It is an exceptionally rare and very beautiful stone. Sillimanite is found in two forms. One is clear and crystal like, and the other is silky and fibrous. When it is found in its fibrous state, crystals occur in long slender prisms in parallel groups, resembling fibres, and this material is often called fibrolite.
Collectors love the stone’s lively lustre. Sillimanite can range in color from colorless to white, yellow, green, blue or brown. Crystals have a distinct pleochroism, showing pale yellowish green, dark green and blue from different angles. Some crystals demonstrate a cat’s eye effect. When polished as cabochons, they glow mysteriously like a cats eye at night. These crystals make beautiful rings. Sillimanite is a brittle stone, so it is a very difficult stone to cut, therefore only skilled lapidaries attempt to do so.
Throughout history, Sillimanite has been considered a rare gemstone that is known mainly to collectors. Deposits of Sillimanite have been found in Burma, Sri Lanka, Kenya and the USA. Recent finds in India have made Sillimanite more widely available, though it is still classified as a top collector's gem.
Due to the Collectors ongoing demand, I have made the SILLIMANITE the 16th piece in my
