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.

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.
Ilmenite silk in a sapphire from Myanmar’s Mogok Stone Tract.
An iridescent dagger lances the heart of this sapphire from Myanmar’s Mogok Stone Tract.
This lovely moiré pattern in a Burmese sapphire is a spectacular example of the photomicrographic art from the master, John Koivula.
Undissolved rutile silk in a Mogok sapphire. Such silk creates the stars in star sapphire and ruby.
Undissolved rutile silk in a Mogok sapphire. The intact nature of the silk demonstrates that this stone has not been subjected to high-temperature heat treatment.
Winged zircon crystal hovering within a sapphire from Myanmar’s Mogok Stone Tract.
Exsolved rutile silk is one of the classic inclusions found in Mogok sapphires.
Exsolved rutile silk opens a window into the heart of this unheated Mogok sapphire.
Undissolved rutile silk in a sapphire from Burma’s Mogok Stone Tract. Rutile silk in corundum forms in three directions at 60/120° in the plane of the basal pinacoid (perpendicular to the c axis).
This corroded crystal guest in a Burmese sapphire represents a protogenetic inclusion, one that existed before the sapphire itself. Secondary exsolved rutile is visible in the background.

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.
