The impossible has been done!

Dutch Diamond Technologies is the first company in the world to have developed the unique processing technology to make a perfectly round diamond. Diamond spheres are heat, wear and chemical resistant. Diamond, whether natural or synthetic, offers an extraordinary combination of optical, thermal and mechanical properties that, when combined, make it a material that has potential in many advanced optical applications. We are also able to mount the spheres on a shaft.


  • Exceptional wear-resistance
  • Very low coefficient of friction
  • Chemically inert
  • Non-magnetic
  • Operating temperature up to 400 °C

Solid diamond spheres

The sizes of full mono crystalline diamond spheres range up to a diameter of 3 mm. Calibration is traceable to the National Institute of Standards and Technology (NIST).

Advantages of solid diamond spheres:

  • No built-up of material when scanning aluminum
  • More robust with point loading
  • High wear resistance on ceramic
  • G10 Roundness (<250nm)
  • For universal use

Coated diamond spheres

The size of our polycrystalline spheres range from 1 to 8 millimetre. These high precision spheres will be available from 0.5 up to 12mm in the near future. For wear and non-friction these spheres almost have the same advantages compared to the monocrystalline spheres.

Advantages of diamond-coated spheres:

  • No build-up of material when scanning aluminium
  • G5 roundness (<130nm)
  • Various larger diameters possible
  • Less expensive
