Treated Ruby Inclusions
Explore treated ruby inclusions in Hyperion, the Lotus Gemology inclusion database. Hyperion contains photomicrographs of inclusions and internal features in natural rubies that have undergone treatment, documented with information on geographic origin, treatment, lighting conditions, field of view, photographer and published references.

After this ruby grew, it was exposed to high pressure, causing certain planes of atoms to glide into a twinned position. This secondary “polysynthetic” twinning takes place along the rhombohedron faces and is common in many corundums. Twin planes cross at 86.1 and 93.9° angles.

Treatment can alter existing inclusions and produce new microscopic features in ruby. These may include changes to mineral inclusions, altered rutile silk, tension fractures, healed fissures, residues and other features associated with heating, fissure healing, glass filling and other treatment processes.
Treated Ruby Inclusion Photomicrographs
The Hyperion treated ruby gallery includes microscopic features documented in natural rubies subjected to treatment. Each entry identifies the recorded treatment and is accompanied by descriptive information and, where available, references to the gemological literature.
What Inclusions Can Reveal About Ruby Treatment
Microscopic examination is an important part of detecting treatment in ruby. The appearance and alteration of inclusions, fractures and growth features can provide evidence of treatment and, in some cases, information about the processes to which a ruby has been subjected.
Hyperion combines inclusion photomicrography with supporting gemological information so that treatment-related features can be compared with documented examples in natural ruby.
