In the last few years, several high-profile incidents of parcels salted with synthetic diamonds have put the industry on high alert. They have also spurred gemmologists and others to develop new tools for identifying lab-grown stones.
The goal of this article is to provide gemmologists, appraisers, dealers, and retailers with screening processes using standard instruments (i.e. ultraviolet lamp and microscope in combination with polariscope) to help identify origin, or at the very least, to flag suspected lab-grown diamonds for further testing at an advanced lab.
