What is 10K gold?
10-karat gold is an alloy containing approximately 41.7% pure gold and 58.3% other metals. The added metals make it relatively durable, which is why 10K is often used in everyday rings, chains and bracelets in the United States.
10K and 417 hallmarks
An item may be marked “10K,” “10KT” or “417.” The number 417 represents approximately 417 parts of gold per thousand. A hallmark is useful evidence, but wear, repairs, plating and counterfeit marks can make professional testing necessary.
