Burmese Sapphire Inclusions

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

Striking iridescence in a healed fissure within an unheated Burmese sapphire.
A high-relief crystal shines in this unheated sapphire from Burma.
Etch marks of the surface of a natural (in the left portion of the photo), along with a fingerprint inclusion within the gem itself (right side of the photo). Note the identical pattern of the etch marks and the negative crystals within the fingerprint, both reflections of the underlying atomic symmetry.
Etch marks of the surface of a natural on a sapphire from Myanmar’s Mogok Stone Tract. The symmetry of the etch marks reveals the underlying atomic symmetry.
Etch marks of the surface of a natural (white areas in the upper left portion of the photo), along with a fingerprint inclusion within the gem itself (right side of the photo). Note the identical pattern of the etch marks and the negative crystals within the fingerprint, both reflections of the underlying atomic symmetry.
Etch marks of the surface of a natural on a sapphire from Myanmar’s Mogok Stone Tract. The symmetry of the etch marks reveals the underlying atomic symmetry.
A common feature of sapphires from Myanmar’s Mogok Stone Tract is fingerprints composed of well-formed negative crystals. The undamaged nature of the individual cavities is proof that this gem has not been subjected to high temperature heat treatment.

Burmese sapphire 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 sapphire and evaluating a possible Burmese origin.

Burmese Sapphire Inclusion Photomicrographs

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

What Inclusions Can Reveal About Burmese Sapphire

Inclusions are an important part of geographic origin determination in sapphire. 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 sapphires.
