Graff

Laurence Graff started as a fifteen-year-old apprentice in London's Hatton Garden and built the house that handles more important diamonds than anyone alive. Founded in 1960, Graff is the jeweler of record stones — the 603-carat Lesotho Promise, bought rough and cut into 26 flawless diamonds; the Wittelsbach-Graff, a historic blue he controversially re-cut to perfection; the Graff Pink, the Graff Lesedi La Rona at 302 carats, the largest square emerald-cut diamond in the world.

The house is vertically integrated to a degree unusual even on Bond Street — from rough sourcing through cutting and polishing to the salon — which is why record stones keep passing through its hands. The design language stays deliberately classical: the stone is the argument, the setting its frame.

The Paris salon on Rue Saint-Honoré brings that inventory to the Faubourg's gold triangle. Multi-carat solitaires as everyday stock, high-jewelry suites built around stones with their own names — this is the maison where diamonds have biographies.
