🔍 At IGI, we recognize the importance of accurately identifying lab-grown diamonds and differentiating them from natural stones. When it comes to handheld gemstone testers, understanding the differences between CVD and HPHT growth processes is crucial. 🔬 During the HPHT growth process, a metal catalyst is used, leaving behind remnants that can create conductivity within the lab-grown diamond. This conductivity can sometimes lead handheld electronic testers to mistake the diamond for moissanite
