This is a very unique pin made of fronds of pearls that have been threaded on wire with a center silver tone "stem" that is set with marcasites.  Attention to detail makes this a very artful piece of vintage jewelry in the natural flowing lines of the pearls. The entire pin measures 3 7/8" long x 1 1/4" wide. Although of unknown origin, the back is set with a safety pin style C-clasp that was used more often in Europe than in the US.   SORRY! THIS ITEM HAS ALREADY BEEN SOLD.
