Please help in identifying this gorgeous vintage brooch.

I have been searching for the maker of this beautiful vintage brooch.  If you look at the back you will see these "support pieces" within.  I cannot find any makers using this technique.  Perhaps one of you out there can help me.  The brooch measures about 2" each way.

Thank you in advance for your knowledge and assistance!

I’m also curious. I’ve seen a few like this on EBay

I found this one up for sale on eBay but they do not seem to know either.

From what it looks like via photos, could be Austria and stones are glass. Your brooch is a better construction and the use of a stabilizing bar shows good workmanship.  Prong settings and pie plate bezel settings, great piece!

     However it would take more research to pinpoint the maker of this piece without signage. I would start with Austrian costume jewelry makers but keep in mind this could take time. It's listable just the way it is, focus on the better construction and if you need help with keywords let us know! Silver

@wastingtime101 thanks for the tag.
