When it comes to selecting the best diamond shape for an engagement ring, every woman wants a cut that reflects her style, elegance, and personality. In 2025, the three most popular diamond cuts, Oval, Emerald, and Marquise, are taking center stage, each offering a unique aesthetic and timeless appeal. Whether you’re looking for a modern classic, vintage sophistication, or a bold statement, these trending diamond cuts for engagement rings are capturing hearts worldwide.

At VivuBijou, we specialize in custom-made jewelry, ensuring that your diamond isn’t just a gemstone but a personal expression of love and luxury. Let’s explore why these shapes are the top picks this year and which one might be the perfect match for you.

Why Diamond Cut Matters?

The diamond cut is more than just its shape; it determines how well the stone reflects light, its brilliance, and overall beauty. A well-cut diamond enhances sparkle, whereas a poorly cut one may appear dull. When choosing the best diamond shape for customised jewelry, it's essential to balance aesthetics with quality, ensuring your piece stands out.

The Trending Diamond Cuts of 2025

1. Oval Cut: The Modern Classic

The oval cut engagement ring trend continues to dominate in 2025, loved for its elegant, elongated shape and brilliant sparkle.

✔ Why is the oval diamond so popular?

• • It maximizes the perceived size of the diamond, making it appear larger than other cuts of the same carat weight.
  • Creates an illusion of longer, slender fingers.
  • Ideal for both vintage and modern ring settings.

✔ Best settings for oval diamonds: Solitaire, Halo, or Hidden Halo settings enhance their brilliance beautifully.

2. Emerald Cut: Timeless Sophistication

For those who prefer understated elegance, the emerald cut diamond is a top contender. Unlike other cuts, the emerald, oval, and marquise debate often comes down to brilliance versus refinement.

✔ Emerald cut diamond pros and cons:

• Pros: Offers a hall-of-mirrors effect with step-cut facets, exuding vintage charm.

• Cons: Less sparkle than brilliant cuts, but highlights clarity.

  • • Perfect for those who appreciate a minimalist, structured look.

    • Preferred by celebrities and royals for its timeless appeal.

✔ Best settings for emerald diamonds: Bezel or Three-Stone settings emphasize its elegant lines.

3. Marquise Cut: Unique and Eye-Catching

For the bold and unconventional, the marquise diamond ring styles offer a striking, elongated look that maximizes carat weight.

✔ Which diamond cut is best for an engagement ring in 2025?

• If you want uniqueness, the marquise is the answer.
• Its pointed ends create a regal, elongated silhouette.
• Known as the "navette cut," it dates back to the French royal courts.

✔ Best settings for marquise diamonds: East-West, Halo, or Vintage settings enhance their dramatic look.

How to Choose the Perfect Diamond Cut?

Choosing between oval vs emerald, vs marquise diamonds depends on personal style and finger shape:

✔ For a modern yet classic look: Go for an oval cut. ✔ For vintage sophistication: The emerald cut is the way to go. ✔ For a bold statement ring, the marquise cut steals the show.

Additionally, if you’re considering the best diamond shape for custom-made jewelry, opt for one that aligns with your lifestyle and personality.

Pairing Your Diamond Cut with the Right Setting

Selecting the right ring setting enhances the beauty of your diamond cut:

• Best settings for oval, emerald, and marquise diamonds: Halo, Solitaire, or Bezel settings for extra security and elegance.

• Classic vs modern diamond cuts: Oval is a blend of both, Emerald is classic, and Marquise leans towards vintage and bold aesthetics.

• Metal Choices: White gold, yellow gold, and platinum bring out the best in these shapes.

Final Thoughts: Which One Should You Choose?

The best diamond shape for customised jewelry depends on what resonates with your personal style. Whether it’s the brilliance of an oval cut, the structured elegance of an emerald cut, or the regal charm of a marquise cut, each diamond shape tells its own story.
