GIA iD100™ DiamondCheck
The GIA iD100™ combines advanced spectroscopic technology with GIA's 60 years of diamond and gemstone identification research to distinguish natural diamonds from laboratory-grown (HPHT and CVD) diamonds and diamond simulants.

  • Colorless to near-colorless diamond identification
  • Automatic identification with results in <2 seconds
  • Easy reading result with audio; "Pass" or "Refer" for further testing
  • Tests both mounted and loose diamonds 0.9mm or greater in diameter (approx. 0.005 carat)
GIA DiamondCheck™ is intended to examine colorless stones in the D-to-N range. It identifies natural, untreated diamonds and refers for further analysis stones that may be treated or synthetic. The system is based on the same technology and processes used at GIA.
