[meteorite-list] Good on list topic! Explain this!

[Tom Knudson]

Hello List, here is something strange that I am hoping someone can explain!
  This unclassified NWA has Veins running through it, I would have guessed
shock, but now I am thinking weathering. One of these veins at the edge of
the meteorite has a grain of sand (actually a few, but only one big one)
inside the vein.

 I am baffled, it is part of the meteorite now!!!!

It is the clear spot on the top middle of the picture.
