PHOTOATLAS OF INCLUSIONS IN GEMSTONES 2

Photoatlas of Inclusions in Gemstones – Volume 2

With Volume 2, the Photoatlas of Inclusions in Gemstones series delves even deeper into the field of gemological analysis. Published nearly twenty years after the first volume, it greatly expands the photographic documentation and approaches the study of inclusions with a more analytical and diagnostic approach.

The book opens with an introductory section dedicated to the definition of inclusions, their history, and their value in the study of gems. This is followed by a substantial thematic section dedicated to inclusions and the microscope, inclusion analysis techniques, and the unique phenomenon of "inclusions within inclusions."

A significant section is dedicated to the characteristics that can make an inclusion diagnostic. The book explores the diagnostic colors of included minerals, the morphology of inclusions, fluid inclusions, and the relationship between microscopic characteristics and the geological context of the gem.

The main part of the volume is organized by host material, allowing direct access to the inclusions associated with different gems. Covered are:

Amber, beryl, chalcedony, chrysoberyl, feldspar, garnet, opal, peridot, quartz, spinel, topaz, tourmaline, zircon, and zoisite.

For each material, numerous internal characteristics observable under the microscope are presented, with particular attention to elements useful for the identification, characterization, origin, and recognition of natural and synthetic materials.

Volume 2 is therefore particularly useful when you want to move from the simple observation of a beautiful inclusion to its gemological interpretation, learning to evaluate shape, color, mineralogical associations, fluids, growth structures, and their relationship to gem formation.

A fundamental resource for those who work daily with the gemological microscope and require a vast photographic repertoire for comparison.

Ideal for: gemologists, gemological laboratories, advanced students, researchers, collectors, and gem identification professionals.
