This design by DeLizza & Elster is called Venus Flames, circa 1970's. Other pieces in this series can be found in the latest book on Juliana jewelry by Knutson and Wacker.
This lovely brooch is set in gold tone metal and has a large central white with gold fluss oval cabochon. It is surrounded by milk glass white navettes and topaz colored rhinestones. The matching clip earrings have the same stones.
The set is in overall excellent condition, however upon very close inspection, I did notice a few very small chips on the edges of some of the navettes on the pin.
The pin measures 2 x 1.75 inches, the earrings are just over an inch long.
