The story

Founded by Ernest Oppenheimer in 1946.1

Sir Ernest Oppenheimer formed Industrial Distributors in 1946, the first entity to focus on the industrial uses of natural diamond.

In 1956 it was decided that De Beers should make a concerted effort to produce synthetic diamond and, in response, a research group, called the Adamant Research Laboratory, was established and housed as a subdivision of the laboratory. Two years later, after intensive research into high-pressure and temperature techniques, a team led by Jan Custers and Henry Dyer produced successful results.

Their success in the synthesis of diamonds was announced to the world in 1959 by Harry Oppenheimer. A full-scale plant to produce synthetic industrial diamonds commercially started operation in Springs, Gauteng, in 1961, followed by a second plant in Shannon, County Clare, in May 1963. These two developments gave birth to the De Beers Industrial Diamonds group.

By the 1960s, the company was offering a range of diamond grit products that was followed by nickel and coated diamond materials plus grinding products based on cubic boron nitride.

The company acquired a manor house in Sunninghill, Berkshire, called Charters in 1975 and used it as a research and technical support centre. Charters was sold in 2002 to a residential developer.

In 1992, breakthroughs in chemical vapour deposition technology opened the opportunity to synthesize diamond films and a new raft of application areas became possible.

The De Beers Industrial Diamond Division acquired the super-abrasive distribution business from company Ernst Winter in Germany in 1996, as well as Winter“s joint ventures in other countries.

A new diamond research laboratory was officially opened in Springs, Gauteng, by South African President Thabo Mbeki on 1 November 2001.
