Comparing Princess Cut Diamonds & Radiant Cut Diamonds

Posted on Oct 24,2014

Princess cut and radiant cut diamonds share some similarities. Both are square cuts and both have a complete brilliant-cut pattern. When set on a ring, these two cuts can easily be interchanged at first glance.

Choosing between the two can be a difficult task, especially since both are superior when it comes to brilliance. You might want to compare two stones of the same carat, clarity, and color grade to determine which shape is more to your liking.

To determine the differences, let’s compare the two cuts based on the following factors:

Physical Characteristics

Princess cut is the second most popular cut next to the round brilliant. It is notable for its square shape and sharp corners. It is the first square cut to achieve the same brilliance as a round brilliant cut diamond.

While princess cut diamonds are traditionally square, there are some stones that are more rectangular than they are square. This depends on the length to width ratio of the diamond.

The radiant cut diamond is the second square cut to carry the same brilliant-cut pattern seen on round brilliant diamonds. Whereas the princess cut has sharp corners, radiant cut diamonds are square in shape with cropped corners. Its cropped corners may offer some practical advantages when it comes to stone setting.

Princess cut diamonds are always set on a prong stone setting to protect its corners from damage and chipping, an issue that is not present with the cropped corners of a radiant cut.

Princess cut diamonds also often have a larger table and more depth compared to radiant cuts.

Price and Demand

When it comes to pricing, princess cut diamonds are typically priced lower than radiant cut diamonds because there is very little waste when cutting a princess cut from the rough stone. This means that a diamond cutter can easily yield two princess cut diamonds from one rough stone with very little waste and as such, the market price is lower.

There is also a higher demand for princess cut diamonds compared to radiant cut diamonds so there is a bigger selection for the average consumer. Jewelers don’t stock up as much on radiant cuts as they do on princess cuts because of consumer demand so if you want more options, princess cut might be a more suitable choice for you.

Brilliance

A radiant cut diamond generally reflects more light than a princess cut diamond when viewed from the top. This is because when light enters a radiant cut diamond, it creates a circular pattern giving it more sparkle when it reflects light. Due to its cutting style, radiant cut diamonds also have more angles to let light in, allowing for more light to be reflected back to the surface.

Princess cut diamonds, on the other hand, are notable for its linear life. When light enters a princess cut diamond, the facets create an X in the center as a result of the contrast between light and dark facets. Due to the number of dark facets, princess cut diamonds don’t appear as sparkly as radiant cut diamonds when viewed from the top.

Radiant cut diamonds sometimes create a bow-tie effect as a result of the misalignment of facets in the diamond when light enters its surface.

Cut Quality

Princess cut diamonds are more abundant because manufacturers are able to maximize more of the rough stone during the diamond cutting process. As a result, there are more poor quality princess cut diamonds available in the market compared to radiant cut diamonds that focus more on preserving the aesthetic appeal of the stone over quantity.

Both cut styles have their own appeal and aesthetic value. In the end, it all boils down to personal preference. If price is the primary determining factor, however, princess cut diamonds are a better option because they have a cheaper per-carat price compared to radiant cut diamonds.

Guide to Diamond Cuts – Comparing Diamond Cuts

Posted on Sep 03,2014

Diamond cut can refer to two different aspects of a diamond’s physical characteristics: diamond cut grade and diamond shape. A diamond’s cut grade refers to how a diamond is cut, its proportions, polish, and symmetry whereas shape simply refers to the diamond’s physical shape (i.e. round, pear, emerald). We have discussed diamond cut grade extensively in previous posts and it has been established that the way a diamond is cut is one of the most important aspects that affects a diamond’s physical appearance. However, a diamond’s shape is just as important especially since it is one of the first things a person will notice when looking at a diamond (whether loose or set in a band).

Diamond shape is a matter of personal preference and as such, there are no fixed parameters that determine whether one shape is better than the other. One person might prefer the sparkle of a brilliant cut diamond whereas another might prefer the more subdued elegance of an emerald cut diamond.

While there is a myriad of diamond cuts available today, the most popular diamond cuts in terms of availability and demand are as follows:

Round Brilliant Cut     

The round brilliant cut is undoubtedly the most popular diamond cut today—accounting for 75% of all diamond sales. Its classic shape and ability to offer maximum fire and brilliance because of the way it is cut make it the most popular choice for many diamond buyers. It is also a very versatile shape that goes well with virtually any setting. Due to the high demand for round brilliant cuts, it is generally priced higher per carat compared to fancy cut diamonds.

Princess Cut     

The princess cut is the second most popular cut next to the round brilliant and the most popular fancy shape for diamonds. It is notable for its square shape, pointed corners, and excellent fire and brilliance. It is the closest square cut to achieve almost the same fire and brilliance as the round brilliant cut. Its shape also makes it a flexible option for many settings, although it is recommended to always set a princess cut diamond in a four-prong setting to protect its corners.

Compared to round brilliant cuts that wastes a lot of the rough stone when cut, princess cut diamonds have very little waste leading to a lower price per carat.

Emerald Cut                        

The emerald cut is adapted from the classic shape that emeralds are cut into, hence the name. It is popular for its subdued elegance, unique shape, and the hall-of-mirrors effect it creates when viewed from the surface. The emerald cut is a type of steps cut that is rectangular in shape and has cropped corners.

Since the emerald cut does not offer much fire and brilliance, inclusions and imperfections are much more visible on an emerald cut diamond compared to brilliant cuts. As such, buyers should pay extra attention to clarity when buying an emerald cut diamond especially for bigger stones.

