The identification of natural, man-made and treated diamonds has been the principal focus of the gem research program at GIA for more than 60 years. This is a group of natural colored diamonds ( to cts). Only superior grade, Type 2 a, TLB and TTLB diamonds are candidates for HPHT.

These diamonds must have clarity grades of FL-VVS2 the highest clarities available, because the extreme pressure and temperature can cause diamonds with inclusions or fractures to explode during the process. NOTE: HPHT diamonds are not treated diamonds. Treated Diamonds Diamonds with imperfections, e.g.

cracks or black pinpoints, are less valuable than those without. Some manufacturers have worked to give nature a helping hand by using new techniques to improve the appearance of natural (but imperfect) diamonds.Diamonds treated to become colorless are all Type IIa and owe their marring color to structural defects that arose during crystal growth, known as plastic deformations, rather than to interstitial nitrogen impurities as is the case in most diamonds with brown color.

HPHT treatment is believed to repair these deformations, and thus whiten the stone.
