I got a pile of this from the playhouse collection. It's taken awhile to identify which of the picture jaspers accurately describes it, but until something closer surfaces, I think it looks most like McDermitt picture jasper.

Yet another species of stone from the Owyhee mountains in the Idaho/Oregon border area. This stuff has a lot of pattern. At first I was a little bummed when I cut it as it seemed soft and might not polish well. I had hoped for porcelain grade material like Morrisonite and Willow creek jaspers. I was elated when I put my first cab to the cerium wheel. It shined right up and looks great. I've got a bunch to cut still and it will be like Christmas morning with every cut anticipating the patterns inside.

Here's more general information about jasper.
