This rock or object was found 60+ years ago in a field in Tennesee. It has a black outer coating and what looks like a silvery flakey inside that seems to radiate from the center of the object. There is a small round speck in the middle that looks like a small piece of rust. When I received this object we measured it and it was surprizingly very round and only differed by a few hundreds of an inch on all sides. It had a crack in it and I was told that the gentleman that found it tried to break it open by prying in the crack. So I assumed this object was very hard because it was still in one piece. Wrong ! After showing this to some friends at work we noticed it was begining to crack more, so I decided to break it open. Wow we have no clue what this is. Its like fibers all facing to the center of it. Oh yeah we also tested it under a very powerful metal detector and it did not detect it. Also under a very powerful magnet hanging from thread it did not desturb it at all.
