I would not sweat it. I do not believe that it is the stone you are thinking it is. Regardless of the colors, ie.. red/black , that stone sat there for a while and ended with only "1" bid. I am sure the lister was contacted and asked about the dark side which should have had a "Circle" stamp design with the word "Norton" in it. As you see , the lister failed to show the dark side of the stone. Maybe he was hoping for a "Big Fish" to swim by and leave a high bid.
