*What Is High Pressure High Temperature (HPHT) Color Treatment?
HPHT stands for high pressure and high temperature. It is a method of applying HPHT to those diamonds that are not fully crystallized ("premature diamonds") when released from fiery, erupting volcanoes. The HPHT process is a scientific procedure that is carefully controlled. The HPHT process is used to finish what nature started by applying 70,000 atmospheres (the same atmospheric pressure that a diamond gets in the ground) at temperatures up to 3,700°F.

Meeting these conditions will bring a diamond to its fully "mature" state. The HPHT process involves the careful positioning of a diamond by a highly trained gemologist into a "containment cube" that is surrounded by heating mechanisms. The cube is then placed in a press to apply the same amount of pressure that the earth creates when forming diamonds. This process brings the diamond to its most mature, desirable, colorless state. Mature diamonds are defined as those that have D, E, F, G or H color grades or fancy colors such as blues, pinks and greens. The HPHT process simply finishes what nature started.

The HPHT diamond maturation process is permanent. Even though heat and pressure is applied to bring a natural, high clarity, top light brown (TLB) or top, top light brown (TTLB) to a white color or fancy color grade, it is important to note that these diamonds are not synthetics and are 100% natural diamonds. Diamonds that finish in the pink or blue tones are extremely rare, even with the HPHT process.
