This webinar gives an insight about the history of gemstone deposits, treatments, and development of synthetics. It then goes into the parallel development of ways to detect these new trends, and gives hints of what the appraiser or gemologist can do with standard instruments. Covered are a range of selected gems, among them ruby, sapphire, and emerald.
