The 4C’s of a diamond are Colour, Clarity, Cut and Carat. The 5th C that most Chemical Composition. The composition of Diamonds is essentially that of Nitrogen & Boron impurities that occur during the formation. Out of 100% only 2% diamonds. We are proud to say that all Ethereal Green Diamonds are type IIa. examples of type IIa mined diamonds. Type IIa diamonds are very rare and they that are available in the market.
TYPE I
Ia diamonds contain Nitrogen (N) atoms in clusters. Approximately 95% of natural diamonds are type Ia diamonds.
Ib diamonds contain Nitrogen (N)atoms as isolated atoms instead of clusters.
Ia
With aggregated (N) pairs
Ib
Isolated single (N) impurities
