<P><p><b>Sugilite</b> (also known as <b>luvulite</b>) is a relatively rare pink to purple cyclosilicate mineral with the complex chemical formula: KNa<sub>2</sub>(Fe,Mn,<span class="mw-redirect">Al</span>)<sub>2</sub>Li<sub>3</sub>Si<sub>12</sub>O<sub>30</sub>. Sugilite crystallizes in the <span class="mw-redirect">hexagonal</span> system with prismatic crystals. The crystals are rarely found and the form is usually massive. It has a <span class="mw-redirect">Mohs hardness</span> of 5.5 to 6.5 and a specific gravity of 2.75 - 2.80.</p>
<p>Sugilite was first described in 1944 by the Japanese <span class="mw-redirect">petrologist</span> Ken-ichi Sugi (1901-1948) for an occurrence on Iwagi Islet, Japan where it is found in an aegirine syenite <span class="mw-redirect">intrusive</span> stock. It is found in a similar environment at Mont Saint-Hilaire, Quebec, Canada. In the Wessels mine in northern Cape Province of South Africa sugilite is mined from a strata-bound manganese deposit. It is also reported from Liguria and Tuscany, Italy; New South Wales, Australia; and Madhya Pradesh, India.</p>