Asscher Cut        

The Asscher cut is very similar to the emerald cut in appearance but it is square in shape instead of rectangular. While some refer to this cut as a modified emerald cut, it actually preceded the emerald cut. The Asscher cut has been in existence since 1902.

Asscher cut diamonds have larger step facets and a smaller table. It also typically has a higher crown than an emerald cut diamond. A well-cut asscher cut diamond will often deliver more brilliance than a well-cut emerald cut diamond because of its facet and table size.

Cushion Cut

Cushion cut diamonds are square in shape with rounded corners. It has been around for more than 2 centuries and used to be the shape of choice among diamond buyers. It used to be the most popular diamond shape before the round brilliant cut exceeded its demand. Due to recent cut improvements, the cushion cut is slowly regaining popularity. It is especially popular in many celebrity engagements and is typically set in a halo pave setting. While the cushion cut does not offer as much brilliance as the round brilliant cut, it typically offers more fire than other cuts.

Radiant Cut                              

Notable for its vibrancy and brightness, the radiant cut is an ideal option for those who want the fire and brilliance of a round brilliant cut but the rectangular shape of an emerald cut. The radiant cut is a brilliant cut diamond that is faceted both in the pavilion and the crown for extra fire and brilliance. While traditionally rectangular with cropped corners, some variations are squarer in shape than rectangular.

Oval       

The oval shape is a modified brilliant cut. It is very similar to the round brilliant cut in terms of the amount of fire and brilliance it exhibits when viewed from the surface. While not as popular as the round brilliant, some people prefer the oval shape because they are elongated and appear bigger even with smaller carat sizes.

Heart    

The heart shape is also a modified brilliant cut. It is very similar to the pear shape except it has two clefts on the top of each side to create an obvious heart shape. It is more popularly used in earrings and pendants. When used in engagement rings, it is not recommended to get anything smaller than .50 carats as it is difficult to notice the heart shape at all. For smaller heart shaped diamonds, a three-prong setting is recommended to accentuate its shape.

Pear      

The pear shape is another modified brilliant cut that is noted for its similarity to the round brilliant cut on one end and the marquise cut on the other end. One of the most important characteristics that any buyer should look for when choosing a pear shape diamond is symmetry. It is important for pear shaped diamonds to have excellent symmetry because of its shape. Ideally, the point at one end of a pear shape diamond should be in line with the highest part of the rounded end to achieve a perfect pear shape.

Comparison Chart for Different Cuts       

A diamond’s shape will have an effect on its physical size regardless of carat weight. Different cuts have different sizes, which is why some people prefer shapes that make a diamond appear bigger than it actually is. Below is a side-by-side comparison of the different diamond shapes and their estimated physical size, although it is worth noting that no two diamonds are the same even with the similar carat weights:

What is a Radiant Cut Diamond?

Posted on Jun 03,2014

Radiant Cut DiamondA radiant cut diamond, also known as a cut cornered modified brilliant, is a square or rectangular diamond with cropped corners. Radiant cut diamonds are famous for their fire and brilliance. It is the first square cut diamond that feature brilliant cut facets on the pavilion and crown. As such, it is recommended for those who want the brilliance of the classic round cut and the unique shape of the asscher cut or emerald cut.  Whereas an emerald cut is notable for its long lines, a radiant cut is more faceted to maximize fire and brilliance.

Rectangular radiant cut diamonds sometimes display an effect called the “bow-tie” effect. This is common in elongated diamond shapes like pear, marquise, and oval. While some people prefer a more visible bow tie that runs through the middle of a diamond, the only way to ascertain its visibility is through close inspection of the stone.

Characteristics

Cut

Like the emerald cut, radiant cut diamonds can sometimes appear square or rectangular. The ideal length to width ration of a radiant cut depends entirely on personal preference, as some people may prefer a more elongated cut whereas others may prefer a square cut.

A perfect square radiant cut has a length-to-width ratio of 1.00 but anything that is less than 1.05 will still appear square to the naked eye. Those who prefer a more rectangular cut should look for a length-to-width ratio of 1.15 to 1.30. People who are looking for a diamond that has the appeal of both a princess cut and a cushion cut might find a square radiant cut a suitable option whereas those who like the rectangular shape of a classic emerald cut but want the brilliance of a round brilliant cut would find a rectangular cut a more suitable choice.

For a well-cut radiant cut diamond, look for a table percentage of 58% to 69% and a depth percentage of 59% to 67%.

Color

Radiant cut diamonds are known for maximizing color so it may show more color than other diamond types. If you prefer a colorless diamond, look for something within the D to F range but if you prefer a warmer diamond with a tinge of yellow, you can explore diamonds within the G to K range. Radiant cut diamonds within the S to Z range may sometimes be classified as fancy yellow depending on how much color is visible on the diamond. If you prefer a fancy yellow diamond, you can look for stones within that range.

Loose Radiant Cut DiamondClarity

Since radiant cut diamonds are brilliant cuts, flaws and inclusions aren’t as visible on them as they are on emerald cut diamonds or asscher cut diamonds. As such, those in the SI1 range are still considered very good even in 1-carat stones. However, for stones larger than 1.0 carat, a minimum clarity of VS2 is recommended.

Setting

Due to its fire and brilliance, a radiant cut diamond will look good in a solitaire setting but it can also look excellent with square cornered or rounded accent stones. While the setting entirely depends on preference, it is recommended that the diamond be set with a minimum of four prongs for safety.

While not nearly as popular as round brilliant cuts, radiant cut diamonds are just as stunning as they combine the elegant appeal of princess cut diamonds and emerald cut diamonds with the shine and sparkle of round brilliants.
