The combination of the ocean blue kyanite with black mica is so beautiful. The stick-like shape is great in the hand. The kyanite has beautiful sheen and the black mica that is interspersed has great sparkle.
Kyanite is a polymorph with two other minerals, andalusite and sillimanite. It's an aluminosilicate mineral, which gives it the blue color, and is found found in aluminium-rich metamorphic pegmatites and/or sedimentary rock. Kyanite in metamorphic rocks generally indicates pressures higher than four kilobars. It is commonly found in quartz.
