The ultimate symbol of love, the romantic Heart shape is a variation of the round brilliant cut diamond. This ultimate symbol of romance is essentially a pear-shaped diamond with a cleft at the top. The skill of the cutter determines the beauty of the cut. Look for a stone with an even shape and a well-defined outline.
Length to width ratio: A heart-shaped stone is usually proportioned with equal length and width, approximating a ratio of 1:1. A length to width ratio of between 0.90:1 and 1.15:1 is preferred. The ratio should not fall below 0.80:1 or exceed 1.20:1
