In the search for maximum radiance and brilliance, the round cut has gone through extensive experimentation. The cut was materialized only after the invention of the Bruting machine in the 1800s, which was used for diamond cutting.
Then, it underwent various modifications before a major overhaul in 1919. Marcel Tolkowsky's thesis on the science behind diamond's light reflection and refraction shed new light on magnifying the sparkle of these stones.
Round diamonds are brilliant-cut jewels with 58 facets, which are arranged equally around the stone. Due to the visual symmetry, this type of gemstone has made it very popular for use in engagement rings. The round cut diamond allows light to enter from all angles, making it sparkle more than other cuts that only reflect light from one or two angles.
During the evolution of round diamonds, there have been at least six distinct cuts, including:

Also known as the Tolkowsky Brilliant, the measurements for this cut are regarded as the ideal specification for cutting a round diamond in the United States. Marcel Tolkowsky invented this cut and it displays excellent brilliance and fire.
Practical Fine Cut

Just like the Tolkowsky Brilliant cut is the American standard, the Practical Fine cut is the benchmark in various European countries. This cut utilizes even the light that enters the diamond at an angle. The crown by pavilion height ratio is 1 : 3.0. The crown height, pavilion depth, and table diameter measurements are only slightly different from the American Standard.

With a 10.5% crown height of the girdle diameter, this cut has the least crown depth of all types. For this reason, Parker Brilliant shows the lowest brilliance among all round diamond cuts. Its crown to pavilion height ratio is 1: 4.13.
Another cut that does not display much sparkle. This time, the reason for the sub-par performance is utilizing the light falling upright on the stone. It does not account for the light falling slantwise.
With a crown by pavilion height ratio of 1: 2.95, this cut was the invention of W. R Eulitz. He figured out the mathematical measurements for optimizing the brilliance of the stone.
There are two widely recognized cut in the diamond industry for round diamonds. The brilliant-cut round diamonds offer a beautiful sparkle by highlighting white light. On the other hand, the old European cut was an older style that was popular before the 20th century. The cut brings a vintage look to the stone and highlights the carat size instead of the brilliance.

Why Are Round Cut Diamond Engagement Rings The Most Expensive Engagement Rings?

The round cut diamond are the most expensive cut because they are in high demand. There are some uncommon and fancy styles like cushion cut, princess cut, and rose cut but round diamonds are the most desirable and sought-after cuts. Since it's not possible to supply diamonds at a moment's notice, the high demand allows the sellers to ask for a premium price.
Another reason for its staggering price is the high percentage of rough diamond wastage. The mined diamond's shape is not perfect for cutting a round stone and must be polished and adjusted before it can be cut. This can lead to a lot of waste, which drives up the cost, making the round cut the most expensive product on the market.

Diamond cutting is a complex and labor-intensive process. Cutting 58 facets for the maximum fire and brilliance is not an easy task. Yielding a high-quality round diamond takes expertise and time, which results in higher overhead costs.
Compared to any popular style, including oval cut, Asscher cut, and pear shaped diamonds, round cut diamonds are at least 20% to 40% more expensive, considering all other features are similar.
Round Cut Diamond Engagement Rings Vs Princess Cut Engagement Rings: The Differences

Round cut and princess cut diamonds are both beautiful and popular diamond shapes, but there are some differences worth noting.
Origin And Popularity

Featuring a classic shape, the round diamonds have been around the 17th century. The style has gone through several changes, mainly for inventing a cut that displays the maximum sparkle and brilliance.
The princess cut, on the other hand, is a newer style that was invented in 1961. After several changes in the cut, the current shape has been finalized in 1980.
A round brilliant diamond is the most popular cut of diamonds in the world, whereas the princess cut comes second in this regard.
Shape And Sparkle
The round cut, as the name suggests, looks completely round. Known for its remarkable precision and symmetry, the diamond has 58 facets that refract light from all angles. For this reason, no other gemstone comes close to producing the intense white sparkle of round brilliant diamonds.
With a square or slightly rectangular shape, a princess cut diamond looks like an inverted pyramid. It also has 58 faces and offers bright sparkle but that is not enough to beat the brilliance of round diamonds. In fact, this cut reflects 70% of the light that goes through it, while a round diamond reflects 90% of light.
Both cut styles are good at concealing color and blemishes in the diamonds. This allows you to purchase a less expensive stone with a lower clarity and color grade. However, a round brilliant does this job better because of its better light refraction rate.
A round cut diamond engagement ring is the most expensive of all styles. So, a princess cut is a more suitable option if you are on a budget. The price will be even lower if the princess diamond is slightly rectangular or has an irregular shape.
Comparing Between Round Cut Diamond Engagement Ring Vs Marquise Cut

