Star Materials Micron Diamond Processes

The five S’s and the points of the Star!


SMS Quality Process 

  • Raw material undergoes several ‘regular’ tests.
  • In addition to these tests, SMS tests the purity of the diamond prior to processing to Micron specification.
  • Where diamond is found to have signs of static, static mitigation processing takes place.
  • Finally, the diamond is packed and sent for crushing.
  • Characteristics of crystal individually graded, allowing for accurate matching of samples.

Methods of observing size distribution

  • Area equivalent circle diameter is to place a circle over the particle and measure the diameter.
  • Feret Diameter is to place a rectangle over the particle and measure the shortest distance.
