- Heart Shape Cut
- The Heart Shaped Cut is similar to the Pear Shape, except that there is a cleft at the top. In fact, often the reason cutters may choose a Heart Shape over a Pear may be that the rough diamond contained an inclusion located in the cleft. The skill of the cutter can make a great difference in the beauty of this cut. The shape appeal is especially important with Heart Cuts.
