The Radiant Cut diamond is the most modern shape of diamond, and is now in the top 5 of most popular diamond cuts used in engagement and wedding rings.

The Radiant Cut diamond rose to popularity in the 1980s largely due to its impressive brilliance and fire which is created by the 70 facets found within the diamond’s crown and pavilion. The brilliance exhibited by the Radiant Cut is second only to the Round Brilliant Cut which makes for a show stopping centerpiece in items diamond jewelry such as engagement rings. Despite the modern origin of the Radiant Cut, this diamond cut is classically elegant and looks perfect in either a contemporary or vintage setting, Let’s take a close look at Radiant Cut diamonds.



The Radiant Cut was designed in 1977 by Henry Grossbard a master diamond cutter who wanted to create a cut that would maximize a diamond’s brilliance. Grossbard combined the best features of the Round Brilliant Cut with the Emerald Cut to create what we now know as the Radiant Cut. This was a combination of the elongation of the Emerald Cut and the many facets of the Round Brilliant Cut which produced a diamond that was the very first to have a brilliant facet pattern on the pavilion as well as on the crown.

Radiant Cut diamonds are a hybrid of the Round Brilliant Cut and the Emerald Cut. They are perhaps best known for their emerald like rectangular shape, but can also be cut to resemble a more square shape which looks more like a Cushion Cut diamond. The most striking characteristic of Radiant Cut diamonds is the unrivaled magnificent sparkle created by the greater number of facets numbering 70.
The length to width ratio is an important factor in Radiant Cut diamonds as if they are too elongated the undesirable ‘bow tie effect’ can appear. However, this is not as common as in Pear, Marquise or Oval Cut diamonds.
The majority of rectangular Radiant Cut diamonds radiants are in the L/W range of 1.20 to 1.40, for square Radiant Cit diamonds ratios can range from 1.05 to 1.50.
The corners of Radiant Cut diamonds should always be clipped to a balanced size so that they don’t have the appearance of being the same size as the sides of the diamonds. However, if they are clipped to small the angle that they bring to the shape of the diamond will be lost by the prongs within the setting covering them.
