What does 623 mean on jewerly?

Answer 1

The marking "623" on jewelry typically indicates that the piece is made of 62.3% pure silver, which corresponds to a silver content of 15 out of 24 parts. This is similar to the more common sterling silver marking of "925," which signifies 92.5% silver. The "623" mark is less common and may represent an alternative silver alloy or standard used in specific regions or manufacturers. Always check with a jeweler for precise identification and context.
