Understanding Metal Value
Karat stamps, melt value, and the collector premium
When you inherit gold or silver jewelry, the first question is usually: what is this worth? The answer depends on whether the piece has value only for its metal content — its melt value — or whether it carries a premium above melt because of who made it, when it was made, or how it was designed. Understanding the difference can mean hundreds or thousands of dollars.
Understanding karat stamps
The karat stamp tells you exactly how much gold is in a piece. Pure gold is 24 karats, but pure gold is too soft for most jewelry, so it is alloyed with other metals. The common purities are:
10K = 41.7% gold. The minimum karat that can be legally sold as gold in the United States. Common in class rings and affordable jewelry.
14K = 58.3% gold. The most common purity in American jewelry. A good balance of durability and gold content.
18K = 75% gold. Common in fine and designer jewelry. Richer color, softer metal.
22K = 91.7% gold. Common in Asian and Middle Eastern jewelry. Very rich yellow color.
24K = 99.9% gold. Pure gold. Rare in Western jewelry because it is extremely soft.
European jewelry often uses a different numbering system based on parts per thousand: 375 (9K), 585 (14K), 750 (18K), 916 (22K). Platinum is marked PT, PLAT, or 950. Sterling silver is marked 925 or Sterling.
Calculating melt value
Melt value is straightforward: weight multiplied by purity multiplied by the current spot price of the metal. As of 2026, gold is approximately $2,000+ per troy ounce and silver is approximately $25+ per troy ounce. A 10-gram 14K gold chain contains about 5.83 grams of pure gold — roughly 0.187 troy ounces — worth approximately $375 at $2,000 per ounce. Dealers typically pay 70-90% of calculated melt value.
Melt value is the floor — the minimum a piece is worth. For many inherited pieces, the actual value is considerably higher.
When to sell for melt
Some pieces genuinely have no value above their metal content. Plain wedding bands without design significance or maker marks. Damaged pieces with no maker attribution. Broken chains that cannot be economically repaired. Single earrings without their pair. Small, simple pieces with no collector interest. For these items, melt value is the right benchmark, and a reputable gold buyer will give you a fair price based on weight and purity.
When NOT to sell for melt
This is where the real money is — and where most people make costly mistakes. Never sell for melt if the piece falls into any of these categories:
Signed or designer pieces. Jewelry bearing a maker's mark from a known designer or house can be worth multiples of its melt value. The premium above melt can be enormous — a signed bracelet worth $500 in gold might sell for $5,000 or more to a collector.
Period pieces. Art Deco, Victorian, Edwardian, Art Nouveau, and other period jewelry is collected for its design and craftsmanship, not its metal weight. These pieces are worth more intact and should never be melted.
Watches. Never sell a gold watch for melt value. Even a non-running vintage watch is almost always worth far more than its gold content. A gold watch case melted down is irreversible and almost certainly a financial loss.
Unique or unusual designs. One-of-a-kind pieces, custom work, and unusual forms attract collector interest that exceeds metal value.
Pieces with significant gemstones. Stones add value that melt buyers typically ignore or undervalue. Have gemstones evaluated separately before considering any sale.
Gold-filled and gold-plated
Not everything that looks like gold is solid gold. Gold-filled (stamped GF) means a thick layer of gold has been mechanically bonded over a base metal. It contains some gold — typically about 5% of the total weight — but much less than solid gold. Gold-plated (stamped GP) has a very thin layer of gold applied through electroplating, with negligible metal value. "Rolled gold" is similar to gold-filled. These distinctions matter enormously: a piece that looks identical to solid gold may be worth a fraction of what you expect.
Testing and verification
If stamps are missing, worn, or unclear, metal content can be verified through several methods. Acid testing is the traditional approach — a small mark is made on a touchstone and tested with acid solutions of different strengths. Electronic testers provide a quick reading of metal purity. XRF (X-ray fluorescence) analysis gives precise readings without damaging the piece. In many cases, specialists can confirm metal content from photos by identifying stamps, hallmarks, and construction characteristics that indicate the metal type.
