Table of Contents

When it comes to choosing diamond engagement ring styles, it’s good to narrow down your preferences. But, if you are big on the sparkle factor, then your choices might lead you to these two: the round cut vs princess cut.


Both known for their beauty and brilliance, choosing one wouldn’t be in any way inferior because they are both stunning in their own ways.


Having said that, let’s take a look at princess cut versus round cut diamond and find out which fits your style more.

Round Cut vs Princess Cut Shape Differences

The main difference between these two cuts is their physical forms. While both have 58 facets(flat surfaces), their shapes are visibly distinct from each other.

The princess cut features a square tablet with beveled sides and looks like an inverted pyramid. The shape sometimes looks a bit rectangular depending on the raw diamond’s shape and the buyer’s preference.

Created by London-based diamond cutter Arpad Nagy in 1961, it is considered a more modern cut compared to the classic round which has been around since 1919 when Marcel Tolkowsky created it.

The round cut has a circular top and its small facets are designed to take, refract, and reflect maximum amount of light.


The round and princess cuts are your top two choices when it comes to light performance. This refers to the way they emit white light and flashes of it when viewed from top view and from any direction. Both have 58 facets that allow them to respond to light in a way that shows off their intense force, brilliance, and scintillation.

But why are round cut diamonds considered the most brilliant of all? Because of its cut that combines mathematics and artistry to come up with the optimum placement of facets.

The round cut maximizes how light moves when it hits the diamond. It also reflects over 90% of light while the princess cut reflects 70%. This makes the round cut more brilliant than the princess cut and every other diamond cut out there.


This actually refers to the diamond’s absence of color or colorlessness. The more colorless a diamond is, the more precious and valuable it is. Lower grade diamonds would have some light yellow or brown tinge giving them less ability to reflect light, hence, relatively less brilliance.

Unless you prefer colored diamonds like blue and pink which are actually more rare and expensive, you’d want your diamond to be as near to a colorless state as possible. The round cut reflects light better than the princess cut — this gives it more ability to hide color and show off its undimmed sparkle.


This refers to the absence of flaws in the diamond like inclusions or the internal flaws, and blemishes or external flaws. Like color, the round cut also has more ability to hide flaws making it a good choice if you want a pristine looking diamond.

While flaws are unavoidable in natural, mined diamonds, hiding them gives the stone a more resplendent look. High clarity means high price.


The princess cut’s wider, square (sometimes subtly rectangular) table or top surface. This gives it an illusion of looking bigger than a round cut diamond of the same carat weight.

So if you want a large looking diamond that also scores high on the sparkle meter, the princess cut is the one for you.


The round cut is the most expensive diamond out there because it takes a lot of skills to craft it and it also has the most raw diamond wastage during the cutting process. And because of its brilliance, it has the highest market demand that contributes to driving its value and price up.  

All That Sparkles is Not The Same

If you’re still undecided in this round vs princess cut diamond option, here are our tips.  Choose the round diamond if you want a classic, high grade looking, uber brilliant piece that screams luxury and budget is not an issue.

But if you want to stay within your budget, enjoy a good amount of brilliance, and want a large looking diamond — the princess cut is your best bet.

It also has a more modern and unique aesthetic that works well for those who want their rings to stand out from the sea of round sparklers out there.
