Blue Kyanite

This natural kyanite, of Nepalese origin, is distinguished by its deep blue color with areas of uneven color. Oval in shape with dimensions ranging from 3.90x2.90 mm to 4.10x3.20 mm, and weighing 0.20 carats, this kyanite has inclusions visible to the naked eye, which adds a touch of authenticity and character to each stone. It is important to note that the kyanite in this lot has not undergone any treatment, thus retaining all its natural properties. There are also differences in color shades between the stones in this lot.

The chemical composition of kyanite is Al2SiO5, an aluminum silicate. It belongs to the group of aluminosilicate minerals, which also includes andalusite and sillimanite, all of which have the same chemical composition but different crystal structures. Kyanite forms under conditions of high pressure and temperature and is often found in metamorphic rocks.

This naturally occurring kyanite is an excellent choice for collectors and jewelers looking for genuine, unaltered gemstones.
