KYANITE SPECIMENS
PARCEL AS PER IMAGE
LARGETS PIECE 48 x 19 x 10 MM
SOURCE FROM BRAZIL
Kyanite is a polymorph with two other minerals; andalusite and sillimanite. A polymorph is a mineral that shares the same chemistry but a different crystal structure with another, or other, minerals. 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. The hardness of kyanite is approximately 4.5 when scratched parallel to the long axis of the crystal and approximately 6.5 when scratched perpendicular to or across the long axis. Other minerals usually have variable hardness on different crystal faces due to a different concentration and oreintation of the atoms in the structure

Quick shipping with FedEx to the US. It was well packaged. The one I received did have a small crack and chip in the lip, but stuff like that is expected with a natural material like this. I'm happy with my purchase.
