|Sugilite is a relatively rare cyclosilicate mineral with the chemical formula KNa2(Fe,Mn,Al)2Li3Si12O30.|
Sugilite was first described in 1944 by Ken-ichi Sugi for an occurrence on Iwagi Islet, Japan. It is found in a similar environment at Mont Saint-Hilaire, Quebec. In the Wessels mine in northern Cape Province of South Africa, sugilite is mined from a manganese deposit. It is also reported from Italy, New South Wales, Australia, and Madhya Pradesh, India.
|The most important occurrence was found in 1975 in the Kalahari Desert, northern South Africa. In 1979 a large deposit of gem grade sugilite was found 3200 feet below the original discovery.|
Sugilite is also known under the trade names of "Royal Lavulite" and "Royal Azel"
Sugilite crystallizes in the hexagonal system with prismatic crystals. It often contains black matrix with reddish brown or yellowish blotches and ranges between 6 - 7.5 on the Mohs scale of hardness. Bright purple stones with little matrixing or blotches are the most valued. Gem grade sugilite is translucent and often brings high prices.
|In some circles sugilite is called “The Healer’s Stone”|
