Sillimanite is also known as Fibrolite, and can be found in shades of yellow-green, brown, blue and white. It is an unusual crystal that not many have heard of, and is named after geologist Benjamin Silliman. Most Sillimanite is opaque and can rarely display a Cats Eye effect, but it can also be found in transparent crystals, mainly from Myanmar.
