What is Coprolite?? It is Fossilized Dinosaur Poop! And it is pretty!! We are offering this in our new size Pudgykins, which is bigger than a Minikins and smaller than a Size A bead. These beads have a solid sterling core with an inside diameter of 4.37mm. Our Coprolite comes from "The Four Corners", the only place in the US where four states borders touch. This is a stone of transition and growth.
