However, some general trends and tips are: Round earrings are more classic and versatile, as they can suit any face shape and outfit. They can also create a sense of harmony and balance, as they echo the natural shape of the earlobe.

For example, a single round stud earring with 0.10 carat total weight in white gold or a single stud earring with 0.25 carat total weight in a cluster of diamonds.

Square earrings can vary from sleek square studs to more intricate square frames or grids, depending on the shape and arrangement of stones. Ultimately, the best shape of earrings for guys are the ones that match their personality and style.
