ISO missing earring

Help me if you can, please It’s from the avon vintage emerald green & rose gold necklace set. The jewelry is second hand, and when I got in the car I realized I didn’t have the matching earring. I’m not sure what I’ll be willing to pay for the exact set or just one. I don’t need another necklace. I just need the earring(s). I might be interested in set of earrings with similar colors. It’s costume jewelry, so I’ll cackle if the price is too ridiculous. Comment below with offers
