Element Six (E6) designs, develops and produces synthetic diamond and tungsten carbide solutions.

Since 1946, E6’s focus has been on engineering and optimising the diamond synthesis process to unlock innovative, diamond-enabled applications, including ultra-precision machining, drilling, thermal management, optics, wastewater management and quantum-enabled sensing.

E6 pioneered the development of single crystal diamond using the Chemical Vapour Deposition (CVD) method in the early 2000s.

With production facilities in the UK and California, the company has been at the forefront of a range of new developments in CVD diamond synthesis and industrial applications. Its patented technologies also drive a new production facility in Oregon, to supply gem-quality stones to Lightbox Jewelry.
