This brooch felt special the moment I picked it up. Excellent quality and blinding blue AB stones. I've listed it twice with no takers, but a search of the "Is It Juliana?" website turned up a square one with a lot of similar characteristics. If it is Juliana, I think it would help sell it the next time I list. What do you think? I also want to thank Karla and Paula for providing a valuable resource for the study of this amazing jewelry! The search feature is a tremendous help!
The rivets looks right.

I can't tell for sure, but I think I see a couple of the small chatons on the outside edge with the three prongs.
It is a pretty brooch. I can't say for sure, but think it has great possiblities. 
Right you are, OCN. There is a raised tier in the center that would explain the rivets. I'm asking about this brooch because after doing a search for blue brooches on the above mentioned site, a square one with similar stones and construction popped up on the first page. I was a bit surprised because I was thinking my brooch might have been unsigned Weiss, but after seeing the one on the website... ? Thanks for the observation!
times, thanks so much for responding to this thread and providing confirmation on the brooch! If it weren't for the "Is It Juliana" website, I don't think I would have persued this 
. Sandy and OCN, thanks so much for providing your knowledge, experience and willingness to help a fellow joolie. I want to be one of you when I grow up! And for all those who didn't bid on this the first two times, the price just went up! LOL!
