If you’ve taken a stroll through the jewelry districts of New York, Chicago, or L.A. lately, you’ll notice that the American “dream ring” is evolving. While the diamond remains the ultimate symbol of love and commitment in the U.S., the way that diamond looks is changing faster than ever.

In 2026, the U.S. market is a fascinating blend of high-tech innovation and vintage nostalgia. Whether you’re shopping for an engagement or an investment, here is your definitive guide to the top-selling diamond styles dominating the American market today.

1. The Round Brilliant: The Undisputed King

Even with all the new trends, the Round Brilliant remains the #1 best-seller in the United States. It consistently accounts for over 60% of all diamond sales nationwide.

• Why it sells: It’s all about the “fire.” With 58 facets, it is engineered to reflect the maximum amount of light.
• The 2026 Twist: American buyers are moving away from traditional “dainty” prongs and opting for Bezel Settings or Chunky Yellow Gold Bands to give this classic stone a modern, “cool-girl” edge.

2. The Oval Cut: The Social Media Sensation

If there is one shape that defines the 2020s in America, it is the Oval Cut. It currently holds the title of the most popular “Fancy Shape” in the U.S.

• The Appeal: The elongated shape creates an optical illusion, making the diamond appear larger than a round stone of the same weight. It also has a slimming effect on the fingers—a feature that makes it a favorite for “hand selfies” on Instagram and TikTok.
• Celebrity Influence: Followed by the “Hailey Bieber effect,” the oval has become the go-to for American fashionistas seeking a blend of elegance and modern flair.

3. The Emerald Cut: Embracing “Quiet Luxury”

The “Quiet Luxury” or “Old Money” aesthetic has taken the U.S. by storm, and nothing fits this vibe better than the Emerald Cut.

• The Aesthetic: Unlike the glittery sparkle of other cuts, the Emerald cut offers a “Hall of Mirrors” effect. It values clarity and sleek, architectural lines over raw brilliance.
• Buyer Behavior: This style is particularly dominant in the luxury markets of the Northeast (NYC, Boston, DC), where sophisticated, understated elegance is the priority.

4. The Radiant and Elongated Cushion: The Best of Both Worlds

For many American buyers, the choice is between a rectangular shape and a brilliant sparkle. The Radiant Cut and Elongated Cushion provide the perfect solution.

• The Hybrid: These cuts offer the silhouette of an Emerald cut but with the “crushed ice” sparkle of a Round Brilliant.
• Lab-Grown Influence: The boom in Lab-Grown Diamonds in the U.S. has made these cuts even more popular, as buyers can now afford 4 or 5-carat stones that truly make a statement.

Key Trends Driving the U.S. Market in 2026

1. The Lab-Grown Revolution

Over half of the engagement rings sold in the U.S. this year feature Lab-Grown Diamonds. This shift has allowed Americans to prioritize size and cut quality over “natural” origin, leading to a surge in larger, high-quality fancy shapes.

2. East-West Settings

A major trend in 2026 is the East-West setting, where elongated stones (like Ovals, Marquise, or Emeralds) are set horizontally across the band rather than vertically. It’s a favorite for the buyer who wants to break away from tradition.

3. Yellow Gold is Back

After decades of Platinum and White Gold dominance, 18k Yellow Gold is once again the most requested metal in U.S. jewelry stores, providing a warm contrast to the bright white of a high-quality diamond.

Final Verdict

The U.S. diamond market is no longer about following a single rulebook. While the Round Brilliant is the safe, sparkling investment, the Oval and Emerald cuts represent the new American era of individuality and “Quiet Luxury.”

Which cut are you dreaming of? Are you a fan of the classic Round or the modern Oval? Let us know in the comments below!

If you look at the engagement rings flashing across New York City or Los Angeles this year, you’ll notice something interesting: the American taste in diamonds is shifting. While the “classic” look still holds a special place in the hearts of many, a new set of shapes and styles has taken over the throne.

But have you ever wondered why? In the United States, a diamond isn’t just a stone; it’s a status symbol, a fashion statement, and a reflection of personal values.

Here is why these specific diamond styles are dominating the U.S. jewelry market in 2026.

---

1. The Pursuit of “Visual Carat Weight”

Americans love a “big” look. This cultural preference is the primary reason why elongated cuts like Oval, Emerald, and Pear have seen a massive surge in sales.

