About Stone: Sillimanite was named after the American chemist and mineralogist, Professor Benjamin Silliman (1779-1824). Sometimes referred to as “Fibrolite”, the crystals occur in groups, resembling fibers. Sillimanite is a transparent to translucent mineral that ranges in color from white to gray to brownish to greenish. Sillimanite is formed from aluminum silicate and is mostly found as silky, fibrous masses and as transparent prismatic crystals with glassy luster. Best field indicators of Sillimanite are its crystal habit, color, brittleness and hardness if not fibrous. Sillimanite is one of three aluminosilicate polymorphs, the other two being andalusite and kyanite.
Metaphysical Properties: Sillimanite stimulates endorphin production, making it a “feel good” crystal. It helps you see that even the most menial or seemingly unimportant tasks hold an importance in your life. Sillimanite raises your energy vibration and brings loving thoughts of self-love. It supports the Spiritual Heart Chakra, Throat Chakra, and the intellectual body, allowing those three to work well together.
