At first glance, this might appear to be your typical polished Agate slice - but once you get this Agate into the light it morphs into something entirely different. Rainbows are produced when the light hits the stone, as it moves through the light the colors shift and change. Quite an unusual occurrence thats only found in a small percentage of Agates, and only a smaller percentage of those are preserved as complete slices. These slices are often cut into smaller pieces and sold as such. Plastic stand included.
