Madagascar ruby inclusions may include mineral crystals, rutile silk, healed fissures, fluid inclusions, negative crystals, color zoning and other 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 Madagascar origin.
Madagascar Ruby Inclusion Photomicrographs
The Hyperion Madagascar ruby gallery includes microscopic features documented in rubies from Madagascar. Each entry is accompanied by descriptive information and, where available, references to the gemological literature.
What Inclusions Can Reveal About Madagascar 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 Madagascar origin.
Hyperion combines inclusion photomicrography with supporting gemological information so that individual features can be compared with documented examples from Madagascar 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.
