Why this rock is probably not a meteorite:
1) No fusion crust,
no smooth surface.
2) It's much denser than any common rock, and strongly magnetic, but
there are no metal grains visible (lower photo, sawn face).
3) The interior is dark and very fine grained; no mineral grains are
visible, just a few inclusions.

What is it?
This is a very nice piece of magnetite, an iron ore. Magnetite
is dark gray and makes a gray streak;
hematite is usually reddish and makes a reddish streak.
The reddish areas in this rock are probably hematite. Magnetite
and hematite are rare in meteorites and only occur in minor amounts
when the do occur.
