From Limpopo Province, South Africa. The green is epidote, the red piemontite—two minerals combined. The pairing suggested ""dragon's blood and scales,"" and the name followed.

Ancient legend held that a fallen dragon's body turned to stone. Green for scales, red for blood. Warriors carried it into battle as a talisman to return without shedding a drop.

Mineralogically, it is not jasper at all, but a composite of epidote and piemontite. The common name took hold long before the classification caught up. Imagination moved faster than taxonomy.
