I do not find anything about glass filling in rubies though... Seems the info is a bit oldish and generalised?

You're right, Conny....but I'm always smitten with the pdfs that work like a book. I'm very easily entertained. :oops:

AGTA offers more timely eLearning (free to members). I love that they offer a student membership!

Probably they don't include lead glass filling in ruby treatments chapter because they don't consider such stones to be rubies, but composite materials (see "Gemstone Information Manual", last page), same as many labs and gemologists nowadays.
