Hearts and Arrows Diamonds are precision cut variations of the traditional 57 faceted round brilliant cut. They are cut to “ideal proportions” with superior optical symmetry and a specific faceting pattern. When all these factors are in harmony the result is a repeatable, near perfect pattern of eight symmetrical arrows in the face up position and eight symmetrical hearts when viewed in the table down position.
As you research diamonds, you may have seen information about lab created diamonds versus naturally formed diamonds. Some people may refer to lab created diamonds as “fake diamonds”, imitations or simulants, but this is incorrect. Lab created diamonds share the same or similar chemical and physical properties as a natural diamond produced by the geological processes of Mother Nature. However, because of the contrasting conditions of natural and lab grown formation, lab grown diamonds display several features which allow them to be gemologically distinguished from natural diamonds. On the other hand, cubic zirconia and moissanite—which can look like diamonds—have very different chemical and physical properties and are known as simulant diamonds.
