This brooch is an exquisite example of DuJay's jewelry from the 1950's when they switched their focus from the figurals of the 1930's and 40's to produce work that emulated the fine jewelry of the period. The synthetic spinels are bead-set and prong-set just like fine jewelry in rhodium-plated sterling settings. The spinels are open-backed and you have to look very closely on the back to see the mark of "sterling" to realize that this is not "fine" jewelry.
Even when it was new DuJay jewelry was expensive: an article from 1957 that I found online states that a necklace sold for $500, a fortune at that time. Judging by the quality of this brooch it is easy to see why their jewelry is so coveted and costly.
