Radiant Shape Diamonds

A diamond's shape is its outline when viewed from the top and is one of its most important defining characteristics. Found in square and near-square variations, the radiant cut diamond combines the brilliant faceting of a round cut with the elegant shape of the emerald cut. Due to its 70-facet design, a radiant cut diamond displays large amounts of fire and scintillation.

Diamond Shape

When selecting a certified diamond, shape is one of the most important factors to consider. The contours and outlines of a loose diamond have a significant impact on its appearance. At Brilliance, we offer the ten most popular shapes in our certified diamond search. Round diamonds have long been the most popular, although many modern consumers prefer alternative shapes, including emerald, princess, radiant, and asscher, among others. Each diamond shape has its own unique traits, aesthetic properties, and markings of quality.

Radiant Cut Diamonds

Relatively new to the jewelry industry, radiant cut diamonds were introduced a little more than 20 years ago. This unique shape is a stunning hybrid of a traditional round cut and an elegant emerald cut, resulting in a square, near-square, or rectangular orientation.

With an intricate 70-facet cut, radiant cut diamonds exude tremendous brilliance. Those who appreciate the fire of round diamonds and the sophistication of emerald cut or asscher cut diamonds will find the radiant cut to be highly desirable.

To achieve optimal symmetry and light performance in a loose diamond, the stone must be cut to specific depth and table percentages. The depth percentage of a diamond measures the ratio of the stone’s depth to the diamond’s total diameter. The table percentage is the ratio of the width of the diamond’s top facet in relation to the width of the entire stone. For radiant cut diamonds, the depth and table ranges below will yield different qualities of cut.

  • Depth Percentage
    • Ideal: 75% - 66%
    • Excellent: 76.5% - 64%
    • Very Good: 78% - 62%
    • Good: 84% - 56%
  • Table Percentage
    • Ideal: 75% - 66%
    • Excellent: 77% - 64%
    • Very Good: 79% - 62%
    • Good: 82% - 55%

Every diamond shape has a length-to-width ratio, which determines how a certified diamond will appear when viewed from above. When selecting a square shaped radiant, look for a length-to-width ratio between 1 and 1.05. For those who prefer a rectangular shaped radiant, choose a length-to-width ratio of 1.15 or greater.
