The Lucere® cut diamond is essentially a modified square brilliant cut diamond. The underside of the diamond is faceted for maximum light return and displays greater brilliance than the standard princess cut diamond.

There are two types of Lucere diamonds. The American Lucere features a step-cut crown and a brilliant-cut pavilion. These diamonds are always square in shape.

The European Lucere diamond, fashioned after a radiant-cut diamond, has 20 more facets than the American version to maximize brilliance and scintillation - 16 of the additional facets are placed on the crown and four on the pavilion. The European Lucere diamond can be cut as a square or a rectangle.
