Company Overview


Founded in 1946, Element Six has developed to become a global leader in synthetic diamond and supermaterials manufacturing. Find out all about our story below.


Element Six is a global leader in the design, development and production of synthetic diamond and tungsten carbide supermaterials. Part of the De Beers Group, we employ over 1,900 people. Our primary manufacturing sites are located in the UK, Ireland, Germany, South Africa, and the US.

Our history

Since 1946, our focus has been on developing the diamond synthesis process to enable innovative synthetic diamond and tungsten carbide solutions. As well as being the planet’s hardest material, diamond’s extreme and diverse properties give it high tensile strength, chemical inertness, broad optical transmission and very high thermal conductivity.

Our mission

We strive to deliver extreme performance through the development of cutting-edge synthetic diamond and tungsten carbide solutions.

Our Promise

Our customers are at the core of everything we do. Leveraging our extensive risk management processes, we are committed to working together to minimise supply chain impact arising from the rapidly evolving global geo-political dynamics. A trusted, western supplier of super-hard material solutions, for over seventy years Element Six has pioneered material innovation for products with demanding technological requirements. During this time, we have continued to develop and optimise our proprietary synthesis and sintering platforms, along with our extensive micronising, machining and value add processes, in our global sites across the US, UK, Ireland, Germany and South Africa. To find out more, read our supply chain statement