• The Optical Illusion: Because these shapes are elongated, they occupy more “real estate” on the finger. An oval diamond can look up to 15-20% larger than a round diamond of the same carat weight.
• The Slimming Effect: These cuts act like “vertical stripes” for the hand, making the wearer’s fingers look longer and more slender—a look that is highly coveted in the U.S.

2. The “Hailey Bieber” & Celebrity Ripple Effect

In the U.S. market, celebrity influence isn’t just a trend; it’s a market mover.

• Trend-Setting: When a major A-lister gets engaged with an Oval or an East-West set Radiant cut, search volume for those specific styles on sites like Blue Nile or Tiffany & Co. spikes within hours.
• Modern Icons: The current dominance of the Oval cut can be traced directly back to the “Bieber effect,” which transformed a niche shape into the most requested fancy cut in America.

3. The Rise of “Quiet Luxury” and Step Cuts

The “Quiet Luxury” (or Old Money) aesthetic has hit the U.S. jewelry market hard in 2026. This has led to a massive comeback for Emerald and Asscher cuts.

• Understated Elegance: Unlike the “disco ball” sparkle of a Round Brilliant, the Emerald cut offers a sophisticated “hall of mirrors” effect.
• The Message: It signals a wearer who values clarity and quality over raw, flashy brilliance. It’s a “if you know, you know” type of luxury that resonates with the American upper-middle class.

4. The Lab-Grown Revolution

You cannot talk about the U.S. diamond market without mentioning Lab-Grown Diamonds (LGDs). This technology has completely changed which styles dominate.

• Affordability of Fancy Shapes: Historically, fancy cuts like Heart or Marquise were expensive because they were difficult to cut from natural rough stone. With lab-grown technology, these unique shapes are more accessible.
• Bigger is Now Possible: American buyers are now opting for 3-carat to 5-carat stones in Radiant or Cushion cuts because the price point of lab-grown diamonds allows them to get the “dream size” that was previously out of reach.

5. Individuality Over Tradition

Gen Z and Millennial buyers in the U.S. are moving away from “what their parents wore.” This has opened the door for Alternative Styles:

• Salt and Pepper Diamonds: For the edgy, bohemian buyer.
• Vintage Revival: A love for Old Mine Cuts that feel unique and one-of-a-kind.
• Bezel Settings: Moving away from traditional prongs to sleek, metal-wrapped edges that fit an active, modern American lifestyle.

Final Thoughts

The U.S. diamond market in 2026 is a beautiful contradiction. It’s a mix of a 100-year-old love for the Round Brilliant and a modern obsession with the “new and unique.” Whether it’s the influence of TikTok or the shift toward sustainable lab-grown stones, Americans are choosing diamonds that tell a specific story about who they are.

If you’ve been scrolling through Instagram or Pinterest lately, you’ve probably noticed that the American engagement ring scene is undergoing a massive transformation. The days of “one-size-fits-all” are long gone. In 2026, the United States jewelry market is all about individuality, bold silhouettes, and a fascinating mix of vintage charm and modern tech.

Whether you’re shopping for an engagement ring or just looking to upgrade your jewelry box, understanding the “it” shapes is crucial. Let’s dive into the most popular diamond cuts currently dominating the U.S. market!

1. The Round Brilliant: Still the King (But With a Twist)

The Round Brilliant Cut remains the most popular choice in the U.S., accounting for about 36% of sales in recent years. However, its massive lead is narrowing.

• The Trend: While the classic solitaire is still a hit, American buyers are now pairing round stones with chunky yellow gold bands or bezel settings for a more “quiet luxury” look.
• Why it lasts: It offers the most “fire” and sparkle of any shape, making it the safest investment for long-term value.

2. The Oval Cut: The “Celebrity” Favorite

If 2025 was the year of the Oval, 2026 is the year it became a classic. Inspired by stars like Hailey Bieber and Blake Lively, the Oval Cut is currently the #1 “fancy shape” in America.

• Why it’s trending: Its elongated shape makes the finger look slimmer and—here’s the best part—it often looks larger than a round diamond of the same carat weight.
• Market Insight: We are seeing a huge spike in East-West settings, where the oval is turned horizontally for a modern, edgy vibe.

3. The Emerald Cut: Sophistication & “Old Money” Aesthetic

The “Old Money” style has taken the U.S. by storm, and nothing screams “sophisticated” like an Emerald Cut.

• The Look: Known for its “hall-of-mirrors” effect, this step-cut diamond emphasizes clarity over raw sparkle.
• Buyer’s Tip: Because the flat surface (the table) is so clear, any imperfections are visible. U.S. buyers are currently prioritizing higher Clarity grades (VS1+) for this specific cut.

