In the last photo, along the bottom edge it appears the dark blue is a thin coating over lighter crystals. I thought I read somewhere this was the case with Afghanite but I'm unsure. I've purchased this but it hasn't shipped yet. Your assistance is appreciated. I'm very much in the "buy what looks nice" stage of collecting.
This does not look like a 'fake' to me as far as something dyed, etc... but I don't feel that this is Afghanite. Looks like Gonnardite partly replacing Hauyne. Very typical material from the Koksha Valley.
