Laurence Graff OBE (born 13 June 1938) is an English jeweller. He is best known as the founder of Graff Diamonds, supplier of jewellery and jewels.
Graff was born in Stepney in 1938 into a Jewish family, the son of a Romanian mother, Rebecca Segal, and a Russian father, Harry Graff. His father made suits off the Commercial Road while his mother ran a tobacconist and newsagents. His brother Raymond was born in 1947.
Graff left school and became an apprentice when he was 15. He soon went into partnership with Schindler, a jeweller, repairing rings and creating small pieces of jewellery in a small shop. That shop went out of business and so Graff began selling his jewellery designs independently to jewellers all over England. By 1962, he had two jewellery shops, including his first in Hatton Garden – the centre of London’s jewellery trade since medieval times.
In 1960, he founded the Graff Diamonds company. In 1966 he commissioned the English jewellery-designer Robert Thomas to design a diamond jewel to enter into the De Beers Diamond International Awards competition. The ribbon bracelet created won the competition. By 1974, he had begun specialising in selling to newly rich buyers from the Middle East. In particular, he supplied many jewels for Hassanal Bolkiah, the 29th Sultan of Brunei, who became a lifelong client and friend. One day, Prince Turki bin Abdul Aziz walked into the shop and bought everything including a 14 carat diamond. Graff has expanded his company, with over 35 stores in US, Europe, Asia, Africa and the Middle East.
Graff was appointed Officer of the Order of the British Empire (OBE) in the 2013 Birthday Honours for services to the jewellery industry.
