Description
Implementation of modern spectroscopy in Gemology. Raman/PL, FTIR, UV-Vis-NIR, and fluorescence, the most used techniques are explained along with their major applications in the daily work of the gemological laboratory. Identification of synthetics and treatments, detection of elements like Copper in Paraiba Tourmaline or iron in Emeralds or Magmatic sapphires. Detection of spinel treatment by photoluminescence. Impregnation identification by fluorescence spectroscopy and FTIR Diamond types, their nitrogen aggregates and lattice defects. These are only some of the critical issues which will be covered and solved with the aid of the most common spectroscopic techniques used nowadays in the Gemlab.
Alberto Scarani is a Graduate Gemologist (IGI Antwerp), appraiser of the Chamber of Commerce, and Registered Expert of the Tribunal of Rome. With Mikko Åström founded in 2012 the M&A Gemological Instruments, now Magilabs, a company specialized in manufacturing advanced gemological instruments and developed Raman,/PL, UV-Vis-NIR, FTIR, and Fluorescence spectrometers specifically designed for gemology.
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.
