A semiprecious stone composed of dark green Chalcedony with flecks of red Jasper that were thought to resemble drops of blood. Bloodstones, when submerged in water, give a reddish reflection. These stones are found in Asia, the Hebrides Islands of Scotland, Ethiopia, Egypt, India, and western Europe. Bloodstones were not commonly used in ancient times although occasional cylinder seals have been found (Odgen 1982). During the Middle Ages, bloodstones were used in sculptures to represent flagellation. Bloodstones are currently used as gemstones in jewelry.
