How to compare buyer quotes and published payout benchmarks.
What 21K gold is worth
21K gold is 87.50% pure. Its melt value is weight in grams × 0.8750 ÷ 31.1035 × the live gold price per troy ounce. The calculator applies that formula before showing buyer discounts.
Where 21K gold appears
21K jewelry is especially familiar in Middle Eastern markets. Its high gold content gives a rich color, while clasps, solder, stones, and non-gold additions still need to be excluded from melt weight.
Melt value is the negotiating yardstick
Jewelry buyers pay below melt to cover testing, refining, shipping, and margin. Compare every dollar quote with the melt value and get at least three offers before selling.
