Featured Antoinette gold-filled brooch/earrings

I was digging through my old jewelry that I collected years ago and came across this. Anyone have any information on this manufacturer? Googling brings up way too much extraneous stuff concerning Marie. Has the look of Halley’s comet jewelry from the 1910s IMHO, but it’s probably from the 1950s or 60s?
Thank you!

 

Oh, I want that, too. Screams fifties to me, the whole atomic space age thing.

 

Thank you!
I momentarily forgot about the whole atomic trend of the mid-century and was focused on the Halley's comet trend of the teens.

 

This listing attributes "Antoinette" to Coro. Not 100% sure, can't find much more information! Vintage CORO Teal Rhinestone Gold Floral Brooch...teal 12K - Etsy Canada

 

I hadn't heard of that possibility and checked out the link... BUT, it seems the seller simply "married" a Coro brooch with similar-in-appearance (but NOT the same) Antoinette earrings. I don't think the seller meant to imply that the Coro and Antoinette companies were linked, but I appreciate your effort to find info for me.

 

No problem! I know some companies like Coro had other names on their pieces, maybe design lines or something like that, so thought that was a possibility

 

Ok, once more with feeling! What about Anthony Creations Inc? Anthony Creations brooch with drop pendant | Collectors Weekly. Founder was Antonio Aquilino, his daughter was Antoinette.

 

That looks a good bet, from the construction.

 

According to this site Anthony Creations, Inc.:

Looks like. I had it pegged for North Attleboro/Rhode Island -made jewelry right off. Mid to late 50s,when those blue rhinestones were the hot color and were probably still around after the AB craze took hold.

 

Thanks all!
