The book contains over 1,400 high-resolution color photomicrographs. Each image is accompanied by an explanatory caption detailing the host mineral, the type of inclusion, the lighting technique used, and the scientific significance of the visual scene. This makes the book an invaluable reference atlas; a gemologist looking at an unknown feature under a microscope can flip through the Photoatlas to find a matching visual profile.

In the world of gemology, understanding what lies inside a gemstone is often more crucial than its outward appearance. Inclusions—those tiny crystals, gas bubbles, or liquid fissures trapped inside a gemstone during its formation—are the "fingerprints" of nature. For decades, the undisputed bible for identifying these internal characteristics has been the .
The inner world of gemstones holds secrets that fascinate gemologists, jewelers, and collectors alike. Among the most legendary literature documenting this microscopic universe is the by Eduard J. Gübelin and John I. Koivula.
