These marks, which can be found inside, at the clasp, or on the back, depending on the type of jewelry, are meant to tell you how pure the gold used in that item is, or if it contains any gold at all.

What Does The Stamp 750 Mean On Jewelry?

It is considered to be one of the internationally recognized fineness marks. The fineness of an alloy is a numerical representation of its gold content in parts per thousand. The gold content of an alloy is measured in parts per 24. The fineness of 750 indicates that the gold is 18 karat, as demonstrated by the presence of a 750 gold stamp.
Now, carat is a different way of measuring purity. For example, for 999.9 or 24-karat gold, fineness is almost pure gold. Moreover, what other metals are alloyed with gold is determined by neither fineness nor karat.

It’s safe to say that jewelry items stamped with 720 are pure and real. There are, however, counterfeits in circulation, but they are rare.