Marquise and round cut diamonds are quite dissimilar in their appearance and performance. If you want to make a decision between the two, check these differences:
A round diamond is cut to show a round shape. It is quite symmetrical and the cutting of all facets is precise. Symmetry is the key to the cut of marquise diamonds too but they resemble the shape of a boat or eye.
Image via Rockher
A round diamond reflects 90% of light passes through it. No other cut style can replicate this performance. Marquise diamonds sparkle too because of being a modified brilliant cut but it's way less than the dazzling sparkle of round diamonds.
Marquise diamonds are unique in the sense that they give the illusion of being bigger than their actual carat weight. However, round diamonds don't look that much bigger as the marquise cut.
Because of their worldwide popularity, round diamonds are readily available. Compared to this, marquise diamonds are hard to find because of a limited supply.
Despite the rarity, the marquise cut is as inexpensive as emerald cut stones. But the round cut is the most expensive of all diamonds.
Best Color Grade For Round Cut Diamond Engagement Rings

When it comes to which color grade to choose for round cut diamonds, the answer is often quite personal. Some prefer a higher color grade to make their diamond look colorless and sparkle more brightly. Others like the lower grades because they are less expensive.
The D-F (colorless) diamonds are highly popular and expensive. However, you can choose a lower color grade too because round diamonds hide color well with brilliant sparkle. So, you can easily go with an H, I, or lower color grade and save a handsome amount of money. Just because you're on a budget doesn't mean you have to sacrifice quality.

When selecting a color grade for a round diamond, it is important to choose a color that will complement the ring's setting. A white gold or platinum band is perfect for J or higher color, as these diamonds have minimal hints of color. If you plan to use gold settings, go for K or L because the slight yellowish tone will complement the band's color.
What'S The Best Clarity For A Round Cut Diamond?

The best clarity for round cut diamonds is an eye-clean diamond, which does not show any inclusions to the naked eye. It's easier to find an eye-clean round diamond because this cut is the best at disguising flaws.
For a half-carat diamond ring, you can choose the SI2 clarity without thinking twice. It will appear eye-clean unless you are looking at it through a loupe. For a 1 to 1.5-carat diamond, SI1 clarity is fine, as it won't show any inclusion.
However, if you are looking to purchase a large diamond (bigger than one and a half carat), go for the VS2 clarity for having a clean surface.
Upgrading from one clarity grade to another will make the price tag take a big jump. And you don't really need a high clarity when it's a round diamond. Its excellent brilliance and sparkle will cover up all blemishes unless they are too noticeable.
The Perfect Dimensions For Round Cut Diamonds

The sparkle of a round cut diamond is enchanting and much of it depends on the perfect shape. A perfect ratio is an essential part of a diamond's beauty and value. You obviously don't want the precious stone to look bulky and distorted.
Diamonds with a length-to-width ratio between 1:1 and 1:1.03 will be considered most desirable. This ratio will embody excellent proportions, creating a beautiful round shape. Don't choose one with a width ratio above 1.05. The ring will have a strange appearance because the stone won't be a perfect round.
For other measurements, you can follow the dimensions of the American Standard cut. In this cut, the table diameter is 53% of the girdle, which ensures a magnificent amount of white sparkle or brilliance. A larger table is good for brilliance, while a smaller table creates more fire than sparkle.
Image via Tiffany
For the maximum brilliance, the crown height should be 16.2% of the girdle diameter and that percentage has to be 43.1 for the pavilion depth.
The crown and pavilion angle has to be precise because it helps with creating sparkle by returning light. For this cut, 40.8° pavilion and 34.5° crown produce the best white sparkle. The angles could be different too. You just have to make sure that the crown height by pavilion depth ratio is 1 : 2.6.
The Best Settings For A Round Cut Diamond Engagement Ring
Round cut stones are extremely versatile — they will work in pretty much any ring style, from standing alone in a solitaire to being the center-stone in a blingy round halo setting. No matter the setting chosen, a round brilliant stone will always work.
If you are looking for a suitable style, choose one from the following options:

A round cut diamond mounted in a solitaire setting can be used with an 18-karat gold band. This type of ring is simple and elegant with the diamond on top of the ring with no side stones.
A solitaire setting is not only less expensive than other options but also creates the optimum sparkle by allowing passing the maximum light.
If the stone is large (over 2 carats), use a prong setting for the solitaire diamond. Both 4 and 6 prong styles will look good and keep the stone secure to the band.|

Pavé setting for round diamond rings is a popular and unique style. With this intricate and delicate setting, the ring will alter the appearance of a traditional solitaire engagement ring to give it a contemporary look. The ring band has multiple tiny diamonds that make the whole ring sparkle and shine with a beautiful gleam.

If you find yourself looking for a ring setting that complements your center stone, you might want to consider the Halo setting. The balance of the ring is created by the band that circles around the center diamond. This band could be of metal, small diamonds, or other gemstones, which reflect light off of the ring in a way that makes the center stone appear larger.
The center stone becomes more noticeable and eye-catching when it's paired with a halo setting around it.
