Might be! Best way to check is test for nickel. Iron/nickel combo so extremely rare on earth, it is the best way to test for METEORITE! Let us know. TTC

Maybe.
First need some tests. Most require grinding a "window" into the rock. Use a carbon-steel file to grind a small flat space showing the interior of the rock. Doesn't need to be large, a few mm's across should be OK. Need to post a close-up of the window created.
Something is odd about your rock. Doesn't look black on my screen, looks almost bluish.

Just realized if the rock came out of a great lake, you may not be the owner. Similarly, if a meteorite falls on a navigable body of water, it belongs to the feds. May want to revise your original post.

Hello oiztoy,
Here's an interesting link:
Check out the section on the ohm meter and chemical tests.

Probably not a meteorite, more likely an iron-rich schist. Cut a slice from it with a rocksaw or have it cut at a shop that cuts granite, then sand & polish a cut side, (never use a file, metal from a file will contaminate the specimen), use aluminum oxide sandpaper, start with 60-grit and work yer way up to 1200-grit, use the 600-1200 grit papers DRY even though their concidered wetsand. Then you'll have a specimen worthy of presentation to a formaly educated geologist who would be capable of identifying it from just a visual inspection.
