| Pyrophyllite/ Sillimanite/ Kyanite |
Kyanite is a member of the sillimanite group of minerals. This mineralogical group includes kyanite, andalusite, and sillimanite – all of which are naturally occurring polymorphs of Al2O3.SiO2. These minerals are also commonly referred to as the 1:1 “alumino-silicates”.
Kyanite is an attractive mineral that has a near sapphire like blue color in some especially nice specimens. Kyanite has a unique characteristic in that it has a wide variation in hardness, in the same crystal.
