The GIA (Gemological Institute of America) has updated its iD100 diamond-testing device so it can now distinguish natural pinks from laboratory-grown (HPHT and CVD) diamonds and diamond simulants.

According to IDEX Online, the GIA has also made a further improvement, releasing a free update to the GIA iD100 software “with the expanded capability to screen blue-to-green and brown diamonds”. The new and improved software costs $249 for current owners but comes pre-installed on new devices.

Tom Moses, GIA executive vice president and chief laboratory and research officer commented: “These two significant improvements make proper identification of laboratory-grown diamonds more easily accessible to retailers and manufacturers around the world by expanding capabilities of the GIA iD100. This is part of our mission to ensure the public trust in gems and jewelry”.
