Rainbow Obsidian Disc

This one of a kind Rainbow Obsidian disc is totally showing off on this sunny Seattle day.  Approximately 4" x 3" this piece is still with vibrant rings of color.  One of the curious things about rainbow Obsidian is that without direct light it often just looks black. 

When you purchase this  piece, don't be surprised when you open the box to an apparently black stone.  Just show it a little direct light and watch the rings of rainbow color emerge.
