An impeccable Georgian ring on which Cupid plays the diabolos, a yoyo/game thingy that kids in the Napoleonic era messed with. It says "Je me fait un jeu dagiter les coeurs", which means “I make shaking up hearts a game”. Look closely - the yoyo part looks like two hearts, right? 
The trio of colors in this agate specimen is astounding. Perfect condition: not a scratch on it!
