Tiger eye

Tiger's eye got its name in the second half of the 19th century because of its fibrous structure, which in the right cut produces a wavy glow of light reminiscent of animal eyes. Synonyms are cat's eye quartz, quartz cat's eye and schiller quartz. Tiger's eye is often confused with hawk's eye.

The mineral is found in South Africa and Northwest Australia.

Its colour is golden yellow to brown with iridescent areas.
