Vintage agate circle pin with bloodstone and striped agate stones set in sterling silver claws. Slate back with c clasp. Marked "Made in England" and "Silver" on the back. Center of the pin is a sterling piece also. All sterling claws are in good condition. There is one small flaw on the striped agate as shown in photo. The simple c clasp probably dates it to the earlier part of the 20th c.
