If you can afford it I'm always for 18 ct Gold . If your budget is tighter you go well with 14 ct. But never go below. 375 and 333 is crap and should not be allowed that this is called gold. I sometimes work with 900/000 Gold and even finegold. That's compatible with everyday except as a ring. It depends of the form and your lifestyle if it's for everyday. 🌞😊

thank you for your insight!
