Why this rock is probably not a meteorite:

It is a meteorite.
  
What is it?

This is the sawn, polished face on an ordinary chondrite, the most common kind of meteorite (click on image for enlargement).  The gray parts are grains of iron-nickel metal.  The round, often reddish things are chondrules. A thin fusion crust is just visible along the edge.  The widest dimension is 2.3 cm.

The photo was taken under strong light.  Under normal conditions, the color is less red and more brown.
