Photoatlas Volume 3, the final volume in the highly praised series, Photoatlas of Inclusions in Gemstones, focuses on inclusions in the major commercial gems (diamonds, rubies, sapphires, and emeralds) and inclusions in rare and unusual host materials, such as ekanite and taaffeite. This last book in the Photoatlas library concludes the 35-year collaboration of the renowned gemological authorities, E.J. Gübelin and J.I. Koivula. With the completion of Volume 3, Gübelin and Koivula have provided gemologists with the complete, authoritative photomicrographic reference volumes on inclusions in gemstones.
