  • Sillimanite Gemstones

    Sillimanite is a type of aluminum silicate that is related to both andalusite and kyanite. In fact, these three minerals are polymorphs - they share the same chemical composition but have different crystal structures. Kyanite is formed in a lower temperature and higher

  • Kyanite

    Kyanite is a member of the aluminosilicate series, which also includes the polymorph andalusite and the polymorph sillimanite. Kyanite is strongly anisotopic, in that its hardness varies depending on its crystallographic direction.
