Blue Kyanite Tongue - Silver Pendant

Blue Kyanite Tongue 

Color: blue, white, light gray, green, rarely yellow, orange, pink

Named in 1789 by Abraham Gottlieb Werner of the Greek word "kyanos," which means "blue," the common color of the species. The French spelling "Cyanite" has been commonly used by mineralogists throughout much of the 19th and early 20th centuries.

Kyanite is an aluminum silicate mineral and occurs in metamorphic high-pressure rocks, often in glass vines. Cyanite is characterized by its color (usually blue), different hardness, ideal cleavage and bladed crystal shape. Kyanite has an exciting two-tone blue and green banding in the semi-transparent glass blades.

The Greek term ' Kyanite ' derives from its name, which is also known in ancient literature as Kyanite. This can be found in metamorphic pegmatites rich in aluminum or in sedimentary rocks. The gemstone kyanite has linked names such as disthene and munkrudite. White-gray cyanitis is also called rheticitis.
