That's what I thought at first, It laid in the floorboards of my truck, for weeks. I cleaned it, it looked napped, first I took it to the local pawn shop, to see what he thought, he ask if I wanted to sell or pawn, I said Keep. Then showed this guy who was a gem vendor at a native festival, he was a member of a geologic society, and said it was a very large core, one of the clearest he has ever seen, he two made offer, I said, I'll keep it.. took to a medicine wheel ceremony, had it energized in a bowl at center of circle, on a full moon. Only since the energizing, did I started to see the holographic images, If you believe in that kind of stuff,Thanks Justintime..
