Prof. Emmanuel Fritsch of the Institut des Matériaux, University of Nantes, France, reported on the Georaman 96 conference held in Nantes in June, which focused on the applications of Raman spectroscopy to geological materials. One session was dedicated to gemology, with many presentations centered on the use of Raman spectroscopy for identifying inclusions within gemstones.
