Sillimanite is named after the American gemologist Benjamin Silliman. Sillimanite is often cut as a cabochon shape as this stone is very rarely transparent. Stones that have channel or feather-like rutile inclusions can sometimes create a cat's eye effect. This makes the stone a more attractive and valuable. Sillimanite is found around the world, but the largest deposits are found in Tanzania, Burma, Sri Lanka, India and Brazil. Sillimanite has a hardness of 6-7, which makes it an excellent stone for jewelry.
