If your gold piece doesn't have a stamp, that doesn't necessarily mean it's fake. Older pieces of gold may not be stamped because stamping wasn't required in the past.
The Stamp Test: Look for Hallmarks
A piece of gold jewelry is often engraved with a hallmark, which is a stamp that identifies its content and/or manufacturer. Hallmarks usually appear in an inconspicuous place like the inside of a ring. The standard purity scales are based upon karats and millesimal fineness.
It is important to point out that most of the old gold that is out there does not have any hallmarks, so if you already know that the item goes back a few generations then this could explain it. You could also find that it was a one off piece commissioned for someone and the designer has not put those marks on.

Look at the Hallmarks – Jewelry hallmarks are markings on the post, band, or clasp that indicate the piece's country of origin or its metal content.
