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.

A transparent zircon crystal stands out against a backdrop of undissolved rutile silk in this Mogok ruby.
Euhedral crystals are suspended amongst a cloud of rutile silk in this ruby from Myanmar’s Mogok stone tract.

A variety of crystals can be spotted in this inclusion scene. On the left is a crystal containing diaspore, on the right are transparent spinel crystals, and the dark crystal at the bottom is primary rutile.
This scene contained spinel crystals as well as CO2 inclusions.
A croissant-shaped calcite crystal is suspended in this ruby from Mogok, Myanmar. Calcite is a common inclusion in rubies from this locality.
This Mogok ruby contained an interesting inclusion scene. The three crystals on the left are mica, and the top right is garnet. In the background we can see undissolved rutile silk needles, a hallmark of this type of material.
While analysis with micro Raman did not yield conclusive results for this inclusion, it is likely a primary rutile crystal.
Several dark primary rutile crystals are visible in this Mogok ruby.
A variety of solid inclusions can be seen in this Myanmar (Burma) ruby. At the bottom we have a pair of transparent apatite crystals. At top left there is a cluster of dark primary rutile crystals, and at top center there are some small, transparent feldspar crystals.
These mica crystals, encapsulated in a ruby from Mogok, Myanmar (Burma), show a series of striations on their surfaces.
In the center of this scene in an untreated ruby from Mogok, Myanmar (Burma) we can see a pair of calcite crystals. Angular color zoning can also be observed.

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.
