Boucheron has a thing about snakes. The latest collection from this maison, called 'Cabinet de Curiosités', is full of weird and wonderful creatures of the night, and lots of slithering serpents. Wrapped around your finger, bejewelled scales shimmering with colour, a serpent's head guards a luscious precious stone. Pythons with verdant tsavorites and diamond markings meander up the arm. The little forked tongue can be retracted for more formal occassions.
