goldring18k

An 18k gold ring is a piece of jewelry made from 75% pure gold and 25% other metals. The "k" stands for karat, which is a unit of measurement for the purity of gold. In an 18k gold ring, 18 out of 24 parts are gold, making it 75% pure gold. The remaining 25% is typically made up of other metals such as copper, silver, or zinc, which are added to strengthen the gold and enhance its durability.
