The most popular size of diamond stud earrings is one carat TCW. This size is big enough being noticeable and matches a popular price range individuals have for diamond earrings. My most loved pair of 1 cttw studs are these stunners in a white gold martini setting from Blue Nile. https://flenzy.store/chic-hollow-heart-zircon-tassel-stud-earrings-in-18k-gold-finish/
