A worn, rounded nugget of fibrous Sillimanite makes up this hand specimen. It shows no discernable crystal form and is rounded and smooth, with a dull pearly luster. The material has colors ranging from creamy-white to dark brown with a hint of violet, and is completely opaque. A few areas show a faint schiller. There is no host material present.
