Found near Gold Canyon, AZ. Looks like something is growing in stone.

Very cool specimen .. Sorry no idea on what type of mineral/crystal it is though. Was thinking calcite though.

Thank you. Identification for myself gets very confusing, even with books.

Agatized fossil, maybe coral, kind of reminds me a little bit like coral fossils I've found near payson Az, just a guess though.
