For your consideration is this interesting pendant. It looks Native American Indian in origin and has a large moss agate. The sterling has a nice cut out and applied ball design. I can not find a mark. It has tested and is guaranteed as sterling silver.
It measures 2 inches by 1 and 1/4 inches across the widest points of the piece and including the bail.
It is in excellent functioning condition but does have a very uneven patina.
