These two characters are from the Devil card in the Rider-Waite Tarot deck. The Devil is card number15, signifying extraordinary efforts, fatality and that which is predestined. These are the faces of the man and woman who stand chained by the devil's side. These are actual tarot cards cut to fit 20mm glass cabochons.  These are NOT waterproof, so don't wear it in the shower or clean it with a liquid solution. A cleaning cloth works perfectly.
