Gold melt value
calculator.
Melt value is the worth of the gold inside a piece at today’s spot price — its gold weight times the per-gram rate for its karat. It is a floor reference for the metal, and nothing more. It is not a resale offer, a wholesale quote, or a retail price: it excludes diamonds and stones, casting and finishing labour, and margin. Enter a weight and karat below to see the live figure.

Purity · Per Gram
What each karat is worth.
Karat is the share of the alloy that is pure gold. Only that share carries bullion value, so the melt rate scales with purity. These are the live per-gram figures the calculator uses.
| Karat | Pure gold | Purity ratio | Spot $ / gram |
|---|---|---|---|
| 10K | 41.7% | 0.4170 | $56.15 |
| 14K | 58.3% | 0.5830 | $78.50 |
| 18K | 75% | 0.7500 | $100.98 |
| 22K | 91.7% | 0.9170 | $123.47 |
Derived from the Kitco gold ask of $4187.90 per troy ounce (as of June 12, 2026) ÷ 31.1034768 g × alloy purity — the same conversion behind every Clazoire quote.

The Specifics
Melt value, answered straight.
Melt value is the gold content of a piece at the current spot price. Take the gold ask per troy ounce, divide by 31.1034768 grams to get the pure-gold per-gram rate, multiply by the karat's purity to get the per-gram value of that alloy, then multiply by the piece's gold weight in grams. This calculator uses the exact same conversion Clazoire's quote engine uses.
Karat is how much of the alloy is pure gold: 10K is 41.7% gold, 14K is 58.3%, 18K is 75%, and 22K is 91.7%. The rest is other metals with little bullion value. So a gram of 18K gold is worth more in melt than a gram of 10K, because it holds more pure gold. The calculator applies the right purity for the karat you pick.
No. Melt value is the metal only. It excludes diamonds and other stones, casting and finishing labour, and any margin. It is a floor reference for the gold content of a piece, not a resale price, a wholesale quote, or what a buyer would pay at retail.
