Description of Treatment:
Exerpt from Wikopedia: https://en.wikipedia.org/wiki/Ruby
Another treatment, which has become more frequent in recent years, is lead glass filling. Filling the fractures inside the ruby with lead glass (or a similar material) dramatically improves the transparency of the stone, making previously unsuitable rubies fit for applications in jewelry. The process is done in four steps:
If a color needs to be added, the glass powder can be "enhanced" with copper or other metal oxides as well as elements such as sodium, calcium, potassium etc.
The second heating process can be repeated three to four times, even applying different mixtures. When jewelry containing rubies is heated (for repairs) it should not be coated with boracic acid or any other substance, as this can etch the surface; it does not have to be "protected" like a diamond.
The treatment can identified by noting bubbles in cavities and fractures using a 10× loupe.
---The article gives an excellent description of the treatment process.
All Rubies have pores and microscopic fissures, with treated Rubies, these are cleaned and filled with glass.
Glass treatment produces cleaner appearance, fewer inclusions, better fire and color.
The durability of these stones has been outstanding.
This Ruby is guaranteed against breakage for one year (not to exceed the purchase price).
