Antique Victorian gold tone black and white bullseye agate triple cabochon brooch, slight hairline cracking

Classic Victorian brooch with triple bullseye agate cabochons set in gold metal. These are highly collectable pieces and these cabochons are nicely selected with the thin regular white stripe of the agate around the edge of each. Brooches of this kind were often gold filled, when not solid gold. I actually have not had this tested at all as yet, so don't know if it is gold or not. The brooch is in good vintage condition apart from the minor crazing / hairline cracks to the agate, particularly on two of the stones as pictured.
