The mineral heliotrope, also known as bloodstone, is a form of chalcedony (which is a cryptocrystalline mixture of quartz and its monoclinic polymorph moganite). The “classic” bloodstone is green chalcedony with red inclusions of iron oxide or red jasper. Sometimes the inclusions are yellow, in which case the mineral is given the name plasma
The red inclusions are supposed to resemble spots of blood; hence the name “bloodstone”. The name “heliotrope” (from Greek – helios, Sun, trepein, to turn) derives from various ancient notions about the manner in which the mineral reflects light.
Heliotrope is the traditional birthstone for March.
The bloodstone is used for circulation of all energy in the body and helps to remove energy blocks. Bloodstone is used in the alignment of all the centers of the body. It also aids in the circulation of blood. It is good to have several pieces of Bloodstone in the home to increase the flow of life energy.
