Graff
4.7 / 5Bahnhofstrasse 16 · established 1960
Graff's boutique is at Bahnhofstrasse 16, and the house exists for one thing above all, exceptional diamonds. Laurence Graff started the firm in London in 1960 and it has handled some of the largest rough ever found, including the Lesedi La Rona. The bridal rings lean on that sourcing, so if the centre stone is the whole point, this is a serious stop.
