What does 10 NV 925 mean on a ring?

The marking "10 NV 925" on a ring indicates that the piece contains 92.5% silver, which is the standard for sterling silver (hence the "925"). The "10 NV" likely refers to a specific manufacturer or designer's mark, with "10" possibly indicating a particular collection or style. This combination suggests that the ring is both made of sterling silver and associated with a specific brand or artisan.
