Verneuil (Flame Fushion) Synthetic Ruby Inclusions

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

On rare occasions, we encounter synthetic gems that have been subjected to heat or diffusion treatment. a healed fissure with bubbly, rounded channels and concentration of diffused color around a pit in a diffusion-treated synthetic ruby.
On rare occasions, we encounter synthetic gems that have been subjected to heat or diffusion treatment. Here we see concentration of diffused color around pits in a diffusion-treated synthetic ruby.
On rare occasions, we encounter synthetic gems that have been subjected to heat or diffusion treatment. Here we see crackling at the surface of a diffusion-treated synthetic ruby.
On rare occasions, we encounter synthetic gems that have been subjected to heat or diffusion treatment. Here we see soap-scum like inclusions and gas bubbles just under the surface in a synthetic diffusion-treated ruby.
On rare occasions, we encounter synthetic gems that have been subjected to heat or diffusion treatment. Here we see pinpoint inclusions in a diffusion-treated synthetic ruby.
The curved striae in this synthetic ruby become clear when the stone is viewed under shortwave ultraviolet illumination. Between the striae streams of gas bubbles can also be observed.
While straight growth zoning is often seen as a sign that corundum is natural, this is not always. This flux synthetic ruby displays sharp straight growth zoning.
Whitish, flux filled cavities in a flux synthetic ruby display a melted appearance.
A string of small flux filled cavities stands out in this flux synthetic ruby.
The curved striae and gas bubbles present here are a tell-tale sign that this ruby is a Verneuil synthetic.
Curved striae reveal the true nature of this Verneuil flame fusion synthetic ruby.
Upon perfunctory observation, the healed fissures suggest that this ruby is heated, but closer observation reveals curved striae, proving that the stone is a quench crackled synthetic ruby.

Verneuil (Flame Fushion) synthetic ruby inclusions may include curved striae, curved color banding, gas bubbles, healed fissures, Plato lines, twinning, 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.

Verneuil (Flame Fushion) Synthetic Ruby Inclusion Photomicrographs

The Hyperion ruby gallery includes microscopic features found in rubies from major deposits around the world, as well as synthetic rubies. Each entry is accompanied by descriptive information and, where available, references to the gemological literature.

What Inclusions Can Reveal About Verneuil (Flame Fushion) Synthetic Ruby

Inclusions are an important part of ruby identification. Their form, composition, orientation and alteration can help gemologists distinguish natural ruby from Verneuil 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 natural ruby deposits and synthetic rubies.
