The Princess Cut Diamond
Gaining in popularity in recent years as a more distinct alternative to the more popular Round Brilliant cut, the face of the Princess Cut diamond is square or rectangular in shape. Created in the 1960s, the Princess Cut is relatively new form of diamond cut. When looking at the cut of the diamond of the profile, or side-on, the shape is similar to that of an inverted pyramid with four beveled sides.
Grading Princess Cut Diamonds
Although there are institutions that do give a Cut grade to Princess shaped diamonds, world-renowned Gemological Institute of America (GIA) does not. Citing not enough industry consensus or empirical data to specify cut standards. As a result, GIA will only grade Polish and Symmetry on a Princess Cut diamond.
In terms of cut parameters, a depth of 65% to 75% of the diamond width is desirable. You should also seek to find square Princess Cut diamonds which have a length/width ratio in the range of 1.00 - 1.05. The table should be around 75% of the width of the diamond.
A Princess Cut diamond of equal carat weight to that of a Round Brilliant will usually be slightly cheaper. This is because compared to a Round Brilliant's 50%, a Princess Cut diamond retains about 80% of the rough diamond. Simply, this means that with a 1ct rough diamond, creating a Round Brilliant will leave approximately 0.5ct of diamond. Cutting that same rough diamond in a Princess Cut will leave 0.8ct of diamond, quite a difference!
