The mineral aggregate heliotrope (from Greek ἥλιος, hḗlios “Sun”, τρέπειν, trépein “to turn”), also known as bloodstone, is a cryptocrystalline mixture of quartz that occurs mostly as jasper (opaque) or sometimes as chalcedony (translucent). The "classic" bloodstone is opaque green jasper with red inclusions of hematite. The red inclusions may resemble spots of blood, hence the name bloodstone. The name heliotrope derives from various ancient notions about the manner in which the mineral reflects light. These are described, e.g., by Pliny the Elder (Nat. Hist. 37.165).
