Super heavy and slighty magnetic rock

Very heavy for it's size and is slighty magnetic. Might be just a rock but the weight is what has me wondering. Any ideas.

Kinda hard to tell. Most likely its iron stone or a mixture there of. Personally I'd probable smack it with a hammer to see the interior. Could also be a bit of dense granite. What made you want to pick it up?
