This synthetic pink sapphire was fractured and then appeared to have been soaked in an iron-rich solution to created orange stains in the fissures, thus simulating padparadscha. The stains developed unusual dendritic patterns, as seen here. Chemical analysis also reveal traces of lead in the fissures.

The stains developed unusual dendritic patterns, as seen here. This fissure also shows an unusual shiny, glossy appearance. Chemical analysis also reveal traces of lead in the fissures.

Twin plane at one end of an unusual synthetic pink sapphire with artificial orange stains and dendrite patterned in induced fissures. Fine needles were seen along this twin plane and could easily cause a gemologist to reach the conclusion that the stone was natural.

With magnification, curved straie can be seen in this piece of Verneuil flame-fusion synthetic sapphire that was masquerading as a piece of natural rough.
This piece of Verneuil flame fusion synthetic sapphire was treated to make it look like a natural stone. However, the charade is over when the stone is viewed under shortwave ultraviolet light: it displays a chalky fluorescence that is seen in many Verneuil synthetics. (Note that natural stones may also display a chalky fluorescence, but it is usually in a zoned pattern.)
At first glance this Verneuil flame fusion synthetic pink sapphire makes for a convincing piece of natural sapphire rough. The stone has been treated to have a rough surface, complete with naturals with residues inside them meant to look like dirt or matrix. Substances such as shoe polish may be used on the outside of synthetic “rough” to make it look like natural material.

Sharp angular growth zoning, which is typical in Madagascar sapphire. This can help separate natural stones from Verneuil flame fusion synthetics, which have curved color banding.
