Kyanit, Werner. Kyanite, Jame- 

 son, Phillips. Anorthic: primary form a 

 doubly oblique prism, of which the ter- 

 minations are nearly rhombs. Occurs mas- 

 sive, disseminated and crystallized in long 

 and broad oblique four-sided prisms, which 

 are irregularly terminated, and truncated 

 on the lateral edges: they are either im- 

 bedded or intersect one another. Cleavage 

 effected Avith difficulty transversely to the 

 axis of the prism, but easily parallel to 

 the lateral planes. Colour generally pale 

 blue : also white {Rh(£tizite), grey, greenish 

 and black; in some crystals the blue and 

 grey are intermixed, and the blue is of a 

 deeper tint along the middle of the prisms. 

 Lustre pearly. Translucent; often trans- 

 parent. Streak white. Brittle. Fracture 

 foliated. Some crystals by friction become 

 negatively electric, others positively. H. 5 

 on the lateral planes : 7 at the extremities. 

 S.G. 3-54 to 0-61. Occurs chiefly in gneiss 

 and mica-slate.

Kyanite, when transparent and of a fine 

 blue colour, is sometimes cut and employed 

 as a gem. It is generally imported from 

 India cut and polished, as a vari-ety of
