Hmm. Well it seems to me that it must have a certain percentage of lead in it. For its size it is indeed surprisingly heavy, which makes me believe it has to be more than just glass. I doubt if it were it would have cost me $75, I'd think it would have been much cheaper. I'm beginning to wonder if the "bubbles" inside are actually just smaller round balls or beads that have been somehow inserted inside during production? I don't know but based on the cost of the item and its surprising weight, it has to have at least some percentage of lead in it. It's very doubtful that I was ripped off from such a store. They actually didn't know the prices or anything when I called them about it, when I got there they had them written on a piece of paper. I asked them over the phone what they were made of, so it's not like I specified that I wanted crystal. They had to look everything up from the consumer I'm guessing, and didn't tell me until afterwards that it was crystal, so I know she wasn't lying to me. Just makes it all the more confusing...
Even if it is leaded crystal/glass, and has just enough percentage of lead to be called "crystal", doesn't it still contain enough pure glass to have bubbles inside (if that's what they really are)?
