The Princess Cut is one of the most popular diamond cuts second only to the round brilliant cut. The choice of a Princess Cut Diamond Engagement Ring offers a stunning combination of classic sparkle with stylish angles that will undoubtedly appeal to the woman looking for a timeless look with a modern twist. 

ThPrincess Cut was designed to gain maximum brilliance from the diamond. It is widely held that the Princess Cut is unrivalled among other square cuts in terms of sparkle and much of its popularity has been achieved by the combining the brilliance of a round cut with the clean angles of a square shape and sharp, uncut corners.   

What is a Princess Cut Diamond?  

Princess Cut is the square version of the brilliant round cut diamond and displays a flat square or rectangular face, with an inverted pyramid profile. The Princess Cut is usually comprised of either 57 or 76 facets with a typical ratio of 1.0 to 1.05. The pyramidal shape of a Princess Cut diamond with four bevelled sides creates more light dispersion than any other square shaped diamond cut and its faceting style is unique and completely different from that of a round brilliant making it a highly popular choice as an engagement ring. Princess Cut diamonds also give the always-pleasing illusion of being of greater size due to their diameter being 15% larger than round diamonds of the same weight. 

The Princess Cut offers a more distinctive alternative to the more popular round brilliant cut and a Princess Cut diamond with the same width as the diameter of a round brilliant will weigh more. This is due to the fact that it has four corners which would otherwise have been cut off and rounded to form a round brilliant.  

What shapes are Princess Cut Diamond Engagement Ringavailable in? 

One of the unique qualities of the Princess Cut is the shape variations which can be achieved that other cuts simply cannot accommodate 

Princess Cut diamond can be given either a square or rectangular crown. Length-to-width ratios between 1.10 and 1.20 will give the impression of a diamond that appears more rectangular to the human eye, and between 1 and 1.05 appearing square in shapeThe choice of the shape of the best Princess Cut Diamond Engagement Ring is of course down to personal preference and style. Many women prefer the modern uniformity of a square Princess Cut diamond while others favour the uniqueness of a rectangular shape. Of note is that the square shapes do command premium being the more expensive variant of this  

The Princess Cut is patented and may also be referred to as a Square Modified Brilliant on a GIA laboratory certificate or a Rectangular Modified Brilliant if it has a ratio greater than 1.05. 

The number of chevrons can affect the overall outlook of a Princess Cut Diamond Engagement Ring. This can usually be determined by the wire diagram that is plotted in diamond grading reports. By adding more chevrons on the pavilion side of the diamond the individual facets of the diamond will now be broken down into smaller facets.  This results in the giving a Princess Cut diamond the look of crushed ice. Similarly when a Princess Cut diamond has fewer chevrons it then tends to give the diamond a chunkier look due to the broader facets. 

Due to the extra facets and ability to disperse more light through the stone within a Princess Cut diamondthis can serve to hide inclusions more efficiently which has the advantage of making it the most brilliant of all rectangular and square shaped gemstones.  

History of Princess Cut Diamonds  

The Princess Cut is a relatively new cut comparative to the round brilliant or cushion cuts. The Princess Cut originated in connection with another cut of diamond known as the ‘Profile’ cut which was designed in 1961 by London cutter Arpad Nagy. This name was also later used and made popular by Ygal Perlman, Betzalel Ambar, and Israel Itzkowitz in Israel, who in 1979 created the Princess Cut (or Square Modified Brilliant) as it is now known today.  

Other diamond cuts which are said to be precursors of the Princess Cut include the Barion’ which was created in 1971 by South African cutter Basil Watermeyer and is a square cut with rounded corners. similar cut but with only 49 facets referred to as the Quadrillion, was created by Perlman, Ambar and Itzkowitz and initially distributed by Ambar Diamonds in Los Angeles. Optical research undertaken in the 1980s saw the creation of the modern Princess Cut which is now recognised as a square stone of either 57 or 76 facets arranged similarly to those of a round brilliant cut diamond. Princess Cut Diamond Engagement Rings have very quickly gained popularity as an eye-catching alternative to traditional round diamonds, further supported by the suitability of this cut of diamond for almost any style of ring. 

Famous Celebrities wearing Princess Cut Diamonds Engagement Rings 

Princess Cut Diamond Engagement Rings are universally popular and many famous celebrities have chosen this cut of diamond for their engagement. These include actress Sherri Shepherd who starred in ‘The View’ and chose a stunning three-carat Princess Cut Diamond Engagement Ring, with a classic French-set diamond band when she married TV writer Lamar Sally in 2011. 

NFL player Hank Baskett proposed to reality star Kendra Wilkinson with a 2.25-carat Princess Cut Diamond Engagement Ring. The ring was valued at over $50,000 and was stunningly beautiful with a triple split-shank adding a vintage element to the centre stone’s square shape. 

Actress Jaime Pressly who starred in the hit TV sitcom ‘My Name is Earl’ accepted a proposal of marriage from entertainment lawyer Simran Singh when he presented her with an exquisite three-stone halo engagement ring with a Princess Cut centre stone. 

Are Princess Cut Diamonds Affordable?   

Princess Cut diamonds are one of the more economical of the diamond cuts in terms of minimised waste through the cutting procedure. For example, a round brilliant cut will generally yield approximately 40% which is equivalent to a one carat piece of rough diamond yielding a 0.40ct polished round diamond. In comparison a Princess Cut will yield in the 80%-90% range.  In effect two Princess Cut diamonds can be achieved from a single octahedron of a rough diamond which can therefore be reflected in a more affordable price tag. 

Choosing a Princess Cut Diamond Engagement Ring 

When choosing Princess Cut Diamond Engagement Ring one of the most important factors is to look for a certified Ideal cut which will ensure that the diamond that you have chosen is likely to be more fiery and sparkly than a less valuable stone.
