Burmese Ruby Inclusions

Explore Burmese ruby inclusions in Hyperion, the Lotus Gemology inclusion database. Hyperion contains photomicrographs of inclusions and internal features in natural rubies from Myanmar (Burma), documented with information on treatment, lighting conditions, field of view, photographer and published references.

This cluster of crystals, cut through on the surface of this ruby from Mong Hsu, Myanmar, was identified as dolomite with Raman microscopy.
Nests of rutile silk needles, as depicted here, are a common inclusion in rubies from Myanmar’s Mogok stone tract.
Prior to heat treatment, most rubies from Mong Hsu, Myanmar display a deep blue core. Here it appears in a “V” shape.
Prior to heat treatment, most rubies from Mong Hsu, Myanmar display a deep blue core, as shown here in classic form.

Prior to heat treatment, most rubies from Mong Hsu, Myanmar display a deep blue core surrounded by layers of cottony diaspore silk, as shown here in classic form.

Solid inclusions are a relatively rare sight in rubies from Myanmar’s Mong Hsu area. This perfectly formed hexagonal prism cut through on the surface, not unexpectedly, turned out to be fluorapatite, as proven by micro Raman.

This star ruby is ready for its close-up. When cut in the right manner, some rubies and sapphires with rutile silk inclusions can display a “star,” a phenomenon known as asterism.
A light dusting of rutile silk in this 5.59 ct ruby can be spotted at high magnification. The features pictured provide evidence that this gem is unheated and hails from Myanmar’s (Burma’s) storied Mogok region. This inclusion scene is a unique identifying feature of the gem.
Triangular growth markings decorate the exterior of this rough ruby crystal.

Burmese ruby inclusions may include mineral crystals, rutile silk, healed fissures, fluid inclusions, negative crystals, 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 ruby and evaluating a possible Burmese origin.

Burmese Ruby Inclusion Photomicrographs

The Hyperion Burmese ruby gallery includes microscopic features documented in rubies from Myanmar (Burma). Each entry is accompanied by descriptive information and, where available, references to the gemological literature.

What Inclusions Can Reveal About Burmese Ruby

Inclusions are an important part of geographic origin determination in ruby. Their form, composition, orientation and associations can provide evidence that, when considered together with other gemological properties, may support or contradict a Burmese origin.

Hyperion combines inclusion photomicrography with supporting gemological information so that individual features can be compared with documented examples from Burmese rubies.
