Featured Could these be Juliana?

They probably aren't, but the open backs are promising. I don't see any puddling though...

 

Quite pretty.

I found the earrings!!

 

The Juliana earrings utilize the same color stones but the configuration is different. Yours uses groupings of 4 stones, where the Juliana ones are in groups of 3, plus a single aurora stone for accent. Also, the clip back paddles are different. Yours are from the same era as the Juliana and just as attractive IMO.
Edit to add:- Also note the difference in the claw settings, the Juliana have the same 4 prong settings as the extension section of your necklace but your earrings have the multi-claw setting, I think yours are called a "dog tooth" setting.

 

Sandra, I see, yes, they are different. Oh well Thanks for your expertise.

 

You shouldn't feel down about your lovely set not being attributed to Juliana. In my opinion only, Juliana is over-rated and over-priced. At the same price points as Juliana, there are several companies that signed their costume jewelry and produced a superior product, I'm thinking of Schreiner, Sherman, and Kramer to name just a few.
Your set will stand on it's own merit and should attract a very nice price if you intend to sell.

 

Thank you Sandra <3 As a jewelry seller, I've always wanted to find a piece of Juliana. I do sell all my pieces, I'm allergic to almost every metal and so can't wear the lovely old pieces but I love collecting them.

 

Not only yours.
