Plasma

This is dull, leek-green stone, often speckled with white (but not red) spots. Yellow markings are also sometimes seen. It is opaque to sub-translucent, and except for its markings, it is the same as bloodstone. The dark green color is due to inclusions of green earth (or delessite).
Prase is much the same as plasma, except that it is more translucent, and it may occur either as crystals or in crypto-crystalline forms. The name is derived from the Greek prason, meaning “a leek.” These stones are too uninteresting to be cut and used in jewelry, although they are occasionally seen.
The rough material is found in the eastern states of India, and in Germany.
