FUN FACTS: Pietersite is known as the "Tempest Stone" because it looks like an ocean during a storm. It's the cross between Tiger's Eye and Hawk's Eye (blue), and is in a less formed state (hence its less-uniform appearance).
Tiger's Eye is actually quartz-replaced asbestos. So, the pretty fibers that create the stone's signature chatoyancy effect are no longer dangerous (unlike a real tiger!).
