Large Vintage Poured Molded Glass Brooch...Stunning!

This brooch is very unique to say the least. It has four poured molded glass stones in varying shades of sherbet green. Within the mix are four gold petaled flowers with aurora borealis stones and three large emerald green stones of which two are givre. Please examine the pictures carefully. This brooch has heavy gold plating and solder pooling on the back to reinforce the strength of the brooch, it is extremely well made and has no signature. Possibly a Delizza and Elster designed for another company? The measurements are 2 3/4" high x 2" wide.
