Element Six is a synthetic diamond supermaterials company and a member of the De Beers Group of Companies.

We are a global leader in the development, production and design of synthetic diamond supermaterials and operate worldwide with our head office registered in Luxembourg. Our primary manufacturing facilities are in Germany, Sweden, China, Ireland, the UK, the US and in South Africa.

For more than 50 years our focus has remained on the processing and synthesis of synthetic diamond supermaterials such as cubic boron nitride, tungsten carbide and silicon cemented diamond. One of the most useful and remarkable materials, the synthetic diamond is well known for being one of the hardest materials in the world and has many extreme properties. The business takes its name from carbon - the sixth element of the periodic table, thus: Element Six.

Our mission is to deliver extraordinary performance for end users through innovative supermaterial solutions. We focus on close strategic development partnerships with customers to deliver customised, innovative high performance products. The company strives to provide excellent customer service and to enhance productivity on a continuous basis.

Element Six is made up of two businesses; Technologies, which is 100% owned by the De Beers Group; and Abrasives, which is ~60% owned by the De Beers Group, with Umicore, a major global materials group, owning the remaining ~40%.

The Abrasives business encompasses our oil and gas, advanced materials and hard materials divisions. Abrasives utilise high temperature (HPHT) synthesis and high pressure to manufacture synthetic and cubic boron nitride (CBN) as well as high temperature sintering to produce tungsten carbide products. These supermaterials are used in applications including polishing, shearing, cutting, drilling and grinding. Diverse industrial sectors use these products in their manufacturing processes such as the wood-working, construction, road maintenance, electronics, mining, oil and gas drilling, aerospace and automotive industries.

The Technologies business utilises the extreme properties of synthetic diamonds beyond hardness, through manufacturing very pure diamonds using chemical vapor deposition (CVD) techniques. These properties have created new potential applications in a broad range of industries such as water treatment, semi-conductors and sensors, power transmission and optics. The unique properties of synthetic diamonds have the potential to solve some of the greatest industrial challenges the world faces, leaving synthetic diamonds well placed to enter an exciting era of growth to come.
