I found these on a beach in northern canada. The one is yellow/orange with a slightly raised beige in color coral design, smooth in texture.
This other one is pink crystal like with gold/silver looking flakes. Rock was found in chunks. Some of the flakes were found laying by the rocks. These flakes do not stick to a magnet. They are a little more silver than gold color. Outside of this rock is beige, black, those flakes. It looks like all these small stones got joined together on the outside. These flakes are all over inside it and a little on the outside. If these rock chunks were put back together it might be around a foot or more. Hard to tell.
