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 lone zircon crystal can be observed in this Mogok ruby.
A mica crystal is ensconced in a cluster of rutile silk needles in this unreated Mogok ruby.
Micro Raman identified this crystal, trapped in a ruby host, as spinel.
This Myanmar ruby contained a striking cluster of angular crystals. Analysis with micro Raman revealed that they are spinel.
In this inclusion scene in a Mogok ruby, we can view a transparent scapolite crystal.
This large, transparent crystal is suspended in a ruby from Myanmar’s Mogok stone tract. In crossed polars, as shown here, we can interference colors that suggest the crystal is doubly refractive. Micro Raman analysis identified the inclusion as titanite (sphene).
This large, transparent crystal is suspended in a ruby from Myanmar’s Mogok stone tract. Micro Raman analysis identified it as sphene.
A cluster of calcite crystals, identified with micro Raman, is suspended in this ruby from Myanmar. Calcite is a common inclusion in ruby from the Mogok area.
Several transparent crystals are present in this inclusion scene, shown here between crossed polars. The interference colors we see demonstrate that the crystals are doubly refractive. Analysis with micro Raman identified these crystals as calcite.
Several transparent crystals are present in this inclusion scene, shown here with dark field illumination. Analysis with micro Raman identified these crystals as calcite.
Several transparent crystals are present in this inclusion scene, shown here with light field illumination. Analysis with micro Raman identified these crystals as calcite.
A cluster of transparent calcite crystals are visible in this ruby from Myanmar.

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.
