Diamond manufacture - innovation and precision
 
  Only hand-picked rough diamonds are used for CONTEXT DIAMOND and SPIRIT DIAMOND. They are procured by our own purchasing office at the world's largest diamond exchange in Antwerp.
  The manufacturing process demands the highest precision of both man and technology. The upper and lower sections of the diamond have to be cut exactly to within one half of an angular degree for the incomparable luminous reflection of CONTEXT DIAMOND and SPIRIT DIAMOND to become possible: we have patented our completely new combinations of angles worldwide.
