I came across this linked vase again in searching for something else.  The more I see it the more I'm convinced my vase is old.  I don't know how old but it has a dark yellow glow under blacklight and the similarity of design with the linked vase is definitely there.

I read on a paperweight auction that Appert Freres pieces fluoresced yellow.  Appert Freres had links with Ernest Baptiste Leveille. 
This vase in the V&A has bubbles:

This one is listed as Eugene Rousseau and has enamels and bubbles:

I can't imagine any of those makers leaving a pontil mark unpolished however the base of mine is significantly indented so there would be no reason to polish. 
I am pretty sure mine is old - so possibly 'inspired' by perhaps?  I don't think it's studio glass because of the yellow glow under blacklight and the curious tint to the clear glass. However the enamels are black as compared to these examples which I think are dark red etc but not really black?

I also found these two on Alamy:

aaarggh, too late to add

The final two, the one on the right it says is made of quartz. Perhaps they meant the one on the left? But possibly that is the inspiration for many of these style of glass vases.