4. The Vintage Revival: Old Mine & Cushion Cuts

Thanks to high-profile celebrity engagements (yes, we’re looking at the “Taylor Swift effect”), Old Mine Cuts and Elongated Cushions are having a massive renaissance.

• The Vibe: These cuts have a romantic, pillow-like shape with soft edges. They feel “heirloom,” even if they were grown in a lab yesterday.
• Setting Trend: Most U.S. buyers are opting for vintage-inspired settings with milgrain detailing or sculptural metalwork to match these stones.

5. The Rising Stars: Radiant and Marquise

• Radiant Cut: For those who want the silhouette of an emerald cut but the sparkle of a round brilliant. It’s becoming the go-to for Lab-Grown enthusiasts who want a “big rock” look.
• Marquise Cut: Once considered “outdated,” the Marquise is back in 2026. It’s bold, unique, and offers the greatest surface area, making your diamond look massive.

Beyond the Cut: What Else Is Moving the U.S. Market?

It’s not just about the shape anymore. Two major factors are currently steering American buyer behavior:

1. The Lab-Grown Revolution: Over 50% of U.S. couples are now choosing lab-grown diamonds. This allows them to buy much larger stones (3+ carats) in premium cuts like Oval or Radiant without the 5-figure price tag.
2. Sustainability: “Ethically sourced” isn’t a buzzword; it’s a requirement. Buyers are demanding blockchain-traceable diamonds and recycled gold.

Final Verdict

If you want something timeless, go Round. If you want to be on-trend, the Oval or Elongated Cushion is your best bet. But if you want to make a statement of pure class, the Emerald Cut is the winner of 2026.

If you’ve ever walked into a jewelry boutique in New York or scrolled through Pinterest for engagement ring inspo, you know that a diamond isn’t just a diamond. The cut is the soul of the stone—it dictates how it sparkles, how it sits on your finger, and even how big it looks!

As we move through 2026, the US jewelry market is seeing a fascinating mix of “undisputed classics” and “modern rebels.” Whether you’re a soon-to-be-fiancé or a jewelry enthusiast, here is the ultimate breakdown of the most popular diamond cuts currently dominating the American market.

---

1. The Undisputed King: Round Brilliant Cut

Despite all the changing trends, the Round Brilliant Cut remains the gold standard. In fact, it still accounts for nearly 75% of all diamonds sold in the United States.

• Why it’s a favorite: It’s all about the physics! With 58 facets, it is mathematically engineered to reflect the maximum amount of light.
• The Vibe: Timeless, versatile, and high-octane sparkle.
• Pro Tip: Because of the high demand and the amount of “rough” diamond lost during cutting, this is usually the most expensive shape per carat.

2. The Modern Icon: Oval Cut

If 2024-2025 was the “year of the oval,” 2026 is the year it became a permanent staple. Thanks to celebrities like Hailey Bieber and Blake Lively, the Oval Cut is the top choice for those who want something trendy yet elegant.

• The “Magic” of Oval: Its elongated shape creates an optical illusion, making the diamond look larger than a round stone of the same carat weight. Plus, it has a slimming effect on the fingers!
• Market Insight: It’s currently the #1 “fancy shape” (any shape that isn’t round) in the US.

3. The “Quiet Luxury” Pick: Emerald Cut

With the rise of the “Old Money” and “Quiet Luxury” aesthetic, the Emerald Cut has seen a massive surge in the US luxury segment. Unlike the glittery sparkle of a round diamond, the emerald cut offers a “hall of mirrors” effect.

• Style Note: Its long, lean lines and step-cuts emphasize clarity over sparkle.
• Caveat: Because of its large open table (top surface), any inclusions (flaws) are easier to see. If you go for an Emerald cut, don’t skimp on the Clarity grade!

4. The Bold & Edgy: Radiant and Princess Cuts

For those who love a square or rectangular silhouette but don’t want to sacrifice the “big sparkle,” the Radiant Cut is winning hearts in 2026. It combines the elegant shape of an emerald cut with the brilliant faceting of a round diamond.

Meanwhile, the Princess Cut remains a solid choice for those who love clean, geometric lines and a modern, architectural feel.

5. The Vintage Revival: Cushion Cut

The Cushion Cut (often called the “pillow cut”) is the bridge between modern and vintage. With its rounded corners and soft edges, it’s been a top-tier choice for American brides who want a romantic, antique look.
