About sillimanite Gemstone
Sillimanite (also known as Fibrolite) is a polymorph with Andalusite and Kyanite. A polymorph is a mineral that shares the same chemistry with another, or other, minerals but has a different crystal structure. Sillimanite is the rarest of the three trimorphs. Sillimanite is mostly known as a cats eye gem when in its fibrous, massive form, but beautiful, clean faceted gems are also available although faceted gems are rare because clean Sillimanite is scarce and difficult to cut.
Sillimanite is found in many locations worldwide but gem quality crystals are quite rare. The only sources of gem quality Sillimanite crystals are Orissa, India; Mogok, Myanmar (Burma); Ratnapura, Sabaragamuwa Province, Sri Lanka
