As high quality gemmy materials directly from natural sources depleting over the years, gem treatments, using heat or other techniques, are very common in many gem materials nowadays.  This session focuses on methodology, results and detecting techniques of treatments on gem materials, including but not limited to: heat treatment, high-pressure-high-temperature treatment, radiation treatment, impregnation, ion implantation, microwave annealing, laser annealing, laser drilling, multilayer coating and so on.  Any other gemstone related subject is also welcome.

This website is specifically set up to facilitate the process of collecting manuscripts for the special issue of the Journal of Gems and Gemology.  Please use this website for submitting your manuscript.  Thank you!
