Mozambique Ruby Inclusions
Explore Mozambique ruby inclusions in Hyperion, the Lotus Gemology inclusion database. Hyperion contains photomicrographs of inclusions and internal features in natural rubies from Mozambique, documented with information on treatment, lighting conditions, field of view, photographer and published references.
This spall mark, an irregularity on the surface of the ruby, was a result of heat treatment.

Mozambique 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 Mozambique origin.
Mozambique Ruby Inclusion Photomicrographs
The Hyperion Mozambique ruby gallery includes microscopic features documented in rubies from Mozambique. Each entry is accompanied by descriptive information and, where available, references to the gemological literature.
What Inclusions Can Reveal About Mozambique 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 Mozambique origin.
Hyperion combines inclusion photomicrography with supporting gemological information so that individual features can be compared with documented examples from Mozambique rubies.
About Hyperion
Hyperion is the Lotus Gemology searchable inclusion database. It allows users to browse gemstone inclusions by gem type, geographic origin, treatment and keyword.
