Vintage Costume Jewelry: Coro-nation

Clover Duette 1930s by HatstoFlats on Etsy

Coro is the epitome of "the every woman's jewelry."  Chances are, you've come across many pieces of vintage Coro jewelry as a seller, a collector, or a casual jewelry shopper.  There is a rich history behind this long running company.  Dating back to 1901, the company was started by Emanuel Cohn and Carl Rosenberger and became "Coro" in 1943. In the late 30's, the company was the largest producer of costume jewelry in Rhode Island, employing over 3500 people!  Check out Coro History at illusion jewels! 

One of my favorite companies to research is Coro costume jewelry, I just love looking through all the jewelry patents available to accurately date my Coro jewelry.  There are so many jewelry patents from Coro available for viewing here.  I can lose hours perusing them! I love to create little "wish lists" based on some of the patents. 

Some of the earliest jewelry marketed by Coro are the duettes.  Later Trifari followed suit by patenting "Clip Mates" but Coro started it all with the separable dress clips/brooch convertables.  Often figural and elegant in nature, these deco-styled beauties reigned in the 30s and 40s as high-end fashion accessories.
