Rainbow Obsidian - Dragon Tooth
Rainbow Obsidian helps you to identify your own flaws and gives you a clear picture of the changes which are necessary to turn them into strengths. It can also be used psychically to enhance clairvoyance and is an excellent scrying stone.
Please note: flash was used to bring out the coloring of the stone. It looks like a black stone at first glance, but you will notice the band of pretty rainbow colors in the stone.
