It looks like obsidian. If it is a meteorite, it would very likely be magnetic, obsidian is not... It would seem very heavy for its size. Again, some meteorites in the cross sections show striations because the component elements will not mix together. I was able to see a bunch of meteorites at the Michigan Technological University Mineral Museum this summer. Worth the trip.

You can have it tested. There are several sites which will return your rock after testing. You may lose ten to twenty percent of its mass. If it were a meteorite it would be very valuable. Meteorites vary in value. Known impacts with witnesses are most valuable, rare types and composition are also extremely valuable For what it's worth, i still think it is obsidian..
