Tiger’s Eye Skull from China
Tiger's eye
Tiger's eye is a golden-brown to yellowish quartz-like rock known for its silky luster and distinctive light-reflection effect, also known as chatoyance. This effect results from the fibrous structure of the original mineral crocidolite, which has been replaced by quartz during the silicification process.
Tiger's eye is mainly found in South Africa, Australia, India and Namibia. It is formed by the conversion of amphibole minerals into silica, retaining the original fibre structure. Its chemical formula is SiOâ‚‚ and its hardness is 7 on the Mohs scale. Well-known variants are falcon eye (bluish) and bull's eye or cat's eye (reddish-brown), created by incomplete or heated conversion, respectively.
