Princess cut diamonds really are royalty in the diamond world. Princess diamonds, which are one of the square cut diamonds, are the second most popular shape behind round diamonds. And, like the stones that rank slightly above them, princess cut stones are brilliant cut. Princess cuts have a square (sometimes rectangular) shape with pointed corners and up to 76 small facets. On a GIA report, you’ll see it called a square modified brilliant. But while these stones, which originated in the United States, have a gorgeous sparkle and daring corners, there’s a lot more to love about these square shaped diamonds — like the fact that their faceting reduces the visibility of flaws, or inclusions, in the diamond. To learn more about princess cut history, origin and popularity.

The princess cut diamond accounts for a whopping 30% of engagement rings, and shows no sign of letting go of its rank as the second most popular diamond choice. Maybe that’s because princess cut diamonds have such a classic look. When turned upside down they resemble pyramids, and their four sharp corners offer a subtle edge to the femininity of their sparkle. Whatever it is, it’s made this cut a popular choice for far more than princess cut diamond engagement rings. You can find the stunning stones on everything from necklaces to earrings, bracelets to ring-hand rings.

When the princess cut started and how it got its name

How long has this gorgeous cut been around? Well, there’s some confusion there. Many believe the history of the princess cut dates back to the 1970s when a new shape, the Barion Cut, was introduced by Basil Watermeyer. This particular cut was actually more a combination of the emerald cut and the marquise cut. Princess diamonds actually date back to 1961 when a diamond cutter who was based in London, Arpad Nagy, created what was known then as a profile cut. That same cut is now known as the princess cut. After a few years, Betzalel Ambar, Ygal Perlman, and Israel Itzkowitz popularized the new name, which is why we all known them now as “princess cut

Princess diamond popularity

Sure, we can tell you that the princess diamond is the second most purchased stone shape. (It is.) And that it even beats out its curvier cousin, the cushion cut. (It does.) But you probably don’t need these stats. The bold lines and understated drama of the princess cut probably speaks for itself. Many brides-to-be love that this stone shape combines the femininity of diamonds (all that sparkle and flash) with an architectural edge thanks to those sharp corners. They’re definite attention grabbers. And if seeing the stone wasn’t enough to convince you, maybe this stone’s fan club will. Here are just some of the celebrity engagement rings featuring princess cut diamonds:

  • Emily Ratajkowski couldn’t decide, apparently, because her unique engagement ring features a princess cut and pear shaped diamond on a gold band
  • Cameron Diaz shows off her princess diamond solitaire engagement ring that’s bezel set with a wide gold band free of accent diamonds
  • Jaime Pressly’s stunner is a 3 stone princess cut diamond ring with diamond halos around each of the brilliant stones
  • Carrie Ann Inaba said yes to her now-ex on live TV when he proposed with a 2.5-carat princess cut solitaire featuring a D color stone
  • Sherri Shepherd must love this diamond shape since her ring appears to not only have the princess at the center but also a channel set princess cut band
  • Kendra Wilkinson accepted a princess diamond engagement ring from NFL player Hank Baskett that features three bands and split shank design
  • Snooki of Jersey Shore fame said yes to a sizeable princess cut solitaire engagement ring set in a pave band featuring large stones
  • Star Jones’ ring from Al Reynolds, who she divorced in 2008, was a 7-carat princess cut stunner set with baguette stones on either side

Princess cut diamond pricing

Princess cut diamonds are very efficient diamonds for manufacturers, but what does that mean for you? They use a very large percentage of the rough diamond (approximately 60% – 70%), so very little of the precious rough material is wasted. Wasted material drives up the cost, so expect to pay less for a princess cut diamond than a round brilliant of the same carat weight. But keep in mind, this is a very popular cut. For that reason, you’re going to see higher prices with the princess diamonds than with other fancy shaped diamonds, such as the radiant cut or pear shaped diamond.

