STUNNING necklace and earrings set!

AWESOME piece that I never had the occasion to wear! The bronze-patina contrasts beautifully with the green stones. I am unsure of the metal composition but this is a costume piece so I’m certain it is NOT gold or silver. The earrings are from a different collection but I felt that they matched enough to be included 😊. Please ask any questions! Measurements: Necklace is approx. 19” in circumference and not adjustable. Earrings are 2.5” long. Thanks for looking! 🍁🍂
