Many people tend to think that the 925 gold stamp means it has 92.5% gold but the “925” is only the hallmark for sterling silver. When 925 is stamped on gold, that almost always means that it is Gold Plated Sterling Silver. The thickness of the gold layer has to be at least 2.5 microns.
Silver is rated by a grading system, whereas gold is rated by purity of the gold, known as Karat.
