About Princess Diamonds

A princess cut diamond is traditionally a square diamond that offers excellent fire and brilliance. This fancy shape diamond is designed from the inverted pyramid of the rough diamond stone. 

How Many Facets Does A Princess Cut Diamond Have?

A princess cut diamond or square modified brilliant cut diamond usually has between 50 and 58 facets, depending on how the diamond is cut. Most of the facets are on the pavilion and crown, with a few on the girdle. Princess cuts also typically have two to four chevron patterns, which are cross patterns that can be seen when viewing the diamond from above. 

When a diamond has two chevron patterns, the diamond reflects bolder flashes of white and colored light. When a diamond has four chevron patterns, the diamond has more scintillation — resulting in smaller flashes of white and colored light that can be seen when the diamond moves. 

What Princess Cut Diamond Color Should I Choose?

When it comes to diamonds, the princess cut is renowned for its brilliance. This cut allows for a lot of white light to be emitted, which results in an impressive sparkle. This feature is particularly beneficial in minimizing the appearance of any yellow or brown tints that may be present in the diamond. However, it's important to note that princess cut diamonds tend to retain more color than round diamonds. Therefore, it's advisable to opt for a colorless range of D to F, or at the very least, H.

HOW DOES PAVILION DEPTH AFFECT A DIAMOND’S CUT?

Pavilion depth is measured from the bottom of the girdle to the culet. The pavilion depth that's too shallow or too deep will allow light to escape from the side or bottom of the stone. Light will be directed through the crown of a well-cut diamond.

The Princess Cut

The princess cut shape comes from a pointed shaped diamond rough. Focusing on maximizing the rough diamond and minimizing waste, the cutter will work with the pointed rough and add facets.

DIAMOND CUT AND REFLECTION

Knowing how light behaves inside a diamond helps us understand diamond cuts. There are three main ways to classify diamond sparkle.

Dispersion
, or fire, separates colored light into its full spectrum. While white light enters and exits through the table, flashes of color are visible when the light is emitted from the center. This is done through the crown.

Brilliance. The amount of white light emitted and reflected out of a diamond determines its brilliance. Diamonds absorb natural light, then split it into the full spectrum of colors thanks to their wide top table. As the light bounces back and reflects within the diamond, it is projected upwards and leaves the table as pure white light.

Scintillation. A diamond's scintillation refers to how light bounces off its facets when moved, creating a glistening and twinkling effect. Light will emanate from diamonds when they are well cut, creating the mesmerizing sparkle we all love.

WHY IS DIAMOND CUT IMPORTANT?

An Excellent diamond cut will enhance the appearance of other qualities of the stone, like the color and clarity grade. It can even make a diamond appear larger. When a diamond is cut to an Excellent (GIA) or Ideal (IGI) grade, the polish and proportions of the stone will produce brilliance, fire and scintillation that work together in harmony, creating a charmingly sparkly diamond.

How does the sparkle of an princess cut diamond compare?

An oval or oval modified brilliant has beautiful brilliance that’s similar to a round diamond. The oval is seen most frequently cut in the standard 58 facet brilliant pattern, but can have a varying number of pavilion main facets.

Do Princess Cut Diamonds look bigger than other shapes?

Princess cuts tend to look slightly smaller than other diamonds of a similar carat weight because of their square length-to-width ratio. A princess cut has a smaller diameter and surface area. 

Which diamond shape is the rarest?

It is more difficult to find some diamond shapes than others. The demand for asscher diamonds and radiant diamonds is much lower than for other diamond shapes, making them rarer than most diamond cuts. They are followed closely by marquise and hearts.

What diamond shape is the most popular?

Due to many of the reasons already stated, the round brilliant diamond continues to be the most popular diamond shape in the United States. Followed by oval diamonds, pear diamonds, emerald cut diamonds, and cushion cut diamonds.
