A melted crystal shines in a heated Thai/Cambodian ruby. These crystals begin life as solids, but are turned into glass by heat treatment. Because glass takes up less volume than a crystal, a frozen shrinkage bubble is often found in the glass. Note also the iridescence from the surrounding fingerprint, in shades of red and blue. This is because these are the two colors transmitted by ruby.

Search the Complete Hyperion Database
Natural 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, understanding its geological history, recognizing treatment and, in some cases, determining geographic origin.
Natural Ruby Inclusion Photomicrographs
The Hyperion natural ruby gallery includes microscopic features found in rubies from major deposits around the world. Each entry is accompanied by descriptive information and, where available, references to the gemological literature.
What Inclusions Can Reveal About Natural Ruby
Inclusions are an important part of ruby identification. Their form, composition, orientation and alteration can help gemologists distinguish natural ruby from synthetic material, recognize evidence of heat treatment, and study the geological environment in which the ruby formed.
Hyperion combines inclusion photomicrography with supporting gemological information so that individual features can be compared with documented examples from known ruby deposits.
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.
