Lead glass-filled rubies represent material that is heavily
treated to improve transparency. The treatment is highly unstable, resulting in
stones that can be easily damaged beyond repair. The material is relatively
easy to identify using a gemological microscope or jeweler's 10x loupe.
Tell-tale signs include: a flash-effect, large gas bubbles in a stone's
cavities, or flattened bubbles confined to wide fractures filled with glass.
Avoid any jewelry repair procedure and keep the material out of solvents, including
basic household cleaning solutions. Sometimes called composite ruby, hybrid
ruby, ruby with glass, or a host of other names, GIA considers some of this
material so heavily treated that it does not warrant being called ruby at all,
but rather a manufactured product.
To gain a deeper understanding of this material, read
"A Discussion on Ruby-Glass Composites & Their Potential Impact on the
Nomenclature in use for Fracture-Filled or Clarity Enhanced Stones in
General" (February 2012).
