Blue diamond of 0.92 carat under seal accompanied by its IGR certificate attesting: - Brilliant cut - Vivid Royal Blue - Clarity I2 - No fluorescence present - HPHT treaty The HPHT treatment of natural diamonds consists of placing the diamonds under high pressure and high temperature in order to bring them back to their original formation conditions and bring them back to their original colour, or to "heal" certain fractures. It is the only diamond treatment accepted today for certification by the largest laboratories such as G.I.A., being considered as a "natural" treatment that does not subject the stone to elements not naturally present during its formation, unlike irradiation or fracture filling.
