Common questions
How is the 18K gold price per gram worked out?
Take the gold spot price per troy ounce, divide by 31.1035 to get the price per gram of pure gold, then multiply by 75.0%, the share of pure gold in 18K gold.
Why will a buyer pay less than this for my 18K?
This is the melt value at spot. Buyers pay a percentage of it to cover testing, refining and their costs. Use the calculator to set the percentage a buyer offers and see what you would get.
How can I tell if my item is 18K gold?
Look for a 750 stamp or "18K" on the clasp, inside a ring band, or on an earring post. If there's no stamp, a buyer can test it. See the stamp decoder for other marks.
