Princess cut diamonds and radiant cut diamonds are kind of like fraternal twins. Very similar, but when you look closely, a little bit different. Both of these shapes are widely available with a square outline, however you can find gorgeous elongated versions of each as well, if you prefer a more rectangular shape. One of the biggest differences is that princess cuts have sharp pointed corners while radiant cuts have cropped corners similar to an emerald or Asscher cut diamond.

Absolutely! A relative newcomer to the diamond market, princess cuts were conceived in the 1960s and perfected in 1980. They are second in popularity only to the round brilliant cut, and they're basically the square version of the same. Keep an eye out because it won’t say “princess cut” on a diamond grading certificate, instead look for “square (or rectangular) modified brilliant”.

Princess cut diamonds are cut with brilliant radiating facets, just like a round diamond. A well cut one is exceptionally sparkly, but princess cuts (and other fancy diamond shapes) don't have an industry standard cut grade like round diamonds do. Look for a depth percentage between 68%-75%, along with a table percentage in the same 68%-75% range for a nicely balanced and brilliant diamond. And like other shapes, look for excellent polish and symmetry for a well finished stone with even light distribution.

Shaped like an inverted pyramid, princess cut diamonds are a unique shape that stands out from others with its clean lines and sharp pointed corners. This shape offers a ton of sparkle, looks quite modern, and costs around 20-40 percent less than round diamonds of the same characteristics.

Princess cut diamonds suit many modern engagement ring designs. The most important factor in setting a princess cut is to ensure that the diamond's delicate pointed corners are protected, either with prongs or a bezel wall. If you want your stone to really stand out, a princess cut solitaire is beautiful. The Frank Darling signature half bezel princess cut ring is a unique modern alternative.
