Just to jump on the "me too" bandwagon, I have a clean pentagonal-shaped cavity in a small Gao I got from Al Lang 8 years ago. The cavity is at least 10mm across and as deep. I was hoping I could keep going through Al's stash to find the missing "crystal" but nada. The shape is distinctly "sided" as in a polyhedral crystal
Given a slight rounding of one side of the cavity this could have been a hexagonal shaped missing object. At the time I suspected either an olivine or iron crystal but discounted both as unlikely given this was a common chondrite. Given these reports now it might worth revisiting. Perhaps someone would help me make a mold of the hold to see what the crystal faces really looked like. I'll photograph it once it is unpacked. Perhaps large complete crystals do find their way into chondrites--however theoretically any large crystal would have grown long after the chondrite accreted. Else, there were some large crystals that survived the last solar system intact as the new solar system cranked up only to be cocooned within common chondrites. If the later scenario were true then these iron crystals should be as old or older than CAIs.
