Hi, welcome to the Board.
Please be patient. It can take time for people to come up with responses, especially for items that are not as easily recognised as others.
Personally, my first thought about your weight is that it might be Murano, but could be Czechoslavakian (i.e. a modern version of typical older "Bohemain" weights of this style). But I don't know for sure so please do not quote me on that.
The best sales descriptions for items that are not easily recognised are those that simply describe what can be seen. For example, "dome-shaped paperweight with three stylistic flowers in a pot all set within a covering of equally spaced air bubbles".
