32 carats natural emerald?? 9k gold earrings

Bought these from an antique dealer in London England. He assured me that the stones are natural emeralds but I’m skeptical about it. Hence the great price. The stones are beautiful nonetheless and a they bear a substantial weight. Also set in 9k yellow gold fishhook style. I’m asking for the same price I paid for it. You can get them tested if you wish. Good luck.
