Information @ a Glance

  • Diamond is the hardest natural material. The Mohs hardness scale, on which diamond is a  corundum (sapphire) is  adequately attest to this incredible hardness, as diamond is exponentially harder than corundum.
  • Synthetic industrial diamonds are produced the process of High Pressure High Temperature Synthesis (HPHT). In HPHT synthesis, graphite and a metallic catalyst are placed in a hydraulic press under high temperatures and pressures.
  • Man made diamond’ is also known as synthetic diamond and this ‘man made diamond’ or the ‘lab created diamond’ undergoes a chemical and physical process in the diamond mines. The main difference between ‘Man made diamond’ and the natural diamond is the composition of three dimensional carbon crystals.


  • The mixture of products contains relatively large grains of diamond. Electron microscopy reveals well-crystallized mini-diamonds with diameters reaching up to 0.5 mm. The diamond yield depends strongly on the exact reaction conditions. Under 500 °C, only graphite is produced. Under optimal conditions, a diamond yield of 6.6 % is obtained
  • The process o synthesis and sinterization of industrial diamonds is performed under high pressure and temperatures (HPHT) up to 8,0GPa and 1800ºC in high pressure apparatus (HPA) capable of sustaining these values for determined periods of time using special hydraulic clasps.


  • Diamonds that are not sold as fine gems have been used in various industrial applications for years - including machining tools and abrasives. At Pure Spin TM Golf, we have developed a breakthrough technology for integrating "industrial diamonds" in golf club design.
  • All VFT models work with the highly precise fast tool technology – an innovative single point turning process utilizing PCD or diamond tools. The fast-tool technology produces ready-to polish lenses for all organic materials – toric, spheric, free-form, convex or concave surfaces with highest surface quality and form accuracy.


  • World demand for diamond is strong. The annual US$0.7 billion market for industrial diamond is now almost exclusively supplied by synthetic production of about 1000 million carats; 1 carat (ct) = 0.2 grams. Gem quality synthetics remain inferior and expensive to produce, so the diamond jewelry trade is supplied by mining natural diamond, derived from kimberlites, lamproites, and placer deposits.
  • The import of rough diamonds is prohibited unless the goods are imported in a tamper resistant container from a country which is a participant in the Kimberley Process and the shipment is accompanied by a valid Kimberley Process Certificate (KPC).


  • Industrial use of CVD diamond has been economics; the coatings were simply too expensive compared with existing alternatives. Lowering the cost of CVD diamond coating will make the use of CVD diamond much more economically and finally allow engineers the opportunity to exploit the large array of outstanding diamond’s properties in a wide variety of industrial and scientific  applications.

  • The company plans to manufacture this material at its industrial diamond production facility in South Africa.  ScD has already proven its use in a broad range of applications such as a thermal management substrate for the higher powered silicon-based electronic devices such as processors used in network servers and industrial PCs.  The diamond composite is also extremely wear-resistant and the manufacturing technology lends itself to making complex three dimensional shapes.  The inert nature of silicon carbide and the biocompatibility of diamond may lend itself to medical implant applications.
