Engagement rings are timeless symbols of love, and the centerpiece of any ring is, of course, the diamond. While the classic round brilliant cut has long dominated the market, evolving trends and personal preferences are reshaping the landscape of diamond shapes.
As we move into 2025, brides and grooms are leaning toward unique, eye-catching cuts that reflect individuality and modern aesthetics. Whether you’re shopping for an engagement ring or simply love keeping up with jewelry trends, this guide explores the most popular diamond shapes for engagement rings in 2025—and why they’re stealing the spotlight.
1. The Timeless Favorite: Round Brilliant Cut
Why It’s Still #1 in 2025
The round brilliant cut remains the most popular diamond shape, and for good reason. Its 58 precisely cut facets maximize sparkle, making it the ultimate choice for those who want unmatched brilliance.
- Pros: Unrivaled sparkle, versatile setting options, universally flattering.
- Cons: Higher price per carat due to cutting waste.
Despite the rise of fancy shapes, the round diamond continues to dominate engagement ring trends because of its classic elegance and light performance.
2. The Modern Favorite: Oval Cut
Why It’s So Popular in 2025
The oval cut diamond has surged in popularity over the last few years, and it’s not slowing down in 2025. Its elongated shape creates an illusion of longer, slimmer fingers, making it a favorite among brides who love a flattering and elegant look.
- Pros: Elongates the finger, appears larger than a round of the same carat weight, vintage yet modern appeal.
- Cons: May show a “bow-tie” effect (a dark area in the center) if not cut well.
Celebrities like Hailey Bieber and Blake Lively have popularized this shape, making it a top trend for 2025 engagement rings.
3. The Bold & Geometric: Princess Cut
Why It’s a Classic Choice
The princess cut is the second most popular diamond shape after round brilliant. Its sharp corners and square shape offer a contemporary yet timeless look, perfect for those who love clean lines and modern symmetry.
- Pros: Excellent sparkle, more affordable than round diamonds, works well in solitaire and halo settings.
- Cons: Prone to chipping at the corners (requires a protective setting).
In 2025, we’re seeing more mixed-cut princess diamonds with unique faceting patterns for added brilliance.
4. The Vintage Revival: Emerald Cut
Why It’s Trending in 2025
The emerald cut is all about understated elegance. With its step-cut facets and rectangular shape, this diamond exudes old Hollywood glamour—think Grace Kelly and Amal Clooney.
- Pros: Shows exceptional clarity, offers a sleek, sophisticated look, appears larger due to its table (flat top).
- Cons: Less sparkle than brilliant cuts, inclusions are more visible.
In 2025, emerald cuts are being set in East-West orientations and art deco-inspired designs, making them a favorite for minimalist and vintage lovers.
5. The Romantic Choice: Pear Cut (Tear Drop)
Why It’s Gaining Popularity
The pear cut—a hybrid of round and marquise shapes—is making waves in 2025 for its unique, romantic silhouette. This shape is perfect for those who want something unconventional yet timeless.
- Pros: Elongates the finger, versatile (can be set with point up or down), eye-catching.
- Cons: Pointed tip is vulnerable to chipping, requires a well-balanced cut.
Pear-shaped diamonds are being embraced in modern solitaires, halo settings, and even asymmetrical designs, making them a standout trend for 2025.
6. The Edgy & Unique: Marquise Cut
Why It’s a Showstopper in 2025
The marquise cut (also called the “navette” cut) is one of the most dramatic and elongating diamond shapes. Its football-like shape maximizes carat weight, making it appear larger than other cuts.
- Pros: Creates the illusion of longer fingers, bold and regal look, great for vintage-inspired rings.
- Cons: Pointed ends need protection, bow-tie effect possible if poorly cut.
In 2025, marquise diamonds are being set in floating halos, three-stone rings, and even as accent stones for a bold, statement look.
7. The Soft & Feminine: Cushion Cut
Why It’s a Timeless Favorite
The cushion cut—a mix between a round and square shape—has a soft, romantic appeal that’s perfect for vintage and modern styles alike.
- Pros: Vintage charm, excellent brilliance (especially in “crushed ice” faceting), hides inclusions well.
- Cons: Can appear smaller than other shapes of the same carat weight.
In 2025, modified cushion cuts with extra facets are trending, offering even more sparkle.
8. The Contemporary Favorite: Radiant Cut
Why It’s a Brilliant Choice
The radiant cut combines the elegance of an emerald cut with the sparkle of a round brilliant. Its cropped corners and brilliant faceting make it a versatile and dazzling option.
- Pros: High brilliance, hides inclusions well, works in square or rectangular ratios.
- Cons: Less “classic” than round or princess cuts.
Radiant cuts are increasingly popular in colorless and fancy-colored diamonds, making them a top 2025 trend.
9. The Minimalist’s Dream: Asscher Cut
Why It’s a Sleek Choice
The Asscher cut is like the emerald cut’s square cousin, with deep step cuts and a mesmerizing hall-of-mirrors effect.
- Pros: Art deco appeal, unique and rare, excellent symmetry.
- Cons: Shows inclusions easily, less sparkle than brilliant cuts.
In 2025, Asscher cuts are being set in bezel and three-stone settings for a modern vintage look.
10. The Rising Star: Hexagonal & Other Fancy Shapes
Why They’re the Future
Beyond traditional shapes, hexagonal, kite, and other custom cuts are gaining traction in 2025. These ultra-unique shapes appeal to those who want a one-of-a-kind ring.
- Pros: Completely unique, artistic, conversation-starting.
- Cons: Harder to find, may require custom settings.
Designers are experimenting with asymmetrical and geometric shapes, making these diamonds a bold trend for 2025.