But, as with all diamonds, the price of your particular princess is going to come to down to how it’s evaluated according to the 4 Cs of diamonds. Cut is especially important as it impacts the brilliance, or sparkle, of your stone. A less well cut diamond will appear more dull, while excellent cut diamonds should retain their dazzling beauty. For that reason, you should look for a stone with an excellent cut, polish, and symmetry. Choosing a princess diamond with these characteristics can be pricey, but we have expert gemologists on staff to help you figure out how to maximize your budget and get the best stone possible. They’ll help you perform an in-depth diamond search to make sure you’re getting a stone that will turn heads without breaking the bank. You will have to decide something based on personal taste, though: the length to width ratio. This determines whether your princess will be a square diamond or rectangular. (More on this later.)

Keep in mind, though, that princess cuts carry more of their weight in their center or belly. That means they’re deeper stones than round brilliants and will look smaller at the same carat weight. That’s because their weight, instead of spreading to their sides like the round, spreads downward. If the size of your stone is a priority, simply tell your gemologist. They can keep this in mind while hunting for your perfect diamond.

Princess diamond guide: Understanding depth and length to width ratio

Princess cuts can be either square or rectangular. The ideal ratio, from length to width, of a square princess cut is 1.00 to 1.04. The ideal ratio of a rectangular princess cut is 1.07 to 1.15. Below are the proportion ranges for princess cut diamonds and their respective cut grades. When shopping at With Clarity, you’ll just need to know what shape you prefer. An expert gemologist can help you with finding the right ratio as long as you know what look you’re going for with your princess cut diamond ring.

Princess cut diamond engagement ring styles

Although, as we mentioned, princess cut diamonds are popular for other jewelry, we think they really shine in engagement ring settings. The daring corners of this shape make the stone perfect for a princess cut solitaire, but there are many more options. People sometimes debate a princess cut vs round when they’re shopping, and dislike how princess cut diamonds look smaller face-up. But we think there’s an easy and elegant solution. Princess cut halo engagement rings are a gorgeous way to make your center stone look larger. And since princess diamonds cost between 25% and 40% less than their round-cut counterparts, it can also be a stylish way to save money.

Ways to personalize your princess cut diamond ring

That’s probably why you’ll see a lot of princess cut halo diamond engagement rings once you start looking. If you’re going for something a little more unique, don’t worry. This diamond shape is versatile. It’s just as gorgeous taking center stage in a princess cut split shank engagement ring as it is in a square engagement ring with a halo. (Not all halos look the same, by the way.) And metals can make a big difference on your ring. A princess cut platinum engagement ring or a princess cut white gold diamond ring is a classic choice, but you can play up the romance by choosing a princess cut ring, or lend your look a vintage vibe by opting for a princess cut yellow gold engagement ring. And that’s before you even consider style elements like milgrain and filigree.

So even if you love the classic style of this cut, don’t feel boxed in by choosing a princess cut loose diamond. You can easily turn it into an engagement ring as stunning and unique as you are (or as the special someone you’re shopping for).

From experience, princess diamonds require higher depth percentages between 69-76% in order for it to have excellent light return properties. The table size of the princess diamond should not be too large (best range: 63-69%) as it affects fire and colored light dispersion properties.

Length to Width Ratio – Keeping It Square

The princess diamond is traditionally a square cut made of 4 equal sides. In my opinion, the ideal length-to-width ratio should be within the range if 1:1 to 1:1.02. Anything beyond a 1:1.05 would cause the diamond to look “off-square” to the eye.

Here’s a reference diagram that compares the outlines of different l/w ratios.

Most people prefer a squarish look instead of a slightly rectangular appearance. However, if you prefer a slightly rectangularish princess cut, that’s perfectly fine as well and it is what you like most that matter.

How Much Does a Princess Cut Diamond Cost?

Compared to round diamonds, the prices of princess cut diamonds are generally 25-35% lower because of the higher yield from the rough diamond cutting. This is due to the pyramidal shape of the princess diamond which results in minimal weight loss from an octahedral rough stone during polishing.

Out of all the different fancy shape diamonds, princess cuts are the cheapest per carat and this means you can get a bigger bang for your buck. Below, I’ve compiled a price comparison table using 1ct princess diamonds with different color and clarity ratings.

Price chart comparison of GIA certified 1ct princess shape diamonds.

