Tiger Eye is a durable quartz composite. It begins as
the fibrous blue mineral called crocidolite, which is comprised of iron & sodium. Most of us known crocidolite as asbestos. The transformation begins when quartz becomes imbedded between the fibers of crocidolite. This process will result in one of two gemstones. A blue
stone called Blue Tiger Eye or Hawk Eye or the golden brown stone called Tiger Eye.
