Thanks! I'm not really looking to manufacture or resell them, but that's something I will keep in mind.
This particular item was recently used as a very prominent prop on a popular science fiction television series. There are a lot of crazy people like me who want to collect or replicate things like this. We, much like you guys, obsess over tiny details and I thought I'd go to the experts to see if you could share any information on it.
We as a prop collecting community haven't had too much luck finding anything because we don't really know where to look. And we don't seem to be able to articulate exactly what we're looking for.
This does appear to be a "found object" (meaning they didn't have it made for the production but bought it off the shelf) and we believe it is a glass paperweight, a door stop or some kind of home decoration.
I have found a paperweight on ebay that matches this one exactly, however it is tinted orange and the listing doesn't make a lot of sense to me.
