Seriously, the first thought that came to mind about this bead was "Rorschach test". The little section in the middle reminded me of an ink blot. I'm not sure what that says about my personality, but I thought it was sort of interesting and strange.
This would be a fun bead to pair with other unusual and mysterious looking beads and baubles. I love a great piece of jewelry that becomes a conversation piece.
Have a good one!
