Diamond Dictionary: Radiant Cut DiamondsIf you prefer a rectangular shaped diamond but want the brilliance of a round cut, the Radiant cut diamond might be a great selection for you. Radiant cut diamonds combine the classic shape of the Emerald cut with the life and fire of a Round Brilliant. They tend to lengthen the sightline on a woman’s finger, thus resulting in a classic, elegant and somewhat slimming look. Radiant cuts are described by the Gemological Institute of America (GIA) as ‘Cut Cornered Rectangular Modified Brilliant’ diamonds.

The Signature Characteristics of a Radiant Cut Diamond

The signature characteristics of Radiant cut diamonds are the straight edges, 45 degree cut corners and flat table. There is no ‘ideal’ depth and table parameter for any fancy cut diamonds because these percentages vary based on the length, width and depth measurements of each unique stone.

When set in a piece of jewelry, a Radiant cut diamond may appear similar to a Cushion cut diamond with the difference often only be noted under close examination with a jewelers loupe. Selecting a square or rectangular Radiant cut diamond is a personal choice and when cut beautifully, both have equal fire and brilliance. At Ascot, we typically care for more elongated radiants that have around a 1.30:1.00 ratio. This tends to result in the maximum brilliance possible when cut by a superior diamond cutter.

A radiant cut can add a unique twist to a classic diamond solitaire engagement ring, or it can be accented with other diamonds for a 3-stone-style design.

4 Things to Consider When Purchasing a Radiant Cut Diamond

When determining if a Radiant cut diamond is the right shape for you, consider the following:

  1. Properly proportioned radiant cuts maximize carat weight by using more of the gem in visible ways, rather than beneath the surface of the stone or under prongs in the corners.
  2. A Radiant diamond’s additional facets can help conceal diamond flaws (inclusions) to make the stone more ‘eye clean’ in terms of clarity.
  3. Because they don’t have the delicate corners, radiant-cut diamonds are more durable and may be more suitable for an active lifestyle than other shapes like a Princess, Marquise or Pear shape diamond.
  4. Colored Radiant cut diamonds are especially popular and stunning because they show extraordinary depth of color evenly throughout the stone.

If you’re looking for an alternative to a Cushion or Princess cut diamond, a Radiant cut is a wonderful choice. To see some of the most exquisitely cut Radiant cuts in the world visit Ascot, where we care about the clients we serve and every diamond we sell.
