A round-cut diamond engagement ring is the ‘no-second-thoughts’ kind of pick for all those in love and planning to propose a lifetime of commitment to their partner. Most women, regardless of the demographic, love to be proposed to with a glistening round diamond engagement ring (one carat or more) dazzling right into her face while the man goes down on his knee confessing his love. We unravel every aspect of this gorgeous diamond cut that makes it worth all the adulation!

Round-cut diamonds have remained the most popular choice for engagement rings for decades. While contemporary and distinct tastes may gravitate women toward other fancy diamond shapes, such as princess or pear cut, round diamond unrelentingly retains the top spot. Here are a few reasons why women adore this diamond cut so much:

1. They are timeless and classic. Round-cut diamonds have been around for centuries and have a timeless, classic look that never goes out of style. They are a safe choice for those who want a traditional and elegant look for their engagement ring.

2. They are versatile. Round-cut diamonds can be set in various ring styles, from simple solitaires to intricate vintage-inspired designs. This versatility makes them ideal for women who want a ring that matches any outfit or occasion.

3. They are sparkly and eye-catching. Round-cut diamonds are known for their exceptional sparkle and brilliance due to how they are cut. The faceted sides and top of the diamond reflect light in all directions, creating a dazzling display of fire and sparkle. This makes them perfect for women who want their engagement ring to stand out for its shine.

4. They are a good value. Round-cut diamonds are often more affordable than other diamond shapes, as they are the most popular and, therefore, the most widely available. This makes them a good value for those looking for a high-quality diamond at a more reasonable price.

5. They are suitable for any finger size or shape. Round-cut diamonds are perfect for those with small or plump fingers, as the circular shape of the diamond makes the finger look longer and slimmer. They are also a good choice for those with larger fingers, as the circular shape helps balance the finger's length and create a more proportional look.

6. Round-cut diamonds are easy to care for and maintain, as they have a simple and classic design that doesn't require too much looking after. This makes them a wonderful choice for those who want a low-maintenance ring they can wear daily.

First, let's define a round-cut diamond. A round-cut diamond, also known as the round brilliant, is a diamond that has been cut into a circular shape with 58 facets (57 if you don't count the culet). The facets are the flat surfaces on the diamond that reflect light, and the number and arrangement of the facets is what gives the diamond its sparkle and brilliance.

The anatomy of a round-cut diamond can be broken down into several key parts: the crown, the girdle, the pavilion, and the culet.

The crown is the top portion of the diamond, and it consists of the table (the flat top surface of the diamond), the bezel facets (the eight facets that surround the table), and the star facets (the eight facets that radiate out from the center of the diamond). The crown is responsible for much of the diamond's brilliance and fire, and it's also what makes the diamond visible to the naked eye.

The girdle is the thin outer edge of the diamond that separates the crown from the pavilion. The girdle can be either faceted (meaning it has a series of small, flat surfaces) or unfaceted (meaning it's smooth and polished). The girdle plays a crucial role in the diamond's overall stability and durability, as it helps to protect the diamond from damage. 

The pavilion is the lower portion of the diamond and it consists of the lower half of the diamond below the girdle. The pavilion is made up of a series of faceted planes that taper down towards the culet. The pavilion is responsible for much of the diamond's fire and dispersion (the rainbow-like colors that are visible when the diamond is viewed from certain angles).

The culet is the very bottom of the diamond, and it's the smallest and least visible facet of the diamond. The culet is often left unfaceted, but some round-cut diamonds have a very small facet on the culet to help protect the diamond from damage. 

In addition to these main parts, round-cut diamonds also have other characteristics that contribute to their beauty and value. One of these is the diamond's cut grade, which refers to the overall quality of the diamond's cut. A well-cut round-cut diamond has a high degree of symmetry and is perfectly balanced in terms of the size and placement of its facets. A poorly cut round-cut diamond, on the other hand, often lacks symmetry and does not sparkle as brightly as a well-cut diamond. 

Another important characteristic of a round-cut diamond is its clarity grade, which refers to the presence or absence of inclusions (minor blemishes or imperfections) within the diamond. A diamond with a high clarity grade has fewer and smaller inclusions, which makes it more valuable and visually appealing.

