The heart-shaped diamond is the most romantic of diamond shapes. It is similar to the Pear shape, but has a cleft in the rounded end that forms the lobes of the heart. Important considerations when choosing a Heart shape diamond are its symmetry, shape definition and outline, and the roundness of the lobes which should be rounded and clearly defined. A moderate bow tie formation at the center of the diamond is beneficial as it improves contrast brilliance and face up beauty of the diamond. Heart-shaped diamonds should be mounted in special settings with five prongs: two at the lobes of the heart, two on the sides of the heart, and a V-shaped prong to protect the point of the heart.
