Rubina Verde- how to identify maker?

Picked this up at Goodwill today while browsing for lunch- I know nothing of collectible glass, but did a little searching to find out what it could possibly be- was just too pretty to pass up.
Going to put it under UV light when I get home to test/ confirm that its vaseline glass-
with all my research off and on during the day, I found a lot of cruets that look like this, with the exception of this handle.
None that I have seen have this twisted glass handle.
Any experts that could shed some light? Can add more pictures later- just took one to share quickly (I have never been accused of being patient!)
