A London house founded in 1960, Graff is a reference for the large diamond and for high jewellery. The house examines and buys your Graff pieces — rings, diamonds, signed lines, watches — by appointment in London at 100 Hatton Garden or in Paris at 22 rue Drouot.
In a Graff piece the quality of the diamonds is decisive; the house, a diamond merchant itself, reads them in front of you — weight, colour, clarity, cut — and makes a firm offer to buy. A few minutes from New Bond Street, the house receives in London at 100 Hatton Garden; in Paris, at 22 rue Drouot.

Founded in London in 1960 by Laurence Graff, the house follows the diamond from the rough to the shop: it buys it, cuts it and polishes it itself. These are the lines one recognises.
A butterfly set with diamonds, in classic, silhouette or pavé version: a house motif since the 1970s.
A halo of pavé diamonds around a centre stone — round, pear, oval, heart or emerald cut; the name comes from a diamond of 90.97 carats cut by the house in 2000.
Loops of pavé winding on themselves, in rose, white or yellow gold; half-set bangles made to be worn together.
A ribbon bow paved with diamonds, inspired by the bond between Laurence Graff and his granddaughter.
A trellis of pavé in free geometry; in high jewellery, with yellow diamonds or sapphires.
Faceted, angular gold, plain or paved, each piece cut from a single block of gold.

We look at these six points in front of you, then we make a firm offer.
Weight, colour, clarity, quality of the cut: for a Graff ring, this is the essential. We weigh it and read it in front of you.
The Graff logo laser-inscribed on many diamonds, the signature and the number on the jewel.
Platinum or 18-carat gold; pavé, halo, shoulders: the workmanship counts.
Yellow diamonds, sapphires, rubies, emeralds: quality and origin are read on the piece.
A worn claw, an incomplete pavé do not prevent a sale; we value the piece as it is.
They add value to the piece, without being essential.
