I was lucky enough to be given a piece of rainbow obsidian to cut up recently. I found it very interesting as the outside was a grey with a sharkskin like texture from the flow banding, but as it was slabbed some beautiful colorful banding started to appear. Hope i can manage to keep the colour in a couple of cabs.
