Bloodstone is a variety of opaque chalcedony with a hardness of 6.5 to 7. It is dark green with red spots and blotches. It is also known as Heliotrope, from the Greek meaning ‘sun turner,’ although the derivation of this name is not known. In the Middle Ages, the red spots in Bloodstone were thought to be spots of Christ’s blood, and special magical powers were attributed to the stones.
Bloodstone is a great purifier, a healing tool for dispelling negative influences from the auric field and bringing one’s subtle energies into wholeness and balance. When this is done for the invisible self, the benefits for the physical self will follow. Bloodstone grounds one fully in the body and with that grounding comes the enhancement of one’s capacity to function with strength, determination and courage through the whole range of challenges inherent in earthly life. Just as Bloodstone increases vitality, it also assists one in facing the realities of physical mortality and death. It is a good talisman for those who are ill, even if curing the illness is not possible, because of its power to let one look unflinchingly at the truth, whatever it is, and to move forward in the most appropriate ways.
