Differences You Need To Know Between A Princess Cut And An Asscher Cut Diamond

When choosing diamonds everything comes down to the 4Cs. It is a diamond’s cut, clarity, color, and carat weight that decides its price.

However, everything is not about technicalities with diamonds. Your preference and want for a specific shape of a diamond might dictate your choice. In such a situation it is a person’s aesthetic choice that takes precedence.

Apart from their quadrilateral shapes, there is little similarity between Princess Cuts and Asscher Cuts.

Although the Princess cut is more popular, the Asscher Cut is a collector’s piece, and in certain ways equally valuable if not more than a Princess Cut.

Let’s find out how

Basic Differences Between Princess Diamonds and Asscher Diamonds

Before we get technical details, it is always better to start with the basics.

What is a Princess Cut?

This cut is the second most popular cut of diamonds in the world and accounts for more than 30% of all engagement rings.

Princess cuts have a massive yield from the diamond rough. To give you an example, A Round brilliant’s yield will be around 40%, whereas a Princess cut’s yield is between 80-90% from a diamond rough.

This cut was made by Arpad Nagy in 1961. But the princess cut only experienced fame in the 1980s when Betazel Ambar and Israel Itzkowitz popularized this particular cut.

The term, ‘princess cut’ was given to a particular cut by Arpad Nagy called the profile cut. Owing to this, more square cuts were given this name like the quadrillion cut and the barion cut.

The evolution of the square-cut diamond into the square modified-brilliant cut in the 1960s was on account of advancements in the field of diamond cutting and also increased knowledge of light performance in diamonds.

What is an Asscher Cut?

An Asscher cut diamond is a square-shaped diamond, with layered facets and flattened edges.

A clear view of the facets right to the center of the stone is achieved due to the flat table. This alignment of the facets renders a beautiful ‘hall of mirrors’ illusion to the eye.

Produced by the Asscher family of Holland in 1902, the Asscher cut did not gain popularity till the 1920s making it a hallmark piece of the Art Deco era.

But, the popularity of this cut was short-lived and the abode of this particular cut became limited to vintage jewelry stores. It is only in 2002, that the Asscher diamond made a comeback. It is not one of the popular cuts of the 21st Century and is highly underrated.

Shape and Symmetry

A Princess Cut Diamond is a square-shaped diamond with sharp corners having 56-58 facets.

It is also referred to as a ‘square modified brilliant cut’.

The division of facets is generally, 21 on the crown, 4 on the girdle, and 33 on the pavilion. 25 facets is also a common occurrence in a princess cut diamond.

Princess cuts either have French or Bezel corners and have diamond-shaped facets extending from the table corners to the stone corners.

An Asscher Cut Diamond has 58 facets.

However, modern renditions, like the Royal Asscher cut have 78 facets resembling the original design.

Owing to the cut, the weight of the diamond is concentrated towards the center, rather than the edges.


The GIA does not grade the cut quality of fancy-shaped diamonds, making it difficult to accurately judge the cut quality of a princess cut or an Asscher Cut. The depth, table, and symmetry are very good indicators of the diamond’s cut quality.

Princess-Cut or Asscher Cut: Which One Is the Better Choice?

This question is very difficult to answer. Diamonds are luxury and personal items. One can view them from the perspective of a good investment.

However, in certain situations, the aesthetics of a particular shape is preferred over the 4Cs. For instance, heart-shaped diamonds lack the brilliance of a round brilliant cut but have a more pronounced sentimental value associated with them. Heart-shaped diamonds are considered the most romantic of all diamonds.

In the case of Asscher cuts, they have a vintage look associated with them, which would be preferred by those looking for a subtle diamond. In such situations, the lack of fire and brilliance might just make the cut. 

The most unique aspect about Asscher cut diamonds is that they are very rare. Princess cut diamonds account for almost 30% of all engagement rings. This makes them very common. Couples today are always looking for unique experiences and having a rare cut might be considered more memorable than a popular cut.

The same is true for Grey Diamonds, their rarity account for their popularity. Asscher Cuts are relatively cheaper than Princess Cuts and a good choice for an engagement ring.

Princess cuts on the other hand are the second most popular diamonds with amazing brilliance. There are no prizes for guessing why you would want to choose a Princess.

It is always better to consult an expert on the matter. Both the cuts are worth buying. Although Princess cuts are a popular choice, stumbling upon an excellently cut Asscher Diamond might just change your mind.
