princess cut diamonds 3d rendering

Beauty In a Squarish Form

Most consumers love the standard hearts and arrows (round) diamond because of its unparalleled brilliance and sparkle. However, with growing consumer needs and diversifying tastes, variations to the round brilliant cut (each with their own unique properties) had seen a recent resurgence in demand.

The princess cut is currently the 2nd most popular shape after the round diamond. It was first introduced to the world in the 1960’s by a man from London named Arpad Nagy. Back then, the princess cut was derived as a variation of another cutting style called the “profile cut”.

A. Nagy wanted to create a cut that could make efficient use of rough stone with less wastage and one that could emulate the brilliance and fire of a brilliant cutting style. Over the course of a few years, leading cutters had poured in huge efforts in optical research to perfect the design and evolved it into what it is known as today as the square modified brilliant.

The Princess Cut’s Route to Popularity

With a market that is over-saturated with rounds, the princess cut offers a unique looking option to women looking for an alternative fashion statement. The princess diamond is technically a mixed cut whereby both step and brilliant cutting styles are incorporated.

While the princess cut has light performance that can be comparable to the round brilliant, it costs significantly less! Due to its better yield from the rough stone, it would please you to know that the price-per-carat weight of a princess cut is the lowest amongst all the shapes.

Can you see the “cross” smack right in the middle?

What makes a princess cut truly unique is that a reflection that looks like a cross is observed when light passes through the diamond. Coupled with 4 pointed corners, superior brilliance and scintillation patterns, these reasons contribute to the appeal that women have for the shape.

Getting Started in Selecting Your Stone

 
   
 

Being a relatively new cutting style, most labs (except AGS) do not issue a cut grade for the princess cut. At the point of writing this article in 2013, ongoing research studies and debate are still being carried out by labs about the introduction of a cut grading system for them.

Due to its four-sided shape and variances in facet layouts, diamonds with similar specifications on a grading report will still look different in appearance. With the absence of an objective cut grade, this adds an element of difficulty in choosing a well cut diamond.

When selecting a princess cut diamond for optimum brilliance, you generally want to avoid stones that have a table % larger than the depth %. The majority of nice performing stones tend to have smaller tables in the 64-69% range. Also, my personal preference and advice is to stick with a minimum of G color and SI1 clarity.

Recommended Proportions for Princess Cut Diamonds

Excellent Very Good Good Fair/Poor
Table % 63% – 69% 57% – 75% 53% – 82% Outside Ranges
Depth % 69% – 76% 60% – 78% 58% – 80% Outside Ranges
Polish/Symmetry Excellent – Very Good Good Outside Ranges
Length to Width (Square) 1.00 – 1.02 1.00 – 1.04 1.00 – 1.05 Outside Ranges
Length to Width (Rectangle) 1.5 – 1.75 1.76 – 1.85 1.86 – 1.99 Outside Ranges
Girdle Thickness Thin – Slightly Thick V. Thin – Thick Outside Ranges
Culet Size None Very Small Small Outside Ranges

* Note: The proportions table should be used as a reference only. You should incorporate light performance data like ASET images to help you make a final decision. Never go below very thin for girdle thickness or you run the risk of chipping the diamond easily.

Length to Width Ratio – Keeping It Square

length to width ratio of princess cut diamonds

As much as possible, you should try to stay within the range of 1:1 or 1:1.05 for your length to width ratio. Anything that is higher than 1.05 will cause a diamond to look off-square to the eye.

    I’m looking for a 1.5 carat sized princes cut diamond engagement ring for an upcoming proposal. Do you know of any diamond importers with great wholesale pricing in the Ohio region?

    Also, can’t you teach me how to choose a princess cut diamond that does not have certifications? I have a local dealer here that sells both certified loose diamonds and those without. They are having a sale on those stones that do not have certifications. The prices on those look really tempting and I’m not sure whether any of those are ideal choices.

    Sorry for any bad English. It is not my native language.

    I think you are taking an extremely dangerous approach in your shopping process. First of all, “wholesale” pricing in the diamond industry don’t exist for consumers. It’s a marketing scam (just like the big banners that scream “princess cut rings sale”) used to draw in unsuspecting consumers with the false impression of preferential pricing.

    I would NEVER buy such a large sized diamond (1.5 carats) without proper grading reports to accompany them (i.e. GIA/AGS). Often times, they are misrepresented. I advice sticking with AGS ideal princess cut diamonds and you can find a couple of companies that deal with these beautiful stones here:

    I’m torn between the choice of round vs princess cut diamonds. My fiancee had given me the option of choosing one for myself with a budget of $8,000. I had seen a number of engagement rings in a local Jared store and it seems like princess cuts are cheaper by their carat weight.

    I compared a 1 carat round vs a 1 carat princess cut diamond in a solitaire setting and noticed that the round looks slightly bigger. Is this due to the depth of the stone? Obviously, I want the largest looking stone for the least amount of money. I can’t make up my mind and would like your advice on which is better: the princess or the round?

    It’s true that princess cuts tend to have deep depths. This makes them face up slightly smaller. However, because of the cutting style, polishing princesses tend to have better yields from the rough stones. This is why they are priced lower than a round diamond with similar carat weight. Choosing between a round and a princess is really up to personal preferences. If you are unsure, try to look at more stones and engagement rings in person. This will help you decide which shape your tastes are geared towards.
