AGT Certification

The AGT Gemological & Astrological Certificate of
Authenticity & Description of Astral Aspects

Each Astral Gemstone Talisman is presented in an exotic wood or silk box and comes with the AGT Gemological and Astrological Certificate. The first page of each certificate shows a digital color photograph of the talisman, and gives the creation date and Astral Gemstone Talisman Collection serial number (see sample below).


The gemological description describes the “4 Cs,” viz., COLOR, CUT, CARAT WEIGHT & CLARITY…


  • Color is a description of the primary hue of a gem when viewed in indirect sunlight.
  • Cut describes the shape and style of a gem’s cutting and polishing.
  • Carat is weight of the gem (1 gm = 5 carats).
  • Clarity describes the extent to which a gem is free of flaws when viewed through 10x magnification (10x loupe) in dark field illumination. The clarity grade for every gem (in the AGT report) is expressed as a percentage of purity on a scale from 100% clean (0% flawed) to 0% clean (100% flawed).
