gold means 18 of 24 parts are pure gold, or 75% fine, which is why so many pieces carry a 750 stamp. The remaining quarter is alloy metal (copper and silver for yellow, palladium or nickel for white, extra copper for rose) added for durability. All three colors of 18K share the same 75% gold content, so they are valued the same way by weight.
Because 18K holds more pure gold than 14K (about 58.3%) or 10K, it carries a higher melt value gram for gram. We confirm purity with electronic XRF analysis, acid testing, and hallmark inspection, looking for 18K, 18kt, 750, or 0.750 marks on the clasp, inner band, or post. If a piece is unstamped, our testing settles it at no charge and no obligation.
The metal is only part of the story. Designer and signed 18K from houses like Cartier, Bvlgari, Van Cleef and Arpels, and David Yurman can carry value above its gold content thanks to craftsmanship and collector demand. We evaluate both the melt and the secondary-market worth, then pay whichever is higher. The same expertise carries over when you sell gold coins with numismatic value.

What Our Customers Say
Common Questions About Selling 18K Gold Jewelry
18K gold means the piece is 75% pure gold, stamped 750 in many markets. The remaining 25% is alloy metals like copper, silver, or palladium added for strength. Because 18K carries more pure gold than 14K or 10K, it holds a higher melt value gram for gram when you sell.
We verify 18K gold using electronic XRF analysis, acid testing, and hallmark inspection. Genuine pieces usually carry an 18K, 18kt, 750, or 0.750 stamp on the clasp or inner band. Testing is free, performed in front of you, and confirms the true purity before we ever discuss an offer.
Gold has traded near historic highs through 2026, so many Los Angeles sellers are bringing in 18K pieces now. Because 18K is 75% pure, its value tracks the gold market closely. Walk in for a free, no-obligation appraisal and we will show you exactly what your jewelry is worth today.
Yes. Brands such as Cartier, Bvlgari, Van Cleef and Arpels, David Yurman, and Tiffany often command value above gold content because of craftsmanship and collector demand. We evaluate every 18K designer piece for both its metal weight and secondary-market value, then pay whichever figure is higher for you.
The difference is purity. 18K contains 75% pure gold while 14K contains about 58.3%, so an 18K piece of equal weight carries noticeably more gold. That higher gold content means 18K typically returns more when sold. We buy every karat, weigh each separately, and price by exact purity.
Absolutely. Broken clasps, snapped 18K chains, single earrings, bent rings, and tangled pieces all hold full gold value based on weight and purity. Condition never reduces the metal content. Bring any 18K jewelry, complete or damaged, and we will weigh and evaluate every gram for cash.
South Bay Coin sits at 16916 Hawthorne Blvd in Lawndale, minutes from Torrance, Redondo Beach, and Manhattan Beach. As a licensed California gold buyer with an in-house refinery, we serve sellers across the South Bay and greater Los Angeles County. Walk in, no appointment needed, for a free 18K appraisal.
Yes. 18K yellow, white, and rose gold all contain the same 75% pure gold. Only the alloy mix changes the color: palladium or nickel for white, extra copper for rose. We test and pay on the actual gold content, so all three 18K colors are valued the same way.
No appointment is required. Walk into our Lawndale showroom during business hours and our appraisers will test and weigh your 18K jewelry on the spot. You can also text photos to (310) 363-2697 for a preliminary estimate before you visit. Most in-store appraisals take about fifteen minutes.
Pawn shops resell your 18K jewelry to a refiner and keep a markup, so their offers run lower. South Bay Coin owns the refinery, removing that middle step entirely. We have bought gold in Lawndale since 1980, test in front of you, and pay at the top of the market.
