[meteorite-list] Interesting crystal in meteorite - what is it?

[Galactic Stone & Ironworks]

What really strikes me about this possible lodranite is how closely it
resembles a H6 or H7 chondrite.  I've had a couple of UNWA stones that
look alot like this lodranite, but I never paid them much mind because
they didn't obviously look interesting - like some achondrites do or a
type loaded with chondrules.  I wonder if I've accidentally let
something like this slip by....

Best regards,

MikeG