The color grade of a round-cut diamond is also an essential factor to consider. Diamonds are rated on a scale from D (colorless) to Z (light yellow), with D being the most valuable and rare. A round-cut diamond with a high color grade is more valuable and desirable than a diamond ranking lower on the color scale.

When it comes to purchasing a round-cut diamond, there are several factors to consider in order to ensure that you are getting the best value for your money. Here are some key points:

1. Carat Weight: The carat weight of a diamond refers to its size and is typically the most obvious factor when it comes to determining the diamond’s value. Larger diamonds are rare and, therefore, more valuable, but it's important to keep in mind that carat weight is just one factor among many.

2. Cut Quality: The cut quality of a diamond refers to the way in which the diamond has been cut and polished. A well-cut diamond has a greater sparkle and brilliance and is generally considered to be more valuable. When shopping for a round-cut diamond, look for one that has a good or excellent cut quality rating.

3. Color: Diamonds are rated on a scale from D (colorless) to Z (light yellow). Diamonds with a higher color rating are generally more valuable, as they are rarer and have a higher level of clarity. When shopping for a round-cut diamond, aim for a color rating of D, E, or F if possible.

4. Clarity: The clarity of a diamond refers to the presence of inclusions, or internal blemishes, that affect the appearance of the diamond. Diamonds with a higher clarity rating are generally more valuable, as they are clearer and have fewer inclusions. When shopping for a round-cut diamond, aim for a clarity rating of VS1 or higher.

5. Certification: It's important to ensure that the diamond you are purchasing has been certified by a reputable organization such as the Gemological Institute of America (GIA). A GIA certification provides you with detailed information about the diamond's characteristics, including its carat weight, cut quality, color, and clarity.

6. Setting: The setting of a diamond refers to the way in which it is mounted in a jewelry piece. Different settings affect the appearance of the diamond, so it's important to consider the setting when shopping for a round-cut diamond.

7. Budget: Finally, it's important to have a clear budget in mind when shopping for a round-cut diamond. Diamonds vary significantly in price, so it's important to determine your budget and stick to it in order to avoid overspending.

Choosing the right setting for your round-cut center diamond can be overwhelming, as many options are available. Let us take you through some stunning setting options that will help you decide which one to choose for your ring.

Let's start with the basics. A diamond setting is the design style in which the diamond is held in place on the ring. It can be a simple band or a more intricate design with multiple diamonds or other gemstones. The setting plays a significant role in the overall appearance and style of the ring, so choose one that complements your personal taste and the shape and size of your diamond.

The solitaire setting is one of the most popular settings for a round-cut diamond. This classic setting features a single diamond on a slender band, allowing the diamond to take center stage. Solitaire settings can be simple and understated or more ornate, with decorative details on the band. This setting is perfect for those who want a classic and elegant look.

Another popular setting for a round-cut diamond is the halo setting. It features a circle of smaller diamonds or gemstones around the center diamond, creating a halo effect. The halo setting adds extra sparkle and dimension to the ring, making the center diamond appear larger. It is also a great option for those who want a more vintage or romantic look.

A three-stone setting, also known as a trilogy setting, is another option for a round-cut diamond. It features three diamonds, with the center diamond being slightly larger than the two side diamonds. The three-stone setting symbolizes the past, present, and future, making it a meaningful and sentimental choice for an engagement ring.

A pavé setting is another option for a round-cut diamond. In a pavé setting, a series of small diamonds or gemstones closely set together surround the center diamond, creating a "pavéd" effect. The pavé setting adds extra sparkle and shine to the ring and is a great choice for those who want a more glamorous and modern look.

A bezel setting is a more secure and protective setting for a round-cut diamond; the diamond is encased in a metal rim, with the diamond sitting flush against the metal. This setting provides added protection for the diamond, as it is less exposed than in the case of other settings. However, it can subdue the sparkle and brilliance of the diamond a bit, so it may not be preferred by those who like glaring bling.

A twisted setting is a unique and modern setting for a round-cut diamond. While putting the center stone in the spotlight, the curvaceous silhouette of the shank lends it a distinct appeal. The intertwined bands also symbolize the love and harmony between the couple and their commitment to a lifelong union. Overall, the unconventional twisted shank beautifully complements the simplicity and timelessness of the round-cut diamond.

