If you're in the market for a diamond engagement ring, you've probably heard of both princess-cut and Asscher-cut diamonds. But what's the difference between princess cut vs. Asscher cut stones? Here's a quick rundown of the key differences between princess-cut and Asscher-cut diamonds.


Princess cut diamonds have a distinctive shape and a lot of sparkle. The princess cut has a square outline but occasionally has a somewhat rectangular contour depending on the original diamond being cut and the buyer's preferences. These diamonds contain 58 facets in positions close to those of round-cut diamonds.


The most noticeable distinction between Asscher and emerald cuts is that Asscher cuts are square rather than rectangle. This cut produces a brilliance unmatched by any other diamond shape thanks to its broad step facets and tall crown. In fact, diamond specialists frequently compare the radiance and brightness of an Asscher cut diamond to a long corridor lined with mirrors.

Although most people associate the Asscher cut with a square shape, it features four chopped corners, giving it a slightly octagonal appearance. Contrary to a real octagon, these chopped corners are not evident until you place the diamond into a four-prong setting.


The princess and Asscher cuts have similar profiles but are made differently, impacting how brilliant and colorless they appear.

Let’s take a look at the key ways in which these two diamond cuts differ:

1. CUT

One difference between Asscher and princess cut is the cut.. While the two cuts appear to be similar, their facets are fundamentally different in both shapes and arrangements.

The facets of the Asscher cut are parallel to the girdle and/or to one another because it is a step cut.

In contrast, the facets of the princess cut are not formed and placed in a linear pattern like those of Asscher diamonds, and it is frequently referred to as a "modified-brilliant cut."


Because of their exceptional brilliance, princess cut diamonds have a lot of white light reflection, or "sparkle." Due to the way they are crafted from the rough stone, princess cuts have some of the highest brightness of any diamond shape.

Asscher-cut diamonds display a soft sparkle because their step-cut facets refract light differently than a brilliant-cut diamond.

Asscher-cut diamonds produce the colors we call fire by reflecting and flashing light. They simply aren't that shiny, though. This is particularly true when you contrast them with a round, brilliant, oval, cushion-cut, or even triangle-cut diamond.

This low shine is because of the step-cut style of Asscher diamonds. Their facets are a series of parallel, mainly rectangular structures. When compared to the diagonal faceting of brilliant cuts, step-cut diamonds appear less brilliant and more structured.

Some people might think the Asscher cut diamonds are understated and sophisticated. A well-cut Asscher diamond's dazzling, vivid light flashes give off a mesmerizing "hall of mirrors" effect.

As a result, princess-cut diamonds sparkle and have greater brightness than Asscher-cut diamonds.


The next difference between Asscher and princess cut is color.

Asscher-cut diamonds exhibit more color; in comparison, princess cuts exhibit less color due to their brilliance, reducing the visibility of yellow tints. As a result, you can choose a princess-cut diamond with a color grade as low as H or I without noticing any obvious yellowish undertones.

In contrast, Asscher cuts require extra caution because any color in such stones tends to stand out more; stick to H color or above with Asscher cut diamonds.

When Asscher cut diamonds are larger than 1.5–2.0 carats, the step facets make it easier to perceive color. Many diamond authorities advise limiting Asscher diamonds to an I hue. This grade is the ideal middle ground for this cut since it will give you a gorgeous color without breaking the bank.


Since the stone's table is flat and provides a clear view into the stone's interior, inclusions are clearly visible to the naked eye. Because of this, it is recommended that you consider purchasing a stone with a clarity grade of at least VS2. Setting the clarity scale a little bit higher for step cuts like the Asscher is vital even though you may easily go lower clarity grades for other cuts.

A princess-cut is more tolerant of inclusions than other square cuts (such as Asscher and emerald) due to its brilliance, especially when seen with the naked eye.

Generally speaking, these stones can have clarity as low as SI1 and still not show visible defects. However, you should watch out for inclusions in the corners of a princess cut. Inclusions in the corner areas of this stone cut make it weaker and more prone to break.


Now that you know the differences between princess cut vs. Asscher cut, you can make a more informed choice when picking the right cut for your needs.

If you are looking for a diamond with maximum brilliance and sparkle, go for a princess cut. Asscher-cut stones, on the other hand, have a vintage feel to them and will be a good choice if you are looking for something unique.

Of course, the final decision is up to you – pick the cut that you like best!
