A new piece from the Quatre contes de Grimm High Jewelry collection presented in July 2018, the Pomme de pin clip is from the tale The Town Musicians of Bremen and evokes the pine tree that provided the animals with nocturnal refuge. It depicts three pinecones in "Navette" Mystery Set™, poised on a diamond branch budding with young shoots. Two of them are set with emeralds of limpid and luminous green, while the third is made up of diamonds. Creating the "Navette" Mystery Set with emeralds was a genuine challenge.
To reproduce the curve of the pinecones, the buff-topped stones had to be intricately cut and polished into a slight dome, individually and by hand. The task was made more difficult by the fact that emeralds are the most delicate precious stones. As for the marquise-cut diamonds that adorn the third pine cone, the difficulty involved setting them in such a way that the underlying metal would not alter the transparency and limpidity of the stones.
