Our Chatoyant Sillimanite Gemstones Are 100% Natural - Unheated & Untreated

There are three natural polymorphs of Al₂SiO₅: sillimanite, andalusite and kyanite. Each of these minerals has the same chemical composition but differing crystal structure! Be sure to see our natural kyanite gemstones (as well as our blue kyanite in matrix mineral specimens) and our natural andalusite gemstones.
