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.
In the U.S., solid gold jewelry is marked with the purity and the hallmark (trademark) of the maker. So, for example, my wedding ring is marked 14K FG which means it is 14 karat gold, made by Frederick Goldman, Inc.The maker's hallmark can usually be found by searching the US Patent and Trademark Office's trademark database (but the search will probably be tedious).here is, however, an exception, and that is that GF is the standard abbreviation for gold filled which means it is a cheaper metal core coated with gold on the outside. In other words, it is not solid gold.
