Bloodstone

Bloodstone is a red and green variety of Jasper. Christian legends says that Bloodstone was formed when some of Christ's blood fell onto Jasper at the foot of the cross and stained it with red patches. Christians then prized this crystal for this reason, carving crucifixion scenes into Bloodstone. Bloodstone is also prized in India as an aphrodisiac, with fine specimens of the gem being ground into a powder for this purpose.
