Bloodstone, also known as Heliotrope, is a form of Chalcedony. Its forest green color is caused by small crystals of Actinolite while the highly-sought red flecks are formed by the presence of Iron Oxides. The stone may also show yellow and white patches. Bloodstone is a healing crystal associated with courage, abundance and circulation. The stone helps purify the blood and balance the Heart Chakra.
