Tiger iron is an altered rock composed chiefly of tiger's eye, red jasper, and black hematite. The undulating, contrasting bands of color and luster make for an attractive motif, and it is mainly used for jewelry-making and ornamentation. Tiger iron is a popular ornamental material used in a variety of applications, from beads to knife hilts.
Tiger iron is mined primarily in South Africa and Western Australia. Tiger's eye is composed chiefly of silicon dioxide (SiO2) and is colored mainly by iron oxide. The specific gravity ranges from 2.64 -2.71. It is formed by the alteration of crocidolite.

Famous quotes containing the words tiger and/or iron:
“The tiger in the tiger-pit
Is not more irritable than I.
The whipping tail is not more still
Than when I smell the enemy
Writhing in the essential blood
Or dangling from the friendly tree.”
—T.S. (Thomas Stearns)
