As a member of the quartz family, opaque through semi-translucent tiger eye has a hardness of 7 and has been a favorite carving and jewelry making material for centuries. Cameos, statuary, decorative tiles, building columns, ornamental carving of animals and urns have all been made of tiger eye, as well as cabochons and beads of many different shapes. Affordable and abundant, tiger eye is a very popular material with wire jewelry designers. Its natural, earthy shades of gold, yellows, and browns go with about any outfit and are a popular choice when making men's jewelry, especially rings.
A carved big cat and a cameo, both made of brown/gold tiger eye and One of the perfume bottles in my collection is a great example of tiger iron from Australia (but carved in China).
