A 3-carat oval diamond is an elongated shape, making it appear larger face up and in visual impact than its actual carat weight. This is one of the most popular diamond choices currently, as it is also a practical choice; it allows the wearer’s fingers to look longer and more flattering. Prioritise the cut of the shape for a brilliant shine, which helps avoid the bow-tie effect. A 3-carat is definitely going to look like a diamond that will steal the spotlight with its large presence on the finger.
