Depends mostly on you. If your dress has many details—like lace and pearls, then maybe you can go with something small—simple gold, maybe with a tiny diamond. On the opposite, if your dress is very clean and minimal, with no extra details, then you can choose bigger sturdier earrings. But, the most important thing is how you feel when you wear them. They must feel right, like part of you and your style.

The most important thing is that everything must be in balance. A dress with many details like—beads, sparkle, and lace—may look better with small dainty earrings, so nothing is too much in your overall style. But if your dress is very simple and minimal, then you can choose long earrings that can add something special. Wedding dress and diamond earrings always look good. They are classic, like something from the past but always beautiful and timeless.

There is no need, but they should go well together. If your ring has a lot of details, like vintage or with small pave diamonds, then diamond earrings or minimal gold earrings can look nice. If your engagement ring has just one diamond, then maybe you can choose simple earrings, that are dainty and elegant. But, really, there are no rules. If you like the outcome together, then they are good.
