Treated Emerald Inclusions

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

Afghan emeralds often contain cavities with multiple phases, such as this example in the center that shows four different crystals and two different gas bubbles.
Within this emerald, numerous cavities contain liquid, gas and as many as four different solid phases.
This fascinating multiphase inclusion shows an unusual sawtooth pattern on the long edges. Many of the cavities contain liquid, gas and as many as four different solid phases.
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.

Treatment can alter existing inclusions and produce new microscopic features in emerald. These may include changes to fractures, fissures, fluid inclusions, residues and other internal features associated with fissure filling and other treatment processes.

Treated Emerald Inclusion Photomicrographs

The Hyperion treated emerald gallery includes microscopic features documented in natural emeralds subjected to treatment. Each entry identifies the recorded treatment and is accompanied by descriptive information and, where available, references to the gemological literature.

What Inclusions Can Reveal About Emerald Treatment

Microscopic examination is an important part of detecting treatment in emerald. The appearance of fractures, fissures, fillers and associated internal features can provide evidence of treatment and, in some cases, information about the processes to which an emerald has been subjected.

Hyperion combines inclusion photomicrography with supporting gemological information so that treatment-related features can be compared with documented examples in natural emerald.
