I find some sea shell fossils in our drive way gravel. Most of it around here is locally quarried so back to the ancient 'Missouri used to be a sea' theory. We can buy what they call Rip Rap which is large pieces of rock. When we had a load hauled in to stabilize the soil on the north side of our house which is on a slope, I spent months combing through it. There were some interesting crystal formations in it along with orange fossils about as big around as a soda straw and up to an inch long. I finally decided that it has to be fossilized coral. I've got it saved in a small jar somewhere. I'll hunt it up and take a picture.
Where do you all get your stones for tumbling? Beside on your own property that is.
My husband bought my Madagascar stones on Amazon. Lot of them cracked and broke while tumbling. Since this is my first foray into tumbling I had no idea if this was pretty standard or if he just got stuck with substandard rocks.
I'd like to get my hands on some obsidian to tumble and maybe Apache Tears but want to find a good source for rough stones.
