Tiger's Eye

Tiger's Eye is a popular, durable quartz variety featuring a distinct "cat's eye" shimmer, typically in golden-brown, blue, or red shades. As members of the quartz group, tiger's eye and the related blue-colored mineral hawk's eye gain their silky, lustrous appearance from the parallel intergrowth of quartz crystals and altered amphibole fibers that have mostly turned into limonite.  The chatoyancy manifests as a silky, wavy shimmer across the stone. Tiger's eye will take a great polish and make dramatic finished pieces.
