More information

Falcon eye is a mineral and a variety of quartz. It consists of quartz grown with fibers of crocidolite (blue asbestos). Falcon eye is dark blue with a characteristic chattoyance effect when the stone is polished. The blue falcon eye will transform into the golden tiger eye by oxidation for many thousands of years. The largest site is Griquatown in South Africa. It is also found in Wittenoom Gorge in Western Australia.

Tiger eye is a quartz variety. The color of the stone is yellowish brown to brown, streaked and opaque. Repositories include Africa, India, Mexico, California and Australia. Tiger Eye is caused by silicification of black blue crocidolite asbestos fibers that are called. This produces solid inclusion of hair-like crystals in the quartz. By the oxidation of the original crocidolite fibers rise to the gold shiny limonite fibers of the stone. Tiger Eye is so called because the stone has a light reflection reminiscent of the eye of a tiger. This slit-shaped light hot chatoyeren or kattenoogeffect. When the stone cabochon (BOL) is cut, the beautiful kattenoogeffect is most visible. The color of the stone gives it its name: the red species called Catseye, the Hawkeye blue and yellow Tigereye (golden yellow, golden brown).
