The modified brilliant-cut heart shaped diamond is a unique and unmistakable symbol of love. Heart shaped diamonds are very popular in solitaire pendants as well as rings. When choosing a heart, symmetry is a very important characteristic, since it is critical that the two halves of the heart are identical. The cleft (between the two lobes) should be sharp and distinct, and the wings (the sides as they curve down to the point) should have a very slightly rounded shape. The heart is the ultimate symbol of love. The unique look of the heart-shaped diamond helps make it a distinctive choice for a variety of diamond jewelry.
