[meteorite-list] unusual crystalline structure found in NWA --your thoughts please

[Galactic Stone & Ironworks]

Very odd.  Looks like some kind of deformed chondrule.  I've never
seen anything exactly like it either.

Jason does awesome work.  His cabbing and polishing work is top-notch.

Best regards,

MikeG
