half moon cut diamondsThe early diamond cutters shaped half moons diamonds from broken rounds and ovals. The challenge for the diamond cutter was not only cutting the stones to the same proportions but also from finding broken stones with the same color. Today the big demand for half moon shaped diamonds requires that cutters cut large numbers of half moon diamonds in various shapes, colors, and sizes. Then sorters find matched pairs that are kept together to be sold as side stones.
