The above were quick points to explain what glass filled rubies are. Lets go into more details to explain:

A natural ruby could be opaque, full of inclusions or even pink in color, before they treat it. The real treatment comes when they completely change the look from the opaque, pink colored natural ruby to a semi transparent reddish color glass filled ruby. They take the natural ruby, mix a few “unknown” chemicals, heat at high temperatures so most included crystals but the ruby starts melting, to dissolve in the ruby and make the stone a more valuable one. This is the basics of a glass filled ruby.
