who made this unmarked Dump paperweight depicting sea creature

Looks pretty cool but it can be difficult, they are still produced and sent from China, you can find some on aliexpress and similar sites. Just google, Glass paperweight medusa or jellyfish and you will find quite a few examples. Or just look here: http://totalpict.com/jelly%20fish%20paperweight I hope it's fine to post as doesn't look like commercial site.

Thanks redware, very hard to tell which is which as there is quite a lot of this jellyfish glass from china on the market oh dear me lol... i saw one listed made by murano couple of days back... but different from this one.. i will try and find a paperweight collector online and show him or her this piece..

and i forgot to add this piece is very heavy
