To an Everlasting Marriage Diamonds 4 C's of Diamond Quality - Four characteristics that determine the quality of a diamond.
Many people confuse cut with the shape of a diamond.
Most diamonds are cut with a full 58 facets, and a good cut, or make, has more scintillation, more sparkle. The shape of the diamond, however, is largely a matter of personal preference and does not affect the value per se. It is the work of a master cutter that allows the diamond to be cut in such a way as to permit the maximum amount of light to be reflected through the diamond, and that's a great reflection on you. It is the cut that enables a diamond to make the best use of light. When a diamond is cut to good proportions, light is reflected from one facet to another and then dispersed through the top of the stone.
