Blood Stone

Bloodstone

Bloodstone is also known as heliotrope. It is a dark green variety of chalcedony colored by traces of iron silicates and with patches of bright red jasper distributed throughout its mass. Particles of chlorite or included hornblende needles cause the green color. Red spots are caused by iron oxide.

The name heliotrope derives from the Greek word helio, meaning “sun,” and trepein, meaning “turning.” It has in the past and is in the present time considered a great curative. In some parts of the world it is still believed to stop every type of bleeding, clear bloodshot eyes, act as an antidote for snakebites, and heal urinary troubles.

As with other chalcedonies, bloodstone occurs through deposition from low-temperature, silica-rich waters percolating through cracks and fissures in other rocks. The most important deposits of bloodstone are in India, also in Australia, Brazil, China, and the United States.

In the trade the word blood jasper is sometimes used to describe bloodstone. However, bloodstone is not a jasper. Bloodstone has also been called hematite, probably because the German word Blutstein refers to hematite.

Bloodstone is the birthstone for the month of March.
