Cut likely is the most controversial element of the diamond-buying process.
Cut is different from shape as it refers to proportion, facet arrangement, finish, symmetry and polish. There is a faction within the jewelry industry that is dogmatic in its cut parameters. There is also a faction that insists that “ideal” cut diamonds are the only ones worth buying. In fact, the GIA recently concluded an exhaustive study of diamond cutting and determined that there are numerous combinations of facet arrangement and proportions that will yield a beautiful diamond. In my opinion, the concept of “ideal” cut diamonds is a function of great marketing. Looking at several diamonds will help you decide for yourself what cut details are most important to you.
