Kyanite

I know that the kyanite metamorphic minerals collectors are after are blue, but these are very shiny deep navy-black. The turquoise - bright blue colors are from the scanner where the light is reflected from translucent crystals. Anyway, I did collect this sample, gods knows from somewhere. Most likely central Texas. Each crystal about a cm or a bit more in length.
