Green Kyanite Crystals

Green Kyanite has a Triclinic crystal system and is in the mineral class of silicates. It is usually formed as long, bladed crystals that can be up to a foot long. Kyanite’s coloring can range from bluish, green or aqua to almost colorless. Black sprays are also found in Brazil and are very brittle.

Quite often it is found with Andalusite and Sillimanite and it is an important refractory for porcelains, high temperature bricks and spark plugs. Until recently it used to only be found in the U.S., but it has now become available from mining efforts in Kenya and East Africa where they are uncovering some of the largest and clearest crystals to date.
