A modification of the popular brilliant cut, a heart-shaped cut diamond features a
cleft (between the lobes) and wings, which sweep to a point, echoing the
silhouette of a heart. The length to width ratio of a classic heart-shape cut
diamond is 1, and most heart shaped diamonds should be at least 0.5 carats —
any smaller and it becomes difficult to see the cleft and point. The cut of a heart
shape does, however, mask inclusions, so can be cut from a diamond of a lower
clarity grade than a brilliant cut diamond.