When finalizing the stone setting, consider your aesthetic taste and the characteristics of the diamond, such as its size and shape. Also, consider the metal type, as different metals affect the overall appearance and durability of the ring.

Ultimately, your chosen setting should reflect your unique relationship and innate style.

If you’re in the process of choosing a diamond engagement ring, you’ve likely come across the terms “prongs” and “bezel.” These terms refer to the way in which the diamond is set in the ring. The setting is an important consideration, as it affects the overall appearance and durability of the ring. So which setting is best for a round-cut diamond? Let’s take a closer look at prongs and bezel settings to help you make an informed decision.

Prong Setting

A prong setting is a popular choice for diamond engagement rings. It involves using several thin, pointed pieces of metal (called prongs) to hold the diamond in place. The prongs are typically placed at the four corners of the diamond, though they can also be placed along the edges.

There are several advantages to a prong setting. Firstly, it allows for a lot of light to reach the diamond, which makes it appear brighter and more sparkling. This is because the prongs are relatively thin and do not obstruct the light from entering the diamond. Secondly, a prong setting makes the diamond appear larger, as the prongs lift the diamond up off the finger and allow it to “float” above the band. This is especially appealing if you want your diamond to stand out and make a statement.

However, there are also some potential drawbacks to a prong setting. One concern is that the prongs can become loose over time, which could cause the diamond to fall out. To prevent this, it’s important to have the prongs checked and tightened by a jeweler regularly. Additionally, the prongs can be prone to catching on clothing or other materials, which could lead to damage or even the loss of the diamond.

Bezel Setting

A bezel setting involves using a metal rim or band to encircle and secure the diamond. The diamond is set into the bezel, and the metal is shaped and molded around it, creating a seamless, smooth surface.

One of the main advantages of a bezel setting is that it offers a high level of protection for the diamond. There is minimal risk of the diamond falling out or getting damaged as it is completely encircled by metal. This attribute is especially appealing if you have an active lifestyle or plan to wear the ring frequently.

In addition to its durability, a bezel setting creates a sleek and modern look. Because the diamond is set close to the band, it creates a more streamlined appearance. The bezel setting is a good choice if you prefer a more understated or minimalistic style.

On the downside, a bezel setting does not allow as much light to reach the diamond as a prong setting. This makes the diamond appear less sparkling and also somewhat smaller. Additionally, a bezel setting does not show off the diamond as much as a prong setting, as it is more enclosed.

So, which setting is best for a round-cut diamond?

Ultimately, the decision of which setting to choose depends on your personal preference and lifestyle. If you want a setting that maximizes the sparkle and size of the diamond, the prong setting is the way to go. However, a bezel setting is a better choice if you prioritize durability and protection for the diamond.

It’s also worth considering the type of metal you want for your ring. For example, a bezel setting is more suitable for a softer metal such as gold, as it offers more protection for the diamond. On the other hand, a prong setting is better suited for a harder metal such as platinum as it can withstand the pressure of the prongs holding the diamond in place.

Round-cut diamonds, also known as brilliant-cut diamonds, are the most popular and sought-after diamond cuts. These diamonds are known for their sparkling, dazzling appearance, which is achieved through their precise cuts and symmetry. The round-cut diamond is the most expensive of all diamond cuts, and there are several reasons behind that.

One reason round-cut diamonds are so expensive is because of the amount of material lost during the cutting process. These diamonds are cut using a specific pattern of 57 or 58 facets, which are small, flat surfaces cut into the diamond. The facets are arranged in a specific way to reflect and refract light, creating the diamond's sparkle. However, cutting the facets into the diamond requires precise skill and attention to detail, and it also removes a significant amount of the diamond's original material. This material loss is called the "diamond yield," and it can be as high as 50% for round-cut diamonds. This means that a 1-carat round-cut diamond actually starts out as a 2-carat rough diamond before it is cut and polished.

Another reason round-cut diamonds are so expensive is due to their high demand. These diamonds are popular for engagement rings, wedding bands, and other special occasions, and they are often seen as a symbol of love and commitment. As a result, there is a constant demand for high-quality round-cut diamonds, which drives up their price.

