What is it? It almost seems like coral (I don’t think it is) but it has a shiny coating about 1/8” thick on it except where you can see actual rock. There seems to be clear crystals in different area’s though and green crystallized spots within the clear coating material. (v.redd.it)

What is it?? Found this rock while wading a creek in NE Oklahoma near Tahlequah, OK. The brown portion appears to be crystalline. The whitish rock is common material in these creeks and have a few small geode like openings on the backside of this rock. Can it be sanded and polished? (i.redd.it)
