The consensus seems to be ringwoodite. Marc Fries has generously volunteered to personally examine the meteorite. I'll let the list know what the final analysis is. Hopefully, it won't be something embarrassing, like a piece of my daughter's crayon :].

It's quite pretty, actually, and has been noted in several meteorites. It would take some 'splaining to put it in the middle of a troilite grain, but what the hell, eh?
