Sugilite is a somewhat obscure mineral named for the Japanese geologist who discovered the first specimens in 1944, Ken-ichi Sugi. It is becoming very popular in the jewelry trade and is expensive. Sugilite colors range from a pale grayish lavender to a deep dark purple with the bright purple stones having little matrixing or blotches being the most valued. Sugilite is also known under the trade names of "Royal Lavulite" and "Royal Azel"
