Hello Phil, All, I'm pretty sure Jeff is right on this one - I found a similar inclusion in a piece of Tamdakht recently, and upon inspection with a microscope, it became apparent that the bright blue inclusion I'd seen was merely an opaque and iridescent film on the surface of a troilite inclusion. As has been noted, a similar phenomenon occurs with "peacock ore," and on many other metallic minerals as well. It's some sort of a byproduct of oxidation on the surface of the inclusion. Regards, Jason
