    Similar in appearance to Hawk's eye, or Tiger's eye. Chatoyancy, appearing in these varieties of quartz, is caused by fibrous inclusions. They are generally cut en cabochon, but is often cut into round pieces for necklaces and pendants. A golden yellow reflection on a brown stone is called tiger's-eye. If the stone is blue-grey or bluish, it's colored by crocidolite, and is known as hawk's-eye. A darker brown, or mahogany-colored stone is known as bull's-eye or ox-eye.
