Sorry about the one that you think won't tumble. The big round one is very green when it's wet. I did grind a little on one side of it but didn't get far with my power drill and the little piece with the shell in it also has ton of tiny crinoid stems inside it. I have a piece of it that I ground down and polished that looks pretty cool.
Hey sorry I just saw this yesterday. I actually got the wet saw out yesterday and cut up one stone I had big eyes to do more but after the one my arms were gone or I should say my shoulders wait till you see this piece I cut up yesterday I'll do a short. I'm going to be getting the grinding pads set up out probably at the beginning of the week and work on a few projects to include that one stone and I'll send you some pictures of it after I do. I'd like you to send me a picture of that piece that you polished up with the crinoid system in it. I'm curious to see what it looks like I have a bunch of rock I know have fossils in it and they need to be uncovered but I've never done anything like that before I'm interested though. I got some muriatic acid and would like to use that on some of the stone that I got but I'm not sure how it works and what rock it dissolves. Well hope you're having a good day man
