The red stones are either pastes or garnets, if they scratch easily as you have noted, probably pastes, but that depends upon what they were scratched with, I'd get them into good directed light and use a jeweller's loupe on these stones, try to find inclusions in them, if you find inclusions the probability could be that they are garnets.

I believe what Thomas was saying is that the stones scratched the glass, not the other way around. I suspect they are more likely garnets than rubies, but probably real gemstones.
