Bloodstones are rocks. In the sense that diamonds and rubies are rocks too; bloodstone is likewise a mineral. The name is relative to the area, much like any other form of matter. In Germany, Hematite is considered to be bloodstone, while Heliotrope is called bluestone instead to differentiate the two. Others argue that Heliotrope is the only true bloodstone. Many mistake Fancy Jasper for bloodstone. Most consider bloodstone to be of two specifically different types of stone; Plasma, and Heliotrope. Bloodstone is green Jasper, with flecks of red iron oxide inside. Fancy Jasper is a Green Jasper, with inclusions of yellow, orange, and red, but is not the same stone, because the colours in Fancy Jasper are merely inclusions of the same stone. Bloodstone specifically contains inclusions of red iron oxide, not just other colours of Jasper.
The two types of Bloodstone that are the most widely accepted, as previously stated, are Plasma and Heliotrope. Heliotrope is a Greek name, it refers to the words “Helios” for sun, and “tropos” for turn. The name is a reference for the way the stone reflected the sun. The Plasma Bloodstone is a very deep green and opaque, with only a few specks of red iron oxide, lightly scattered throughout the stone. Heliotrope is a lighter shade of green and may contained deep green, and lighter green, as well as possibly a few specks of Yellow Jasper along with the red inclusions of iron oxide. The main source for bloodstone is in India, however is mined in the United States, as well as Scotland, and other less than significant quantities have been found throughout Europe. Several bloodstone seals, carvings, and busts have been found scattered all over the globe. Bloodstone is the birthstone for those born in the month of March, as well as being connected to those born under the sign of Aries.
