Gold Kings buying advice
Follow the calibration and testing instructions carefully. Several materials can share similar responses. The PGT II does not distinguish diamond from moissanite or establish natural versus laboratory-grown origin. When an identification affects a valuable purchase or sale, have a qualified gemologist resolve the remaining uncertainty.
