EUC Sz6.5 10k YG 1/4CT GREEN CZ? Celestial/Abstract art deco Crescent Moon Ring

Preowned-vintage Unsure of age. I love it but I need to let it go Size 6.5 Marked 10KS (the “s” is for “stamped”, a letter often used in US made rings) 10kt solid yellow gold Marked CZ A 4mm round brilliant cut green/yellow gemstone, that has several inclusions. I am not sure if it is the actual original cz stone for the setting or if it was replaced with a real stone. CZ are supposed to be completely flawless. This is not. See photos Possible stone types other than cz are peridot spinel or garnet (maybe demantoid). Could be moldavite. It does have a slight fluorescence in black light (see photo) which is common in peridot and also spinel. Spinel would shine a bit more pink. Selling as is because I have no idea what this is. It could be a moldavite or demantoid garnet. It could be a deep fake cubic zirconia, they DO MAKE some with inclusions on purpose An open work crescent moon shape setting 10mm* top/bottom and 7.5mm* across (including crescent) Beautiful flat surface/rounded/domed band *caliper was messed up redid measurements** Band is 6mm wide on smaller side and 8mm on larger side and 1.9mm wide at base Setting sits 4.5mm** tall and band is @1mm thick at base Minimilistic, modernistic Elegant Art deco Perfect for daily wear.
