Hawk's Eye is a variety of shimmering quartz whose fascinating profound blue green playing with light is due to non-oxidized crocidolite fibers. This gem is cut in cabochon or sometimes very slightly faceted to highlight its golden sheen. It's in South Africa that you'll find the biggest deposits. But like Tiger's eye and Ox's eye, Hawk's eye can be found in India as well, or Myanmar, West-Australia and a little bit in the U.S. Its unique look makes it a prized stone in Jewelry, while still having a decent price.
