There are several types of standard diamond shapes that are available from most retailers, including radiant cut diamonds. Radiant cut diamonds are one of these shapes. Each shape has its own unique characteristics as well as potential problems to be aware of when making a selection, and the radiant cut is no different in this respect. In order to make the most informed choice possible, and thus get the best value for your money, it’s a good idea to familiarize yourself with the details behind radiant cut diamonds.
What are radiant cut diamonds?
Compared to the other popular diamond cuts, the radiant cut had a relatively recent emergence. The radiant cut is a mixed cut, meaning that it has elements of both a step cut (square or rectangular cuts with long facets, like the Asscher cut and the emerald cut) and a round cut. The radiant cut has rounded and comparatively short facets, making it closer to a round cut in this regard.
This, in turn, gives the radiant cut the same sort of brilliance and shine that makes the round brilliant cut so popular. Its overall shape, ranges from square to rectangular, as is the case with step cuts, and this makes the radiant cut suitable for settings that wouldn’t be possible for a round cut.
The ideal radiant cut has 70 small facets. When viewed from the top, a high quality radiant cut will have a diagonal cross pattern, which distinguishes the radiant from most other cuts. There are many slight variations on the radiant cut also in existence, but the standard radiant is generally considered the most versatile. Most radiant cut diamonds have a slightly rectangular shape, with a length to width ratio as high as 1.2, but they can also have sides of equal length.
What makes radiant cut diamonds special?
Like other mixed cuts including the popular princess cut, radiant cut diamonds effectively combine the angular elegance of step cuts with the sparkle and fiery appearance of the round brilliant. The most obvious difference between the radiant cut and the princess cut is that the radiant cut has cropped corners, which again is more akin to step cuts like the emerald cut.
Radiant cut diamonds can be used in a variety of settings. They have enough beauty to be used effectively as solitaires, and they are also often set with accent stones.
What should I look for in radiant cut diamonds?
Although the radiant cut does have some features in common with the emerald and Asscher cuts, the radiant’s short facets mean that it isn’t as vulnerable to some of the clarity-related issues that can affect the step cuts. Also, the radiant cut doesn’t suffer from the problem of color accumulation in the corners that plagues some of the other specialized non-round cuts.
Instead, when assessing radiant cut diamonds, you can use essentially the same parameters that you would apply to a regular round brilliant diamond. This means that, in order to get the best possible value for radiant cut diamonds, you should consider using the following certification grades as a template: a cut grade of Good; a clarity grade of SI1 or SI2; a color grade of G (although in some cases diamonds with a color grade as low as I will still not show any coloration to the naked eye); and a carat weight in the range of 1.
