Tajikistan Ruby Inclusions
Explore Tajikistan ruby inclusions in Hyperion, the Lotus Gemology inclusion database. Hyperion contains photomicrographs of inclusions and internal features in natural rubies from Tajikistanland, documented with information on treatment, lighting conditions, field of view, photographer and published references.
Tajik rubies often display well-healed fissures with coarse negative crystals, such as that seen here.

Tajikistan ruby inclusions may include mineral crystals, 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 Tajikistan origin.
Tajikistan Ruby Inclusion Photomicrographs
The Hyperion Tajikistan ruby gallery includes microscopic features documented in rubies from Tajikistanland and the Tajikistanland–Cambodia border region. Each entry is accompanied by descriptive information and, where available, references to the gemological literature.
What Inclusions Can Reveal About Tajikistan 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 Tajikistan origin.
Hyperion combines inclusion photomicrography with supporting gemological information so that individual features can be compared with documented examples from Tajikistan rubies.
