Oval vs. Round Diamond: Which One to Choose?

A timeless debate between tradition and trend

When it comes to choosing the perfect diamond, especially for a special occasion, shape plays a starring role. Round and oval diamonds have long stood as two of the most beloved and elegant choices of all time. At first glance, they may seem quite similar; both are brilliant cuts, both offer stunning sparkle, but a closer look reveals unique personalities, optical effects, and even lifestyle advantages that could sway your decision.

If you're torn between the classic round and the modern oval, this guide will help you make a choice that fits both your style and story.

The Round: An Exquisite Symbol of Tradition

The round cut is a true icon among diamond shapes - timeless, radiant, and endlessly captivating. With 58 precisely aligned facets, it's crafted to reflect maximum brilliance, making it the perfect choice for those who love to outshine the moment. Simply put, few shapes rival the sparkle, fire, and elegance of a classic round diamond.

Its timeless elegance and versatility make it a favourite for everything from classic solitaires to modern halo settings. Whether worn every day or reserved for special moments, a round diamond is a celebration of brilliance, craftsmanship, and enduring style.

Pros:

  • Unmatched Brilliance: Sparkles more than any other!
  • Symmetry: Perfectly balanced, universally flattering shape.
  • Classic Appeal: Timeless, yet trendy.
  • Resale Value: In demand, so it holds the value.

Cons:

  • Higher Cost per Carat: Because they’re in high demand and more rough diamonds are lost in the cutting process.
  • Commonplace: If you're looking for something unique, round might feel too conventional.

The Oval: Grace with a Twist

Subtle yet powerful, oval diamonds can be seen as elongated versions of the classic round-cut, offering similar sparkle, but with a modern, fresh silhouette. The elongated shape of the diamond flatters almost everyone, creating an illusion of longer fingers. Not just that, it also creates the illusion of a larger stone without adding those extra carats, making it an excellent choice.

In short, oval diamonds are the perfect blend of classic beauty and modern sophistication. With brilliant faceting similar to the round cut, oval diamonds deliver exceptional sparkle making them a favourite for those who love elegance with a twist

Pros:

  • Illusion of Size: Appears larger than a round diamond of the same carat weight.
  • Elegant and Slimming: Flatters almost everyone
  • Unique Yet Timeless: A fresh take on the round cut.
  • Better Value: Often costs less than round diamonds of similar quality.

Cons:

  • Bow-Tie Effect: If the cut isn't perfectly done, a dark area can appear across the center.
  • Less Symmetry: More variation in length-to-width ratios

If brilliance is what you’re after, the Lab Grown Round Cut Diamond stands in a league of its own. The mathematically optimized arrangements of the facets are perfect for light reflection, creating unmatched sparkle. 

A well-cut Oval Lab Grown Diamond, on the other hand, delivers exceptional fire and brilliance. As the oval cut reflects light differently, it appears softer and more romantic, giving it a dreamy, glowing effect.

Style and Setting Considerations

Both shapes pair beautifully with a wide variety of settings, but the design direction may differ:

  • Round Diamonds lend themselves to timeless designs like solitaires, three-stone rings, and vintage-style halos.
  • Oval Diamonds shine in both minimalist and dramatic settings - think hidden halos, east-west orientations, or asymmetrical bands.

If you’re going for maximum tradition, a Round Diamond in a Solitaire Setting is unbeatable. But if you want a bit of flair, an Oval Diamond in a delicate Rose Gold Band Setting or with Side Stones can feel both bold and romantic.

Personality Match

The selection of shape also depends on what matches your vibe the most.

  • Round diamond: You appreciate tradition, elegance, and consistency. You’re drawn to timeless things, classy shoes, string quartets, and black coffee.
  • Oval diamond: You love subtle uniqueness and effortless style. You’re the kind of person who wears a white shirt with bold earrings or mixes vintage with modern.

The beauty of choosing a ring lies in the reflection of you - your style, your story, your individuality. There’s no wrong choice, only a meaningful one.

Price and Value

One practical consideration is pricing. Round diamonds are typically the most expensive per carat, because more rough diamond is lost during the cutting process. Ovals, on the other hand, offer better spread (surface area) and generally cost less per carat, making them a smart choice if you're looking to maximize your budget.

In terms of long-term value, round diamonds have historically held resale value better simply because of demand. However, with the rising popularity of unique shapes and lab-grown diamonds, this gap is slowly closing.

Final Thoughts

Choosing between a Round and Oval Diamond is like choosing between classic and contemporary. One offers a storied history of elegance and unmatched sparkle, while the other brings individuality, grace, and a touch of modern sophistication.

The most important thing is that your ring feels like you. Whether that means a timeless round solitaire or an oval diamond set east-west with hidden details, your choice should be something you’ll still love decades from now, not because it followed a trend, but because it tells your story.

So take your time, try on both, and let your heart, and hand, decide.
