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
