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.


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.


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.


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:

Emerald Cut Engagement Rings

Posted on May 22,2014

Emerald cut engagement rings are a popular option for people who are looking for a unique alternative to the more popular round brilliant engagement rings and princess cut engagement rings. While emerald cut diamonds don’t have as much fire and sparkle as round brilliant diamonds, the long lines that appear on its surface as a result of its step cut lends to its sophisticated appeal. While the emerald cut was originally intended for emeralds, diamond cutters found that the same cut can be applied to diamonds and produce an equally elegant effect.

Emerald cut diamonds are also generally cheaper compared to round brilliant diamonds of the same caliber. An emerald cut diamond is typically rectangular in shape but there are some emerald cuts that are squarer than most and are almost indistinguishable from the assher cut.

Selling Emerald Cut Engagement Rings

If you have an emerald cut engagement ring that you would like to sell, you might want to consider selling to a reputable online diamond buyer especially if you’re looking to get a decent price for your ring. Since round brilliant diamonds account for about 75% of all diamond sales, if you sell to a pawnshop or jeweler, you might not get as much for your ring because they pay higher for diamond cuts that have a higher demand. Online diamond buyers are able to offer better prices because they have access to a larger market compared to local jewelers and pawnshops. Inclusions and color are also much more visible on an emerald cut diamond compared to a round brilliant diamond so it might be more difficult to sell at a fair price especially for stones that are of a lower-grade.

Buying Emerald Cut Engagement Rings

The pricing for emerald cut engagement rings might put a seller at a disadvantage but if you’re buying an emerald cut engagement ring, it’s easier to get a better stone for a much lower price than if you buy a round brilliant diamond. This also means that you can get a bigger stone for the same price of a smaller round brilliant diamond.

Emerald cut diamonds can be elegant in any setting. Due to its rectangular shape, the diamond can stand out on its own or even with accent diamonds as it usually appears larger than round brilliant cuts in the same setting.

If you’re in the market for an emerald cut engagement ring, we suggest that you set some specifications beforehand so that you know exactly what you want and what you’re willing to settle for in terms of pricing. Aside from carat and color, you should pay extra attention to clarity and cut because inclusions and flaws are more visible to the naked eye with emerald cut diamonds.


When considering the cut quality of your emerald cut diamond, it’s safe to set a minimum standard of “Good”, although an “Excellent” cut is ideal, these diamonds can be very expensive.

Take a look at the table percentage, depth percentage, girdle, and culet. We recommend that you set the following values as your minimum standards if you want a diamond that has a good cut:

Table Percentage: 58%

Depth Percentage: 57%

Girdle Thickness: Very thin to thick (0.4% to 5.5%)

Culet: Small

Length-to-width Ratio

The ideal LW ratio for rectangular cuts is 1.20 to 1.50 but this will depend on your personal preference. A perfect LW ratio for rectangular cuts is 1.50. If you prefer a squarer cut, you should look for a LW ratio of 1.00 to 1.05.


As previously mentioned flaws are more obvious in emerald cut diamonds than round brilliant diamonds so it’s best if you set a minimum standard of VS2 (very slightly included) for your diamond.


Color is subjective so this will depend entirely on your preference. However, if you’re looking for a colorless emerald cut diamond, the minimum color you should go for is a G-color emerald cut diamond unless you don’t mind a bit of yellow on your diamond (which others actually prefer).

Where to Buy

If you’re not sure what to look for, you may want to consider the following emerald cut diamond engagement rings from Blue Nile. They have wide selection of emerald cut diamonds and settings suitable for a variety of preferences and a range of budgets. You can choose your own setting for a more personalized engagement ring.

What is an Emerald Cut Diamond?

Posted on May 20,2014

Emerald Cut DiamondAn emerald cut diamond is classified as a fancy shape diamond. It is a step cut stone and as such, it is not as fiery or brilliant as round brilliant or princess cut diamonds. Due to the cutting process, the surface produces a “hall-of-mirrors” effect and while it does not have as much sparkle as other diamond cuts, the long, crisp lines on its surface give off elegant flashes of light that add to its elegance and unique appeal.

As the shape’s name suggests, the emerald cut was originally developed to cut emeralds but when applied to diamonds, the result is as stunning as when used on an actual emerald stone.


Shape and Length-to-Width Ratio

The emerald cut is traditionally rectangular in shape, although some emerald cuts are squarer than they are rectangular. Square emerald cuts are very similar to the asscher cut.

The perfect length-to-width ratio of a rectangular emerald cut diamond is 1.50. If you want the classic rectangular emerald cut, you should look for a LW ratio of 1.30 to 1.50, although a LW ratio of 1.20 is still acceptable.

However, if you want a square emerald cut diamond, you should look for a diamond with a LW ratio of 1.05 to 1.00. A perfect square has a LW ratio of 1.00.


While colorless diamonds in the D to F range are considered rare and are more favorable to most consumers, color is a subjective matter and some customers may prefer emerald cuts with a tinge of yellow. If you want an almost colorless diamond, you can set the minimum at J-colored emerald cuts. For smaller stones that are less than .50 carats, D to G colored diamonds are considered excellent and for stones larger than .50 carats, D to F are considered excellent.


Most step cut diamonds like emerald cut diamonds emphasize its clarity rather than its fire and brilliance. This is why when choosing an emerald cut diamond, it is best if you prioritize clarity over carat weight especially since inclusions and other flaws are more visible on an emerald cut diamond than they are on other cuts. For an emerald cut diamond to appear flawless to the naked eye, it is recommended that you set a minimum clarity of VS2 on an emerald cut, as inclusions are already visible on diamonds in the SI1 range unless they are smaller than .50 carats.


Well-cut emerald diamonds usually look bigger from the surface compared to other cuts like round brilliants and princess cuts. When looking at the cut quality, pay close attention to the following aspects:

Table Percentage

Emerald cut diamonds with a table percentage ranging from 56 to 60 are classified under the good to very good range and those within the 61 to 69 range are classified as excellent.

Depth Percentage

Excellent: 61 to 67

Very Good: 59 to 60.9

Good: 57 to 58.9


Excellent to Very Good: Very Thin to Slightly Thick

Good: Very Thin to Thick


Excellent: None

Very Good: Very Small

Good: Small

Price of Emerald Cut Diamonds

Emerald cut diamonds are cheaper than round brilliant cuts or princess cuts. Since they appear bigger than round brilliant cuts of the same carat weight, people who prefer larger looking diamonds find the emerald cut a favorable choice. You can also get more for your money in terms of carat weight and clarity for an emerald cut diamond than a round brilliant cut.

An emerald cut diamond can look stunning when placed in any setting. Even smaller sized emerald cuts can look bigger next to accent stones in the right setting. Cathedral settings or classic solitaire settings are also good options if you want to make the stone look bigger.
