Vietnamese Spinel Inclusions
Explore Vietnamese 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.

Vietnamese 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 Vietnamese origin.
Vietnamese Spinel Inclusion Photomicrographs
The Hyperion Vietnamese spinel gallery includes microscopic features documented in spinels from Myanmar (Burma). Each entry is accompanied by descriptive information and, where available, references to the gemological literature.
What Inclusions Can Reveal About Vietnamese 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 Vietnamese origin.
Hyperion combines inclusion photomicrography with supporting gemological information so that individual features can be compared with documented examples from Vietnamese spinels.
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.
