Boucheron, Noctua the owl ring in white gold and blackened 750 gold, the plumage entirely set with round-cut sapphires and amethysts, the eyes with amethyst cabochons surrounded by diamonds, signed, numbered E70605, finger 54-14, 20g Setting: Very good overall condition. Gems: Very good overall condition. The Boucheron bestiary The history of the Boucheron bestiary began in its workshops in 1866. From snakes and hedgehogs to chameleons, owls and frogs, the bestiary has gone from strength to strength. Clinging to an ear, encircling a wrist or neck, perched on a finger as if ready to take flight or jump, they all seem to be caught in their own movement. The jewellery work renders the animal surprisingly of realism.
