KYANITE CRYSTALS WITH QUARTZ
Large specimen
Brazil
A large and lovely specimen with long, blue, kyanite crystals intergrown with white quartz.
Kyanite is not only a beautiful gemstone but is also a mineral with an interesting geological history. It forms only at extremely high pressures – such as those that exist deep beneath mountain ranges as a result of continental collisions. It has been brought to the surface by hundreds of millions of years of erosion.
This is heavy specimen, weighing 2.3 kilograms.
These specimens are known to shed the odd crystal if roughly treated or during transit.
