The SSEF Diamond Spotter GM190 allows for portable, quick and easy testing of colorless, pink and blue diamonds, polished or rough and loose or mounted, for possible HPHT treatment.
The Diamond Spotter is specially designed to show a green spot when viewed with Type II colorless diamonds (which might have been HPHT treated). The green spot means you should send the diamond for further testing by a lab. If there is no green spot, the colorless diamond has not been treated by HPHT. ItÃ¢â‚¬â„¢s that easy!
Use with a shortwave UV lamp (we suggest the GMUV193 or GMUV192).
