Oval-Cut vs. Round Cut: Which Diamond Shape Is Right for You?

When it comes to selecting the perfect diamond for your engagement ring or fine jewelry, the shape you choose plays a significant role in determining the overall aesthetic and brilliance of the gem. Two of the most popular and timeless diamond shapes are the oval cut and the round cut, each offering unique charm and appeal.


In this blog, we’ll delve into the distinctive features, advantages, and considerations of these two diamond shapes to help you make an informed decision that aligns with your style and preferences.

Distinctive Features of Oval and Round Cut Diamonds

Oval Cut Diamonds

The oval cut diamond is characterized by its elongated, elliptical shape which creates an illusion of a larger size per carat weight compared to round diamonds. This shape offers versatility in length-to-width ratios, allowing you to choose the degree of elongation that best complements your desired aesthetic.


However, it’s important to note that some oval diamonds may exhibit a distinctive bow-tie effect, which refers to a darker area across the center of the diamond when viewed from certain angles.

Round Cut Diamonds

Round-cut diamonds are renowned for their unmatched brilliance and sparkle, thanks to their symmetrical cut and intricate facet pattern. These diamonds are meticulously crafted with expert artisans cutting away a significant portion of the rough diamond to achieve the perfect round shape.


This labor-intensive process, coupled with the high demand for round diamonds, often results in a higher price point compared to other diamond shapes.

Advantages and Considerations

Impact on Ring Design and Overall Aesthetics

The choice between an oval or round diamond shape can significantly influence the overall aesthetic of your ring design. Oval diamonds offer a sleek and elongated look, often complementing slender and delicate ring styles. They can create a visually flattering effect by elongating the appearance of the wearer’s fingers.


In contrast, round diamonds are the quintessential choice for classic and timeless ring designs, such as solitaire or pavé settings. Their symmetrical shape and unmatched brilliance make them the perfect centerpiece for traditional and contemporary designs alike.


When considering the overall aesthetic impact, it’s essential to envision how the diamond shape will complement your style and the specific ring design you have in mind.

Practical Considerations

In addition to aesthetic preferences, there are several practical considerations to keep in mind when choosing between oval and round diamond shapes.

1. Visibility of Imperfections

Oval diamonds tend to be more forgiving when it comes to concealing inclusions or imperfections within the diamond. Their elongated shape can make imperfections less noticeable to the bare eye. On the other hand, round diamonds require a higher degree of precision and care as any imperfections are more readily visible due to their symmetrical shape.

2. Color Grades

Both oval and round diamonds are available in a range of color grades from colorless to fancy colored diamonds. However, the elongated shape of oval diamonds can make them appear slightly darker in color than round diamonds of the same grade. Therefore, it’s generally recommended to opt for a slightly higher color grade when selecting an oval diamond to maintain optimal brightness and brilliance.

3. Performance in Various Lighting Conditions

While both diamond shapes can dazzle in various lighting environments, round diamonds are often considered the superior choice when it comes to maximizing brilliance and sparkle. Their symmetrical cut and facet arrangement are specifically designed to optimize light reflection and dispersion, resulting in an unmatched level of brilliance, particularly in well-lit environments.

4. Precision in Grading

Due to their symmetrical shape, round diamonds require a higher level of precision in grading and evaluating their cut quality. Slight deviations from perfect symmetry can significantly impact their light performance and overall appearance. Oval diamonds, while still requiring expert grading, may be less sensitive to minor variations in cut quality.


Choosing between an oval or round diamond shape is a deeply personal decision that should reflect your style, budget, and preferences. While round diamonds are the quintessential choice for their unmatched brilliance and timeless appeal, oval diamonds offer a unique and modern look that can create the illusion of a larger size while providing cost-effectiveness.

Ultimately, the best way to make an informed decision is to view these diamond shapes in person and observe how they interact with various lighting conditions and ring settings. Work closely with a reputable jeweler who can guide you through the process and ensure you select a diamond that meets your specific criteria.

Remember, the true beauty of a diamond lies not only in its shape but also in the emotional connection it represents. So, take your time, consider all the factors, and choose the diamond shape that speaks to your heart and reflects your journey.

1. Which diamond shape looks bigger for the same carat size?

Oval diamonds typically appear larger than round diamonds of the same carat weight due to their elongated shape and greater surface area.

2. How can I avoid the bow-tie effect in oval diamonds?

To minimize the visibility of the bow-tie effect, it’s essential to inspect the diamond in person or request high-quality images and videos from your jeweler. The bow-tie effect can vary significantly between individual diamonds, so evaluating each stone carefully is crucial.

3. Why are round diamonds generally more expensive than oval ones?

Round diamonds are often more expensive due to the high demand for their classic shape, as well as the labor-intensive process required to achieve the perfect symmetrical cut. A larger portion of the rough diamond must be cut away, resulting in a higher cost per carat.

4. Can I mix and match diamond shapes in a ring design?

Absolutely! Many modern ring designs incorporate multiple diamond shapes, such as a round center stone with oval accent diamonds or vice versa. This can create a unique and visually striking look, allowing you to combine the best of both worlds.

5. Are oval or round diamonds better for an engagement ring?

There is no definitive better choice for an engagement ring – it ultimately comes down to personal preference and style. Round diamonds are a classic and timeless option, while oval diamonds offer a modern and elongated look. Consider your partner’s preferences, ring design, and overall aesthetic to make the best choice.
