Madagascar Spinel Inclusions
Explore Madagascar spinel inclusions in Hyperion, the Lotus Gemology inclusion database. Hyperion contains photomicrographs of inclusions and internal features in natural spinels from Myanmar (Burma), documented with information on treatment, lighting conditions, field of view, photographer and published references.
A crystal in this blue spinel is connected to a series of tubes.

A small white magnesite crystal (confirmed with micro Raman) displays an unusual circle around it in this spinel. We are currently unable to determine the natural of this circular inclusion around the magnesite.

Madagascar spinel 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 spinel and evaluating a possible Madagascar origin.
Madagascar Spinel Inclusion Photomicrographs
The Hyperion Madagascar spinel gallery includes microscopic features documented in spinels from Madagascar. Each entry is accompanied by descriptive information and, where available, references to the gemological literature.
What Inclusions Can Reveal About Madagascar Spinel
Inclusions are an important part of geographic origin determination in spinel. Their form, composition 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 spinels.
