Abstract: A tool for stamping symbols on a piece of jewelry is provided having a pliers-type mechanism with two jaws between which the jewelry is placed. One or more rotatable marking wheels in the shape of a gear is placed on the interior of one of the jaws. Each of the marking wheels has a symbol engraved on at least one of its teeth such that when the handle portion of the pliers is squeezed, a symbol is stamped into the jewelry.
