The most precise sorting methods in the industry

A large inventory of precision-sorted excellent-make round diamonds
After polishing, each diamond is sorted according to four criteria: size, purity, color, and sieve-size.Sortoscopes and microscopes are used to pinpoint the slightest differences between each stone. We sort purity and color according to GIA standards and divide all purity-color combinations into six groups.

This precision sorting gives:

  • More than 10 size categories with 73 mm sieve sizes
  • 10 levels of purity
  • 21 different color tones
  • Over 4,000 sorted parcels in stock, each coded using our proprietary EZ Code
