What does a number 835 mean on a gold ring?

The number 835 on a gold ring indicates that the ring is made of 83.5% gold, which is equivalent to 20 karats. This means that the gold content is high, but not as pure as 24-karat gold, which is 99.9% gold. The remaining percentage typically consists of other metals that enhance durability and alter the color of the gold. Such markings are common in jewelry to denote the quality and purity of the gold used.
