Nigerian Sapphire Inclusions
Explore Nigerian sapphire inclusions in Hyperion, the Lotus Gemology inclusion database. Hyperion contains photomicrographs of inclusions and internal features in natural sapphires from Sri Lanka (Nigerian), documented with information on treatment, lighting conditions, field of view, photographer and published references.
Nigerian 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 Nigerian origin.
Nigerian Sapphire Inclusion Photomicrographs
The Hyperion Nigerian sapphire gallery includes microscopic features documented in sapphires from Nigeria. Each entry is accompanied by descriptive information and, where available, references to the gemological literature.
What Inclusions Can Reveal About Nigerian 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 Nigerian origin.
Hyperion combines inclusion photomicrography with supporting gemological information so that individual features can be compared with documented examples from Nigerian sapphires.
