What does 923 stamped on diamond bracelet mean?

The "923" stamp on a diamond bracelet typically indicates the metal's purity, specifically that the bracelet is made of 92.3% pure silver or another precious metal alloy. This is often associated with sterling silver, which is commonly marked as 925, but the "923" may suggest a slightly different alloy composition. Additionally, the stamp could also relate to a specific manufacturer's code or design. Always verify with a jeweler for accurate identification.
