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. However, this is not true.92.5% is not a standard gold purity value, and it does not correspond to any commonly used karat number.f there are any karat markings on the piece, they can also indicate the karat of the plating. For example, a mark that reads â22Kâ likely means that the top layer of the jewelry is 22-karat gold. This gold bracelet is actually plated with 18K gold.
