African Blood Quartz

Bloodstone (Heliotrope) may be classified as a Jasper or Chalcedony variety of Quartz, and is usually a combination of the two. It is typically defined as a dark green Chalcedony with blood-like spots of Red Jasper or iron oxide inclusions. It occurs as massive formations, ranging from dark green to greenish-blue or greenish-black, and may be translucent to opaque with a waxy, resinous luster.
