Mono crystal diamonds
Synthetic Diamonds for Industrial Use

 

If your production cycle includes all the stages from rough crystal till the final product, our lab-grown single monocrystals are reasonable for you. We can provide all the necessary service connected with buying rough crystals:

  • stable quality
  • big choice
  • guaranteed volumes

Crystals’ description

  • COLOR
    Currently New Age Diamonds offers crystals of orange color (synthetic crystal of Type Ib, containing approximately 100 ppm nitrogen).
  • SIZE
    0.2 – 3.0 carats
  • SHAPE
1. Oсtahedron topped perpendicular to the axis L4.

Pictures of rough crystal:

2. Oсtahedron topped perpendicular to the axis L4 with blunt planes of a cube or rhombi dodecahedron.

 

  • Chemical and physical properties
Our synthetic monocrystal diamonds are useful across many fields of industry: medicine, machining, test & measurement instruments, automotive industry, optoelectronics, tool-and-die industry, watch and jewellery production. Such a diversified application is based on synthetic diamond properties what are presents in the table below.
