18k Solid Gold Emerald Hoop Huggie Earrings

Gorgeous bright colored emerald 18k yellow gold huggie hoop oval earrings. Really hard to capture emeralds in photos. Marked 750 AU. I thought these were slightly more than a 1/2 carat, but I’m wondering if the inside marking means they are more? I’m not a jeweler, just a jewelry obsessed person so bid accordingly. I can’t imagine anyone being disappointed. Weighs 3.3 grams with 22 emeralds. About .75” long with a secure hinged closure. Thanks for looking!
