A vintage piece of Mexican sterling silver jewelry by Melecio Rodriguez. This unique pin is composed of a fine 925 sterling silver metal which forms a fish with etched lines that make up the gills and fins. The center body is made up of inlaid abalone shell which mixes well with the sterling silver metal. The back side has a pin and locking "C" clasp as well as the signature "Mexico" and "Sterling 925 Mexico" around the initials "MR" which stand for the designer Melecio Rodriguez who was a master silversmith for the Taxco Mexico company. This item measures 2 3/4" from head to tail fin and 1" from top to bottom. It is in great overall condition having been recently cleaned and polished up.
