How do I calculate the value of gold?
Convert the weight to troy ounces (grams ? 31.1035), multiply by the karat purity, then multiply by the live gold spot price. The calculators above do this automatically for each karat.

A piece of gold is worth its weight in troy ounces times its purity times the live gold spot price. Everything else - karat stamps, jewelry style, coins versus scrap - is a way of answering those three questions. This hub brings the calculators and guides together in one place.
Start with the calculator for your karat or item, confirm the live spot price, and apply a payout percentage if you are buying or selling. Then use the guides to understand hallmarks, market drivers, and fair offers.

FAQ
Gold questions
What karat of gold is worth the most?
Per gram, higher karats hold more gold: 24K is pure, then 22K, 18K, 14K, and 10K. A heavier low-karat piece can still be worth more than a light high-karat one.
Is gold jewelry worth more than its melt value?
Plain or broken jewelry usually sells near melt. Designer, antique, or gem-set pieces can be worth more, so consider an appraisal before scrapping them.
