These spinners are sometimes called fobs, worn on a man's watch chain. This one circa 1885, is n nice condition. One side agate add the other bloodstone. Clearly marked 375 9ct English Rose Gold. Bloodstone doesn't have much red in it but it is there and much sought after by Victorians who believed it purified the blood. With the ring measures 1 3/8 inches long, set in a nice framework and spins well! This means can wear it with either side showing. There is a name for the agate carved to show the edges but can't recall.
