Offering for sale a fabulous brooch or pin with sparkly marcasites. In the center is a large black stone, possibly black onyx, set in sterling silver. Surrounding this are ornate swirls and open metalwork, with the sterling silver decorated with beautiful marcasites. It is a wonderful size, measuring 1 & 15/16" long and 15/16" tall. It is in very good condition, I do not think there are any missing stones, if there are they are insignificant, it is hard to tell with marcasites set on sterling. I did not polish this sterling for the photos.
