Ringman,

    I have come into this conversation late so I do not know the
    original question but let me make everyone aware about glass
    fillers. 

    Any gemstone that is heat treated to improve the color and has
    fractures that break the surface has the potential to have a glass
    filler. 

    What actually happens is the flux used to protect the stone during
    the heat treatment melts and enters the cavity. This problem is most
    often found in rubies but could be found in other gemstones as well
    due to the process used.
