Heliotrope is another term for bloodstone, a form of Chalcedony, which is cryptocrystalline quartz. Heliotrope is green jasper with red inclusions. The red is sometimes caused by iron oxide or red jasper. The 'classic' Bloodstone is green jasper rock with spots of red throughout the stone. Sometimes yellow and/or other colors of jasper will be within the rock. Having some other colors with the Bloodstone is possible, but these multi-colored gemstones are usually called 'fancy jasper'.
Bloodstone is the original birthstone for March. Today, Bloodstone and Aquamarine are both considered the gemstones for March.
