Turquoise water?

Hi! My husband and I are planning our honeymoon in Italy in September (9/13-9/27). We are still shaping our itinerary but want to include somewhere that has Turquoise water beaches. There have been many posts about clear water but I’m looking for specifically turquoise water with either white sand or rocks. Would you mind being specific? Eg I think Puglia might have these types of waters but where specifically? Thank you so much!
