Several glass factories made paperweights with this theme, but based on the profile and bottom treatment, I suspect this was made by Gentile Glass of Star City, West Virginia.
I saw your other posting, and can't see the bottom as clearly. Do the comparison. If they were made by the same hand, then investigate Gentile as the maker for that one as well. However, I have never seen a Gentile weight with that drawing. The aventurine suggest a Murano origin.
