|Sugilite is a relatively rare cyclosilicate mineral with the complex chemical formula KNa2(Fe,Mn,Al)2Li3Si12O30.|
Sugilite was discovered in 1944 and is found in Japan, Canada and 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 named for the Japanese geologist who discovered the first specimens.
