HPHT is applied to the few diamonds that are not fully crystallized (\"premature diamonds\") when released from fiery, erupting volcanoes. The process is a carefully controlled, scientific procedure where high pressure and high temperature is used to finish what Nature started by applying the same atmospheric pressure (70,000 atmospheres) and temperature (3,682°F) conditions required to bring a diamond to its fully \"mature\" state. The HPHT process involves gemologists carefully positioning a diamond in a \"containment cube\" that is surrounded by heating mechanisms. The cube is then placed in a press to apply the same amount of pressure the earth creates when forming diamonds. As you can imagine, these multi-million dollar facilities are very sophisticated and are centered around an enormous computer controlled diamond press.\u003cbr\u003eHPHT mimics the exact same conditions that occur in the volcanic environments where diamonds are found. This process brings a candidate diamond to its most mature, desirable, colorless state. Mature diamonds are defined as those that show a highly coveted D, E, F, G or H color grade. The HPHT process simply finishes what nature started.\u003cbr\u003eThe 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 grade, it is important to note that these diamonds are not synthetics.\u003cbr\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"col-lg-12  col-md-12  col-sm-12  col-xs-12\"\u003e\u003cstrong\u003eOnly superior grade, Type 2 a, TLB and TTLB diamonds are candidates for HPHT.\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003eThese diamonds\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003emust\u003c\/strong\u003e\u003cspan\u003e \u003c\/span\u003ehave clarity grades of FL-VVS2 the highest clarities available.
