Gold Guides

Short, plain-language explainers to help you understand what your gold is and what it's worth.

How to find your karat (hallmark markings)

Most gold is stamped with a tiny number that tells you its purity. Look on the clasp, inside a ring band, or on the back of a pendant:

Don't see a stamp? Use the "I don't know my karat" flow in any calculator, or estimate with a custom purity.

Selling scrap gold

Buyers pay for the pure gold content, minus a margin for refining and risk — typically 70–90% of spot. Weigh your items, group by karat, and use the scrap gold calculator to set expectations before you visit a buyer.
