Laurence Graff Net Worth

Laurence Graff has an estimated net worth of $4.5 billion, according to Forbes Real-Time Billionaires, Laurence Graff profile (figures as of October 20, 2026). That is down from a peak of $5.5 billion.

Laurence Graff is a British jeweller and businessman best known for founding Graff Diamonds in 1960. He left school at 14 and learned the trade as an apprentice in London’s Hatton Garden. After an early shop partnership ended, he started selling his own designs to jewellers across England. By 1962, he had jewellery shops, including his first in Hatton Garden. From there, he kept expanding his name in the diamond business.

His career became closely linked to high-end diamond jewellery as Graff moved into the top tier of the market. In 1966, a jewel designed for the De Beers Diamond International Awards won the competition. By 1974, he was focusing on newly rich buyers from the Middle East, which helped broaden the business. Forbes says his wealth comes from diamond jewelry, and the company now has more than 60 retail stores worldwide.

How Laurence Graff makes money

Graff’s fortune comes mainly from Graff Diamonds International, where he is chairman. The company sells diamond jewellery at the luxury end of the market and runs more than 60 stores around the world. Forbes says he built the business from nothing after starting as a jeweler’s apprentice in Hatton Garden. Over time, he turned hands-on trade skills and independent jewellery sales into a global retail company that serves wealthy buyers and famous clients.

His wealth also includes other private assets tied to diamonds and property. Forbes notes that he owns a polished diamond trading firm in Switzerland, real estate in London’s Mayfair district, and a stake in a South African diamond wholesaler. He also owns Delaire Graff Estate in Stellenbosch, with a vineyard, winery, boutique hotel, and restaurant. Together, those holdings show that his money comes from both luxury jewellery sales and valuable business and property interests.

Forbes net worth over time

Forbes estimated Laurence Graff’s net worth at $5.5 billion on the 2019 World's Billionaires List. In the following years, that estimate moved down to $3.4 billion on the 2022 list, and it stayed at $3.4 billion on the 2023 and 2024 lists. Even with that drop, the core of his wealth stayed the same: diamond jewelry, a trading business, property in Mayfair, and a stake in a South African wholesaler.

The estimate later moved back up. Forbes put him at $4.5 billion on the 2025 World's Billionaires List, and the same figure appeared on the 2026 list. As of October 20, 2026, Forbes' real-time billionaires tracker also showed $4.5 billion. Forbes describes a business that still operates at the top of the diamond jewelry market, supported by store sales, trading interests, and real estate holdings.
