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.

A brown, prismatic crystal, possibly tourmaline, is suspended inside of this schist-hosted emerald.
A cluster of crystals, likely mica, of various sizes and shapes is suspended in this Zambian emerald.
A cluster of crystals (likely mica) reaches the surface of this Zambian emerald. When exposed to the gentle heat of the microscope light, oil droplets leaked out at the boundary between the inclusions and the host.
This emerald contained a series of slender two-phase inclusions. Like a genie in a bottle, the bubble (probably carbon dioxide) trapped inside has likely resided there for millions of years.
The Emerald City. Fine tubes form a dramatic skyline in this gem.
Like ribbons, irregular negative crystals decorate the interior of this emerald.
A crystal (likely mica) with an iridescent surface can be seen in this emerald.
A bouquet of iridescent thin films can be observed in this emerald from Russia.
A Pollock-esque scene, in green. At high magnification, a cluster of iridescent thin films creates a burst of color in this Russian emerald.
A tourmaline rod (possibly fluor-dravite) and a few phlogopite mica crystals decorate the interior of this emerald from Zambia.
Two tourmaline crystals, one epigenetically stained with iron-oxides, are trapped with several blocky 2-phase inclusions in this Zambian emerald.
Iridescent thin films form a dramatic topographical scene in this emerald.

Search the Complete Hyperion Database

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.
