Green Diamonds Guide

Green diamonds have been found in kimberlite-hosted deposits and secondary alluvial sediments in nearly every diamond-producing country. However, certain locations consistently yield more of these valuable stones.

In the past decade, most green diamonds observed have been yellow-green or pure green. These are followed by those with grey or brown modifiers and those containing blue components. These differing colour groupings correlate, to some extent, to four primary types of atomic-level defect arrangements found in natural diamonds: GR1, H3, hydrogen, and nickel defects.
