The number "545" on a ring typically refers to the gold purity standard, indicating that the ring is made of 545 parts per 1,000 of pure gold. This means the ring is 54.5% gold, often corresponding to 14-karat gold. The remaining percentage consists of other metals, which are added to enhance durability and alter color. Always consider context, as "545" might have other meanings in different scenarios.
