PGS Lab was invited to speak at the annual National Pawnbrokers Association convention in Las Vegas. We delivered a presentation centered on synthetic diamonds, their growing market presence and the methods for properly identifying them. The presentation was well received and we're excitedly looking forward to our 2020 speaking engagements.
The laboratory was interviewed by the Chicago Tribune on the prevalence and market implications of synthetic, man-made diamonds. We discussed some of the lab's methods for detection and disclosure of these products.
