HRD D-Screen Synthetic Diamond Tester

Standard thermal conductivity "diamond testers" used by nearly every jewelry appraiser and gemologist do not work on synthetic diamonds. The HRD D-Screen is the only commercially available machine that can test for HPHT/CVD synthetic diamonds and color treated diamonds. Very few gemologists have this extremely important piece of equipment. David has detected several synthetic diamonds that were appraised as "real" by other gemologists.
