Gem Testing Device

With the growing availability of synthetic diamonds in the marketplace, full disclosure and confidence in knowing what you are buying is now more important than ever. GIA has developed a sophisticated and easy-to-operate desktop instrument to screen for these stones. The GIA iD100TM combines advanced spectroscopic technology with GIA’s 60 years of diamond and gemstone identification research to distinguish natural diamonds from synthetic (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 0.9 mm or greater in diameter (approx. 0.005 carat)
