Description
Identification of synthetic and treated diamonds cannot leave aside today the use of various spectroscopy techniques such as Raman, Photoluminescence (PL), FTIR, UV-Vis-NIR, Fluorescence, and others. Especially nowadays, the wide availability of cheap melee-size synthetic diamonds, very often mounted in jewelry, can pose a huge threat to the work of many operators of the diamond chain. In some cases, the differences between synthetic and naturals are so subtle that such techniques are mandatory for providing the correct identification. This workshop will provide an overview of the most used techniques and the related applications specifically for diamonds including hands-on practice about the most critical cases.
Mikko Åström is a gemologist FGA (with distinction), laboratory technician, and IT entrepreneur having more than 20 years of experience as a gemologist, head of the diploma courses of Gem-A teaching center at Helsinki and author of gemological articles, books, and course materials. He has worked extensively in the field of gemological spectroscopy, designing and inventing UV-VIS-NIR, Raman, PL, FTIR, and other advanced laboratory instruments.
