![]() The Barion Cut has since faded into obscurity but it is generally considered to be the forerunner of the Princess Cut we know today. In 1971, Basil Watermeyer of Johannesburg introduced the ‘Barion’ Cut, a square cut diamond with 4-fold mirror-image symmetry, clipped corners, and a total of 81 facets. Over the years, the term Princess Cut has been used in connection with other styles of cut, such as the Profile Cut designed by Arpad Nagy (London, 1961). Compared to the French Cut, the Princess Cut has more facets giving it much more sparkle. It emerged in the 1960s and has its basis in the 15th Century French Cut, which was used to create typically square or rectangular stones with a ‘cross’ pattern clearly visible in the crown. The Princess Cut is a generic cut, meaning it hasn't been patented by or attributed to one designer. Refer to the table below to see how we grade Princess Cut diamonds. These take into account factors such as table and depth percentage, polish and symmetry, and length-to-width ratio. We’ve developed our own criteria to provide consistent cut grading for all the Princess Cut diamonds we offer. Instead, it’s down to individual retailers to evaluate the quality of the cut for this shape. If choosing a Princess Cut, bear in mind the sharp corners are a point of weakness and can be easily chipped so ensure they’re protected by the setting.Ĭurrently, there aren't any universally accepted standards for grading the cut of Princess Cut diamonds so certifying laboratories don’t do it. Unlike other square styles (Emerald and Radiant) the Princess Cut does not have clipped corners. Despite this, a Princess Cut diamond retains approximately 80% of the original rough diamond crystal compared to the Round Brilliant’s 50%, so Princess Cut diamonds are usually better value weight for weight. Due to its design, the Princess Cut requires more of the carat weight to be directed towards the base of the stone to maximize brilliance, which means a Princess Cut stone will appear smaller than a Round Brilliant of the same carat weight. ![]()
