Blue HawkEye Tiger Iron Crystal Bracelet

Writing in 1873, Wibel concluded that tiger's eye forms when crocidolite (a blue form of asbestos) in a rock is replaced with fibrous crystals of chalcedony, a form of quartz. Blue Tiger Eye is formed when the mineral crocidolite, which is blue in color, is replaced by silica. This process gives the stone its unique color. Blue Tiger Eye is typically found in South Africa and is considered rare, making it sought after by collectors.
