Red tiger eye is closely related to the well known golden coloured tigers eye. During the formation of tigereye, the bluish-gray mineral crocidolite is replaced by quartz while its fibrous structure is preserved. These newly created fibres produce the shimmering eye-like nature, known as chattoyancy. The red colour of this stone is produced when tigereye has been subjected to heat, either naturally or artificially.
As a healing stone, in addition to the usual properties of gold tiger eye, red is thought to provide motivation and stimulation.
