Though unsigned, I have no doubt that it was made by one of my favorite designers Countess Cis Zoltowska. Gorgeous collar necklace with matching clip on earrings. Gold tone setting with sparkling green and green Aurora Borealis stones. Typical hook and eye closure. Necklace measures 15.25″ long and 1.5″ wide. Matching earrings are 7/8″ in diameter. Excellent condition.
