925 is a standard sign used to mark sterling silver, and the meaning of the stamp is that the silver content in the piece is 92.5% (i.e., the remaining 7.5% is comprised of other elements). Perhaps because the âgoldâ jewelry you are looking at is not actually made of gold.
Many people think that a stamp reading â925â on gold jewelry means that the piece contains 925/1000 gold, or in other words, it has 92.5% gold content.

This is the name used to denote silver jewelry covered with a thin layer of gold.
