Madagascar Sapphire Inclusions

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

Fine texture clouds are common in Madagascar sapphires and give them a velvety, Kashmir-like appearance.
Sharp angular growth zoning defined by milky “texture” clouds. These texture clouds are composed of submicroscopic titanium-rich exsolved particles. Where they form, the gem is decolorized, as the titanium is no longer available to produce color. This phenomena was named “chromophore cannibalization” by photomicropgrapher John Koivula. Areas where the clouds are absent are a deep blue color.

Extremely sharp angular growth zoning in a Madagascar sapphire. At times the zoning is so sharp, it created iridescence via diffraction of visible light.

Madagascar 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 Madagascar origin.

Madagascar Sapphire Inclusion Photomicrographs

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

What Inclusions Can Reveal About Madagascar 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 Madagascar origin.

Hyperion combines inclusion photomicrography with supporting gemological information so that individual features can be compared with documented examples from Madagascar sapphires.
