Sergey Sivovolenko: “Quantitative Absorption Spectra for Diamond”

This video is from the Research Track of the 2018 GIA International Gemological Symposium. The Research Track presented the latest findings by Institute researchers and scientists respected across the industry and from around the world. This presentation is part of the theme, Gem Characterization. The study of gems should be conducted with advanced scientific instrumentation, a database of gemological information, a data-collection protocol and analytical standards of instrument calibration. Correct gem identification should be based on a variety of features of the gemstone being examined. Presentations will cover these methods and instrumentation.
