  • Sugilite (also known as luvulite) is a relatively rare pink to purple cyclosilicate mineral with the complex chemical formula: KNa2(Fe,Mn,Al)2Li3Si12O30. Sugilite crystallizes in the hexagonal system with prismatic crystals. The crystals are rarely found and the form is usually massive.

    Sugilite was first described in 1944 by the Japanese petrologist Ken-ichi Sugi (1901-1948) for an occurrence on Iwagi Islet, Japan where it is found in an aegirine syenite intrusive stock. It is found in a similar environment at Mont Saint-Hilaire, Quebec, Canada.
