Choosing the right diamond shape for an engagement ring is more than just a matter of taste. It is a decision that reflects personal style, fashion influences and sometimes even deeper trends moving through society. As a jeweler who has helped countless couples select their perfect ring, I have witnessed firsthand how these preferences evolve from year to year. Walking clients through the process, I always notice how quickly opinions can shift, especially when a certain celebrity flashes a new style on social media or a designer launches a fresh collection.
Over the past decade, I have seen the classics hold their ground, but every so often, a surprising favorite rises to the top and captures everyone’s imagination. Some couples arrive at my shop already set on a shape they have admired for years. Others only discover what truly speaks to them when they see the options side by side under the store lights. There is something genuinely exciting about that moment of recognition when someone realizes which diamond shape suits them best.
The shape of a diamond does more than determine how a ring looks. It can influence how large or brilliant the stone appears, how much you will pay for it and even how easy it is to find a matching wedding band. Some shapes flatter particular finger types, while others feel timeless or even daringly modern. In 2025, the landscape of engagement ring design is as diverse as ever, with old favorites and bold newcomers competing for attention.
If you are curious about which diamond shapes are capturing hearts this year, you are not alone. Trends are shifting quickly, with influences coming from all directions: celebrity engagements, viral TikTok videos and the growing world of lab-grown diamonds. As a jeweler, I enjoy spotting these patterns early and helping people find a ring that feels right for their story. In the following guide, I will share what I have observed about 2025’s most popular diamond shapes and the factors that are driving these choices. Whether you are about to propose or simply love the artistry of fine jewelry, this year’s trends have something for everyone.
Introduction: What’s Hot in 2025 for Diamond Shapes
If you have been browsing engagement rings this year, you have probably noticed a refreshing blend of classic favorites and bold new shapes capturing the spotlight. In 2025, the world of diamond shapes is more dynamic than ever. Customers are mixing tradition with personal flair and the result is a fascinating array of choices both in-store and online.
To give you a quick overview of which shapes are winning hearts this year, here is a look at the estimated popularity of each diamond shape in 2025, based on recent industry reports and what I have seen in my own shop:
| Rank | Diamond Shape | Estimated % of Sales | Why It’s Trending |
|---|---|---|---|
| 1 | Round Brilliant | 38% | Timeless, maximum sparkle, fits any style |
| 2 | Oval | 21% | Elegant, elongates finger, strong social buzz |
| 3 | Cushion | 11% | Vintage feel, soft corners, strong fire |
| 4 | Emerald | 9% | Sophisticated, clean lines, Art Deco vibes |
| 5 | Pear | 7% | Unique, vintage-modern blend, versatile |
| 6 | Radiant | 5% | Brilliant cut, rectangular shape, modern |
| 7 | Princess | 4% | Geometric, contemporary, great sparkle |
| 8 | Marquise | 3% | Vintage, dramatic, finger-flattering |
| 9 | Heart | 1% | Romantic, symbolic, niche appeal |
| 10 | Asscher/Other | 1% | Niche, antique lovers, statement seekers |
Round brilliant diamonds are still the backbone of engagement ring trends. They remain popular for their timeless sparkle and universal appeal. Yet, there is no denying that today’s couples are becoming increasingly adventurous. Fancy shapes, like ovals, cushions and elongated emerald cuts, are climbing the charts, making a strong statement on social media feeds and celebrity ring fingers alike.
One of the biggest changes I have seen this year is the willingness of shoppers to look beyond tradition. Oval and pear shapes are everywhere, admired for their finger-flattering profiles and modern elegance. Emerald and radiant cuts, once considered niche or even vintage, have suddenly become favorites among those who want something refined and unique. Even marquise and heart shapes are having a quiet resurgence, often chosen by people who want their ring to stand out in a crowd.
The influence of lab-grown diamonds has also added fuel to this fire. With more options at every price point, couples can now focus on getting the shape and size they truly want without feeling limited by budget. Designers are responding with creative settings and mixes of shapes in a single ring, allowing for personal expression like never before.
In short, the definition of “popular” has broadened in 2025. There is truly a diamond shape for every personality and style. In the following sections, I will break down which shapes are leading the pack and explain why each one is finding its place on so many hands this year.
The Top Diamond Shapes for Engagement Rings in 2025
Every year brings a subtle shift in what couples gravitate toward, but 2025 feels especially vibrant when it comes to diamond shapes. Here are the most sought-after shapes in my showcases and consultations this year, along with what’s driving their popularity:
1. Round Brilliant
Round diamonds are still the anchor of the market. Their unmatched sparkle and symmetry make them an easy favorite for those who want something classic and universally flattering. They work beautifully in almost any setting, from traditional solitaires to modern halos. The round cut is also the most forgiving of inclusions and color, which gives buyers a little more flexibility in their choices.
2. Oval
If there’s one shape that keeps rising, it’s the oval. Ovals have taken the engagement ring world by storm because they offer an elegant twist on the round, elongate the finger, and often appear larger per carat. Social media, especially Instagram and Pinterest, has played a huge role in making oval shapes the go-to for trendsetters and brides seeking a modern, yet romantic, look.
