Lovely lot of Cornflower Blue to an almost Electric Indigo Blue Kyanite most likely from Tanzania (This was sold to us as being of local origin but that is HIGHLY unlikely). This is some of the nicest material that we have seen for Kyanite in color. Overall the material is running roughly 20%+ Facet Grade; however, most stones tend to be thin and weight loss with faceting will be high as is typical with Kyanite. Most of these are NOT large pieces and the better material is at the smaller end. Overall this would probably be classified as commercial faceting material. Our estimate on Facet Grade material in the lot is conservative as much of the material is too thin to facet and therefore was left out of the Facet Grade percentage. This material was sold to us as being locally produced but that is EXTREMELY unlikely considering we found some other stones in the parcel that were removed but looked like typical Tanzanian Rough.

Most stones are fairly slender elongated crystal sections and the material is pretty uniform in size and shape. Some of the stones do have some very distinct color banding as is common in Kyanite while much of it is a solid color with little or no color banding.

1. Kyanite is a Sky-blue to Colorless mineral that occurs in thin-bladed crystals and crystalline aggregates. The material can occur in a variety of colors; however, most material tends to be a bluish shade and/or a greenish blue shade. Cleavage seems very distinct with some material looking kind of like mica. This looks like it is another one of those Kunzite kind of stones to cut so we don't advise this for the amateur.
