Falcon Eye

Background * History

  • Hawk’s Eye or Falcon’s Eye is a blue-gray to blue-green opaque gemstone variety of fibrous Quartz. It belongs to the large family of Quartz crystals and is sometimes known as ‘the Falcon’s Eye’, or as ‘blue Tiger’s Eye’.  It is a variety of Macrocrystalline Quartz. Falcon’s Eye is actually a Pseudomorph of Quartz. A Pseudomorph is one mineral that changes into another mineral over time. In the case of Falcon’s Eye, it began its life as Crocidolite and was later transformed into Quartz. Crocidolite is a fibrous blue mineral belonging to the Riebeckite family of Amphibole Silicates. It is considered to be one of the several forms of Asbestos. The transformation of Falcon’s Eye begins as Quartz slowly becomes embedded between the fibers of Crocidolite, eventually completely replacing it while retaining the fibrous shape of the original mineral. Falcon’s Eye is famed for its chatoyancy, reminiscent of the ‘eye of a hawk’. It is closely related to Tiger’s Eye and Pietersite, both of which exhibit similar chatoyancy. Tiger’s Eye is actually formed from Falcon’s Eye. As blue Crocidolite is dissolved by Quartz, traces of Iron Oxide remain; less Iron tends to result in the blue color of Crocidolite and if more Iron is present, color tends to result in the brownish golden color of Tiger’s Eye. Pietersite is any brecciated aggregate made up mostly of Falcon’s Eye and Tiger’s Eye. Pietersite has a rather chaotic swirling pattern because during its formation, materials that make up its composition are broken apart, swirled and are then reformed and cemented together by Quartz.
