What does 824 stamped on gold mean?

Answer 1

The number "824" stamped on gold indicates its purity level, specifically that the gold is 82.4% pure. This is equivalent to 20 karats, as pure gold is 24 karats. The remaining percentage consists of other metals alloyed with the gold, which can enhance its durability and alter its color. Thus, 824 gold is a high-quality alloy commonly used in jewelry and other decorative items.
