Photoatlas of Inclusions In Gemstones Volume 1
The first volume of the Photoatlas of Inclusions in Gemstones is a landmark work that established the importance of inclusions as an aid to identifying gemstones and deepens our understanding of gems and their origins. This volume covers known microscopic characteristics of gem materials up to 1986. It includes over 1400 color photomicrographs that illustrate common features in gemstones from particular localities as well as various types of inclusions that help separate natural from synthetic gemstones.
