Emerald Inclusions

Explore emerald inclusions in Hyperion, the Lotus Gemology inclusion database. Hyperion contains photomicrographs of inclusions and internal features in natural emerald, documented with information on geographic origin, treatment, lighting conditions, field of view, photographer and published references.

While comparatively rare, amphibole needles are a feature of some emeralds from Malysheva, Russia, as shown in this photomicrograph produced in polarized light. Specimen courtesy of Tsar Emeralds Corp.
When this emerald is illuminated with a longwave UV torch, chalky areas can be observed in the fissures. This is a sign that the fissures contain filler.
Colombian emeralds crystallize from a saline-based brine, remnants of which can be found as three-phase inclusions featuring jagged-edged liquid-filled pockets containing blocky crystals of halite (sodium chloride—rock salt).

In this resin-filled emerald, an yellow-orange flash can be seen in the filled fracture. This treatment helps to minimize the appearance of fissures.

Emerald inclusions may include mineral crystals, fluid inclusions, multiphase inclusions, healed fissures, growth features and other internal features formed during or after crystal growth. Such features are important to gemologists because they can provide evidence useful in identifying emerald, understanding its geological history, recognizing treatment and, in some cases, determining geographic origin.

Emerald Inclusion Photomicrographs

The Hyperion emerald gallery includes microscopic features found in emeralds from major deposits around the world. Each entry is accompanied by descriptive information and, where available, references to the gemological literature.

What Inclusions Can Reveal About Emerald

Inclusions are an important part of emerald identification. Their form, composition and associations can help gemologists distinguish natural emerald from synthetic material, recognize evidence of treatment, and study the geological environment in which the emerald formed.

Hyperion combines inclusion photomicrography with supporting gemological information so that individual features can be compared with documented examples from known emerald deposits.
