Stak Nala?

I bought this a year ago from a Pakistani dealer in Seattle, any guesses as to which mine or region it came from? I remember reading about Stak Nala material with pink or peach caps and I think the dark base may be a clue too.....any takers? Sorry, I've only got the one picture.

Indeed, could be. Is the dark base black & opaque, or some very saturated brown or green ?

I apologize I complletely missed your response!! Yes, the base is truly black and not a darker shade of green or brown and appears opaque like it starts out schorl and then gets into a strage almost pinkish/colorless zone and then into the orange cap. I will try to snap a pic of the termination as well, that would probably have been good info to have. Thanks for your help Aymeric!
