Graff

London jeweller, known for large, rare diamonds and its own cutting.

Laurence Graff began as an apprentice to a London jeweller and set up on his own in the early 1960s. The firm grew by buying and cutting large rough stones and has owned some of the world's most famous diamonds.

Graff controls the whole chain from rough stone to jewel and has workshops in London. The firm has shops in major cities around the world.
