2008 marks the 150th anniversary of the Parisian jeweler Boucheron and to celebrate it they have teamed up with Parisian Chocolatier La Maison du Chocolat to make this necklace. The necklace is coated and decorated with real chocolate which covers the chocolate gold skeleton. The centerpiece of the necklace is the 20.08 carat fancy brown tinted yellow diamond which is heart shaped and appears to be resting on the snakes tongue. La Maison du Chocolat have also created diamond shaped chocolates to commemorate the occasion.