Round-cut diamonds are also expensive because their creation requires a high level of craftsmanship to create. The process of cutting and polishing a round-cut diamond is highly skilled work that requires years of training and experience. Diamond cutters must have a deep understanding of the properties of diamonds and the various techniques used to cut and polish them. This level of expertise is reflected in the price of round-cut diamonds.

Finally, the price of round-cut diamonds is affected by market conditions and the overall supply and demand for diamonds. When the demand for diamonds is high, and the supply is low, the price of diamonds tends to rise. Conversely, when the demand is low, and the supply is high, the price of diamonds tends to fall.

Despite their high price, round-cut diamonds are highly sought after for their sparkling, dazzling appearance and their timeless elegance.

When choosing a wedding band to go with a round-cut diamond engagement ring, there are a few factors to consider. The most important is to find a band that complements the engagement ring's shape and style. Here are a few popular wedding band styles to consider pairing with a round-cut diamond engagement ring:

1. Classic Diamond Wedding Band: A classic band is a simple, timeless option that will never go out of style. It is a simple band that is either plain or has a subtle design, such as a single row of diamonds. This band type complements a round-cut diamond engagement ring because it lets the ring be the center of attention while enhancing the grandiosity with further shine and sparkle.

2. Two-Tone Wedding Band: A two-tone band is made of two different types of metal: white gold and yellow gold or white gold and rose gold. This band design adds to the visual impact of the overall look and is a good option if you want to incorporate your partner's favorite metal into the design. A two-tone band works well with a round-cut diamond engagement ring because it adds some contrast and helps the ring stand out. Ensure that the engagement ring and the wedding band's metals align.

3. Eternity Band: An eternity band is a continuous band of diamonds that goes all the way around the finger. It looks stunning with a round-cut diamond engagement ring, as it dramatically enhances the sparkle of the overall look. This wedding band style is a slightly extravagant option and is a good choice if you want to make a statement with your wedding band.

4. Curved Wedding Band – A curved wedding band is an excellent choice to stack with a round-cut diamond engagement ring because the curve of the band conforms to the shape of the ring's diamond, creating a more seamless and cohesive look when the rings are worn together. The curved band also helps to hold the engagement ring in place, reducing the chance of the ring spinning or twisting on the finger. Additionally, the curved band can complement the round-cut diamond's shape and add more sparkle to the overall look.

5. Colored Stone Wedding Band – A colored stone wedding band is a fantastic choice to wear with a round-cut diamond engagement ring, as it adds a pop of color and personality to the overall look. The contrast of the colored stone against the clear diamond of the engagement ring creates an interesting and unique look. Additionally, the colored stone can complement or match the bride's personal style, taste, or birthstone. The colored stone wedding band is a great way to make the ring set classier and more personal.

Ultimately, out of all the styles, the most important thing is choosing a wedding band that you love, the one that makes you feel confident and beautiful on your special day.

The second most significant attribute when choosing the center stone for the engagement ring is the carat weight of that diamond, after the shape. After all, a larger diamond is often seen as a symbol of love and commitment, and many people want to choose a center stone that makes a statement.

So, what is the perfect carat weight for a round-cut diamond engagement ring? There's no one-size-fits-all answer to this question, as it ultimately comes down to personal preference and budget. Some people prefer a larger diamond, while others prefer a smaller one. Choosing a carat weight that feels right for you and your partner is important.

One factor to consider is the size of the finger. A general rule of thumb is to choose a diamond proportionate to the finger's size. A larger diamond may look disproportionate on a small finger, while a smaller diamond may get lost on a larger finger. For example, a 1-carat diamond may look too large on a size four finger, while a 0.5-carat diamond may look too small on a size nine finger.

Another factor to consider is the diamond's cut. The round-cut diamond's ideal carat weight depends on its cut quality. A diamond with a higher cut quality has a better balance of fire and brilliance and looks larger than a diamond with a lower cut quality. Therefore, a diamond with a higher cut quality looks larger with a smaller carat weight.

In addition to personal preference and finger size, budget is also a key factor in determining the perfect carat weight for a round-cut diamond engagement ring. Diamonds are priced based on the "Four Cs" - cut, color, clarity, and carat weight. The larger the diamond, the more expensive it is. Therefore, it's important to choose a carat weight that fits within your budget.

Remember, the most important thing is that the engagement ring symbolizes your love and commitment, so choose a diamond that is meaningful and special to you.
