Hawk's Eye Hawk's eye is a blue-gray to blue-green fibrous variety of opaque quartz formed when quartz replaces the mineral crocidolite. Like tiger's eye, hawk's eye exhibits chatoyant stripes and a silky luster. When cut en cabochon, the surface of hawk's eye shows chatoyancy reminiscent of the eye of a cat. Pietersite, another popular blue-gray gemstone, is made up mainly of hawk's eye and tiger's eye. The most important sources for hawk's eye include South America, India, Namibia, Australia, Burma (Myanmar) and the United States.

man their gems are pretty good, and the prices aren't to bad either, I like checking out hte gems on there website, beceause the pictures of the gems are taken pretty well, and you can see the table, and the facets.
I love gemselect and I have bought a fair amount from them. The only complaint I have is not being able to save gems. I have a lot of projects so i am in the market for a lot of different gems and it's so disappointing to have to delete them all just to purchase one or two that I have saved in my cart.
