Advanced Gemmology

The Advanced Gemmology course, developed by the WGF (World Gem Foundation), is largely devoted to the imitations of gemstones, the different methods of manufacturing synthetic gems – as well as techniques to distinguish them from their natural counterparts – and the detection of the different treatments used to improve the appearance and/or value of gemstones.

Many topics are covered in this course: artificial gems and composites, methods used to manufacture synthetic gems including Verneuil, Czochralski, melting, hydrothermal, copper skull, zone fusion, horizontally oriented crystallization, HPHT, CVD, detonation, sublimation and modified Stöber, and the different characteristics to identify them. Treatments and techniques for improving gemstones will also be discussed, including heat treatment, surface and volume diffusion, lead glass fracture filling, filling of fractures with cobalt-doped lead glass (for sapphires), flux crack healing, methods of improving the purity of diamonds, HPHT treatment of diamonds, quench-crackling, surface modification, laser drilling, irradiation and scientific gem identification techniques.
