Comments:
Kyanite from Nepal is hands down the best kyanite in the world. There's some stiff competition from Africa, and Brazil, and maybe a few other places, but the stuff from Nepal is just consistently mind blowing.
The two smaller ones (about 7.25 ct. each) - are suited for tablet shaped gems -- either large multi-color cabs, or rose cuts, or double-table faceted gems.
The large one has the depth for an outstanding faceted gem. There is one very shallow crystal delamination at about 1/2 mm depth, and a few edge dislocations that are all away from the center of the stone. Mostly in just one corner. It's about 85%+ clean (VVS+), so with just a little pre-forming, you'll be ready to cut the bluest gem you've ever seen!
