Spotted this specimen on Ebay listed as Microlite. Was wondering anyone else's opinion about it. I have never seen Microlite with this iridescence and so metallic looking.
I'm pretty sure that's magnetite, and it's also probably from Afghanistan. The matrix looks a lot like the stuff from Marki Khel, Nangarhar Prov. (clinochlore, possibly with a chrome diopside)
