What does 18K on a ring mean?
1 Answer

The mark 18K on a ring stands for 18-karat gold. 18-karat signifies that the ring is 75% pure gold and 25% other metals, such as copper, zinc or nickel. The additional metals strengthen the ring, making it more durable. Shop a range of expertly vetted 18-karat jewelry on 1stDibs.
