Actually, it does looks a lot like some of the Royal Crest paperweights which are around at the moment, some of which have very nice bubbles, like yours. I don't know if any of them have aventurine in though :?
And if I hear one more person tell me how the Perth Conference was so absolutely fantastic I think I'm really going to cry! :x :cry:
