Why this rock is probably not a meteorite:

1) No fusion crust.  The rock is rounder than the previous one because it's been eroded by rubbing against other rocks in a body of water.  

2) If this were a lunar meteorite, as the finder suspected, the light-colored things would be clasts.  However, clasts in lunar meteorites would not have rinds, and nearly all of these have some kind of rind or reaction rim.
  
What is it?

This rock is an amygdaloidal basalt, like the previous one, in which the vesicles are now completely filled with a secondary mineral like calcite or quartz.
