The number 688 on jewelry typically indicates the metal's purity, specifically referring to an alloy that is 68.8% pure silver. The remaining percentage usually consists of other metals, which can enhance durability and appearance. This marking is not as common as others like 925 for sterling silver but signifies a specific standard of quality in silver jewelry. Always verify with a trusted jeweler for the exact meaning, as markings can vary.
