Known for its diamonds and its unmistakeable mint-coloured boxes, Tiffany remains one of the most iconic jewellers in the world. The boutique offers exquisite baubles, gifts and engagement rings, as appealing to ladies who lunch as to those in the corporate sphere. In addition to the glitzier items in Tiffany’s catalogue, seek out the wearable silver necklaces for an instantly chic update. The collections designed by Jean Schlumberger and Paloma Picasso are particularly covetable.
