The HPHT treatment in diamonds is permanent Most HPHT treated diamonds are over 0.50 carat. The color enhanced diamonds with HPHT treatment are reaching in trade undetected and are being sold for a much higher price. The HPHT treated diamonds should cost less than similar natural diamonds.
The various gemological tests including high magnification, Conductometer, Geiger Counter, X Radiography, X Ray fluorescence, Ultraviolet fluorescence, X Ray diffraction, Infrared absorption spectroscopy, Photoluminescence techniques etc. may be used to identify a treated or irradiated diamonds.
The Federal Trade Commission states that HPHT treatment must be disclosed. General Electric uses a registration number and the letters. GE POL to inscribe their diamonds. The diamonds that are laser inscribed with words HPHT PROCESSED, IRRADIATED or a specific registered name are graded in gem testing laboratories. On detecting HPHT treated diamonds, GIA certifies the same as HPHT Annealed or Artificially Irradiated in their grading reports.
Astrologically speaking, only diamonds of natural origin should be used in astrology.
On doing treatment on Diamonds the energy gets liberated . The Diamond becomes free from its Soul, Pran, Atma and thus gets polluted or destroyed. Then it is charged with negative energy which is not useful in astrological application. The treated diamonds do not serve any purpose for astrological effects and gains.