From the table above, you can see that the price of a 1 carat princess shaped diamond can range anywhere between $2,500 to $8,000. This price variation is highly dependent on rarity factors like color and clarity.

Here, I want to highlight a common mistake that beginners make when they assume that a D/IF diamond will have better sparkle and brilliance compared to a lower color/clarity diamond.

In fact, if you chose a well cut G/VS2 princess diamond at nearly half the price of a D/IF diamond, you won’t be able to see any visual differences in the face up view between these 2 diamonds.

So, if you are a practical person and don’t need the symbolic IF clarity rating, then choosing a near colorless and eyeclean diamond will help you save a lot of money!

When it comes to buying diamond jewelry on a budget, the princess cut is a good choice for a balance of beauty and cost. This is because the brilliance and fire exhibited by a well-cut princess can help mask inclusions and hide body color.

As a result, you can go low on color and clarity grades without seeing any differences to the unaided eye. For people who are looking to get a cool, icy white appearance in their diamond ring, I would recommend a G or higher rating.

Here, I do want to point out that the choice of color is entirely subjective and up to personal preferences. If you are buying a yellow gold setting or prefer a warm looking diamond appearance, it is perfectly fine to buy a J or K color diamond. Plus, you get to save money too!

What Are the Best Clarity Grades for Princess Cut Diamonds?

Well cut princess diamonds display good scintillation and brilliance that can help cover up flaws in the diamond. Now, I’m a practical person and I don’t see a need to pay the premium for a high clarity grade that doesn’t provide any visual benefits to the naked eyes.

I recommend buying diamonds in the SI1 or VS2 clarity range to save money as long as the diamond is eyeclean (inclusions cannot be seen with naked eyes). The caveat here is that you need to purchase from a retailer that provides photos or videos of the actual diamond to help you assess eyecleanliness.

Check out these 2 examples of SI1 diamonds below and click on the images to interact with the video listings. Are you able to quickly tell which is eyeclean and which isn’t?

The best method of determining eye cleanliness would be through the use of high-resolution videos or photographs. James Allen and White Flash are 2 vendors that excel in this aspect and they come highly recommended.

3 Things You Need To Beware Of When Selecting Princess Cut Diamonds

#1 – The 4 Pointed Corners Are Vulnerable Areas

When setting a diamond, the 4 corners of a princess cut diamond are prone to chipping due to the lower mechanical strength at the points. In general, I would avoid princess cuts with severe inclusions located near the corners because they can create weak points in the crystalline structure and cause durability issues…

 This I1 princess cut has a crystal inclusion that poses a significant danger for durability.


#2 – Beware of Weight Retention Tricks Employed by Cutters

In the profit-driven industry of diamond cutting, the majority of polished diamonds are cut to preserve the maximum weight from the rough. This is usually done at the expense of cut quality and better sparkle.

In princess cut diamonds, the tell-tale signs of diamonds cut with weight retention techniques are table percentages near or higher than 80% and very thick – extremely thick girdles.

83% table size

This hideous looking diamond has uneven-sides and an enormous table size of 83%.

The problem I personally have with such diamonds is that their optical performance had been compromised for higher carat weight. For example, having a table size that is too large will result in a significant reduction of fire.

Excessively thick girdles are also something I would avoid because they lock in carat weight at the girdle area which can’t be seen once the diamond is mounted. This means that you get a significantly smaller looking diamond despite paying more for carat weight!

#3 – Poor Outlines And Shape Appeal Issues You Should Avoid

Did you know that princesses can come in all sorts of shapes and outlines?

Sadly, the market is flooded with a lot of badly cut diamonds with poor visual appeal and light performance. Below are some of “bad” examples of shapes and outlines that princess cuts can come in.

shape issues and l/w ratios

One of the most common mistakes people make when buying fancy cuts is to buy sight unseen or based solely on a grading report.

This is because the grading report alone will never tell you how the diamond looks like in real life. To avoid such problems, I highly recommend that you work with vendors that offer visualization technologies so that you know what you are getting.

Here are the full details of the ring I put together by combining the loose diamond and ring setting design:
