David,

    I too receive the Gem-A list. it is a great resource for what is
    happening in the world. The article on glass filled rubies is good at
    helping to understand some of the treating processes used. We need to
    know what is going to come across the bench and how to explain these
    things to our customers. At this point I do not think that I will
    ever put heat to  a supposedly safe stone again. The risk is becoming
    to great of hitting a treated stone, diamond or otherwise. 

    Thank you Dr. Ogden, who is behind the list.
