Featured Need Help on Opalescent Candlesticks

Hello Board Buddies - I purchased these candlesticks at auction yesterday and can't seem to find anything about them. They measure about 7 3/4" high with a 3 3/8" base diameter. The base is flat. They seem to be a nice quality glass but they are some manufacturer's defects at the joins and the bubble placement is not the same. The only identifying clue is the label on the last picture. It came off in the cleaning process. The writing looks European I think. Any help towards an ID would be much appreciated. Thank you!

No clue, but that watery, opalescent look is beautiful!

 

Thank you, Ghopper1924. They were on a table in the back room and I just couldn't resist them!

Just try if objects glow in the dark.

 

The opaline part is non-reactive. The clear glass portion has a light green glow but not as strong as the glow I usually get from vaseline/canary or uranium glass pieces.

The glow fades thru time (depending on chemical concentrations applied on glassworks). Green glow - you may have the uranium glasswork. Uranium glass also fluoresces bright green under ultraviolet light and can register above background radiation on a sufficiently sensitive Geiger counter, although most pieces of uranium glass are considered to be harmless and only negligibly radioactive.
You got curiousity and appreciation of your possession. This is a guide knowing your collection. Just a little reminder to those who loves to collect porcelain and glass - one must be aware that the industry during certain times used radioactive materials to enhance luminiscence and flourescent color for beauty, elegance and mystic of the art in their business, please refer to these few weblinks for your indulgence - it will lead to the history of the object:

Looks like Tiffany glass to me. Some early Tiffany glass looked like yours. Though I am not 100% sure.

 

The opalescence reminds me of some Fry Glassware, but I don't know if they made candlesticks at all.
Very pretty.

 

Probably some type of Murano Glass---They are not old.

 

Thank you for your opinions folks. Nokita, thank you for the articles. I don't have much of a chemistry background though. Thanks for comments, billyd3us, but the quality just isn't there for Tiffany. Thanks too, Pearls. I searched Fry after your suggestion. They did make some beautiful candlesticks but nothing like this I'm afraid. Fenton, that was my original opinion, that they might be some type of Murano glass. I'll pursue that avenue further. Thanks again all. I really appreciate your time and assistance.
