Hawk’s Eye is the name given to blue or blue-gray Tiger Eye and, like golden Tiger Eye, it is a silicified asbestiform crocidolite (crocidolite with strands of asbestos running through it, which over time have been replaced with Quartz. The fine layers of Quartz crystals within Hawk’s Eye reflect light and give the stone its characteristic silky sheen. The most important source of stone is South Africa, but it is also found in India, Myanmar, Sri Lanka, Western Australia, Brazil and California. Hawk’s Eye is also known as Blue Tiger Eye, Falcon’s Eye, Rodusite and Silicified Crocidolite.
