A vintage sterling silver and black gemstone fish pin signed "M.N.". This fish is very unique having a stamped design that makes a texture in the sterling silver surface that looks like scales. the fish is large and has a single black gemstone for the eye. This stone may be a genuine onyx but we are not certain. The back of this fish has the signature "M.N. Sterling" and a pin with locking "C" clasp that holds great. The fish measures 1 1/2" long by 1 5/8" wide and is in fine overall condition having no wear or scratching to the sterling silver metal surface.
