Fire Agate

Fire agate forms in thin brown layerss that refract the incoming light, giving the gem its "fire". The refraction often creates pattern remiminiscent of a dragon's scales, which makes it prized by sorcerers who claim to trais their lineage back to dragonkin. A well-cut stone has its outer layer polished and ground away until only the fire is visible.
