This beautiful necklace has a rich combination of mother-of-pearl and marcasites in a sterling silver frame. The marcasites line both the cross and the perimeter of the frame, and the MOP makes a striking contrast. The pendant measures 1-1/8 x 3/4 inches (including the bail) and is marked on the back "Sterling" along wih a mark that I can't quite make out. The very fine chain is 15-1/2 inches long, with a jump-ring clasp. I will lightly polish both the pendant and chain before shipping, unless requested otherwise.