3. Cushion
Cushion-cut diamonds combine a vintage feel with a plush, soft appearance. Their pillow-like silhouette and gentle corners appeal to those who want a touch of old-world glamour without going full antique. The cushion’s ability to showcase fire (those flashes of color) makes it especially appealing under different lighting.
4. Emerald
Emerald cuts have become the sophisticated choice for buyers looking for clean lines and understated elegance. With their hall-of-mirrors effect and long, dramatic facets, emerald diamonds appeal to those with minimalist or Art Deco tastes. This year, I have seen more emerald cuts paired with thin, sleek bands for a refined, contemporary statement.
5. Radiant
Radiant cuts are bridging the gap between emerald and round, offering brilliance with a rectangular (or sometimes square) shape. Their lively sparkle and modern edge are particularly popular among younger buyers who want something different but don’t want to sacrifice shine.
6. Pear
Pear-shaped diamonds continue to gain fans for their distinctive teardrop silhouette. They offer both vintage charm and a fresh, bold personality. Pears are also highly versatile, working well in solitaire, halo and three-stone settings, and can be worn pointing up or down depending on the wearer’s style.
7. Marquise
The marquise is enjoying a subtle revival this year. Its elongated, pointed shape can make fingers look longer and more slender. It’s often picked by those who love vintage-inspired designs or simply want a diamond shape that stands out in a crowd.
8. Princess
Princess-cut diamonds have a crisp, geometric appeal. They remain a solid favorite, especially for those who want maximum sparkle in a square shape. The princess cut is often chosen for contemporary settings and adds a modern edge to the traditional engagement ring.
Honorable Mentions:
Heart shapes, Asscher cuts, and even old mine cuts are finding niche followings, often among couples seeking something truly unique or symbolic.
In summary, 2025 is a year of diversity and self-expression. Whether clients choose a time-honored round or a bold pear or marquise, the emphasis is on finding a shape that fits their story and style. The market is ready for every taste, and there’s a sense of freedom that makes this an exciting year to choose an engagement ring.
What Drives the Popularity of Certain Shapes?
The popularity of diamond shapes is influenced by a combination of factors, many of which change with time and cultural trends. Celebrities play a big role: when someone famous is seen with a particular engagement ring, that style can quickly become the “it” shape. For example, oval and pear-shaped diamonds have both enjoyed a surge after making appearances on high-profile hands: Hailey Bieber’s oval-cut engagement ring from Justin Bieber set off a wave of oval popularity, while Ariana Grande and Sophie Turner both showcased stunning pear-shaped rings that drew fresh attention to that elegant cut.
At the same time, fashion cycles always have their effect. While the round brilliant diamond has held the crown for decades, shapes like the emerald and cushion have moved in and out of favor as vintage-inspired and art-deco styles return to the spotlight. Visual appeal also matters, as certain shapes are engineered to maximize sparkle, while others, such as the emerald or asscher cut, offer a more subtle, mirror-like elegance that attracts buyers looking for something refined and understated.
Some shoppers are drawn to shapes that provide more finger coverage, like ovals or marquise cuts, since these make a diamond appear larger for its carat weight, which is a strong selling point for those wanting impressive presence on the hand. The design of ring settings can also drive shape preferences, as trending setting styles often pair best with certain cuts.
Lastly, regional and cultural influences play their part. While round diamonds dominate in some markets, princess and other fancy shapes have devoted followings elsewhere. Ultimately, the popularity of a diamond shape comes down to a blend of cultural moments, personal style and the visual impact that captures people’s attention at just the right time.
How Shape Affects Sparkle and Cost
The shape of a diamond isn’t just about personal style, it has a real impact on both how much the stone sparkles and how much you can expect to pay. Each diamond shape interacts with light differently, creating its own style of brilliance and fire. The classic round brilliant cut is famous for its unmatched sparkle, thanks to the way it’s engineered to reflect light from every angle. If maximum dazzle is your goal, round is the undisputed champ.
Other shapes, sometimes called “fancy shapes,” have their own unique personalities. For example, princess cuts are known for sharp angles and lots of sparkle, while emerald and Asscher cuts show off more subtle flashes of light with broad, mirror-like facets—what experts call a “hall of mirrors” effect. Oval, pear, and marquise shapes tend to appear larger for their carat weight and can also give plenty of sparkle, but with a softer, elongated look.
When it comes to price, shape makes a surprising difference. Round diamonds are usually the most expensive per carat because they require more of the rough stone to be cut away and there’s more demand. Fancy shapes like oval, cushion, pear and emerald often cost less for the same carat weight, simply because less of the original diamond is lost in the cutting process and they’re less in demand. This means you might get a noticeably larger-looking diamond for your budget if you’re open to shapes other than round.
Shape can also play a role in how a diamond hides or highlights inclusions and color. For example, step cuts like emerald and Asscher are less forgiving, so higher clarity and color grades are more important. On the other hand, brilliant cuts (round, oval, pear, cushion) tend to hide imperfections and warmth better, allowing you to prioritize size or cut without sacrificing overall appearance.
In short, choosing the right diamond shape isn’t just about aesthetics, it’s about maximizing both beauty and value based on your priorities.
