1. Lab-Grown Oval Diamonds Take Center Stage

One of the biggest trends in 2025 is the rise of lab-grown oval diamonds. With sustainability becoming a top priority, couples are leaning toward diamonds that have a lower environmental footprint while still maintaining the brilliance and quality of mined stones.

Lab-grown diamonds are chemically identical to natural ones, yet they are far more affordable. This allows buyers to opt for larger carat sizes or higher-quality stones without exceeding their budget. Oval shapes, in particular, benefit from this trend because the elongated cut appears even bigger when paired with a lab-grown option.

Why it’s trending:

• Eco-friendly and conflict-free
  

• More affordable pricing for luxury looks
  

• Ideal for socially conscious buyers

2. Hidden Halo Settings

The hidden halo setting is becoming increasingly popular in 2025, especially for oval diamond rings. Unlike traditional halo rings, where small diamonds surround the center stone, the hidden halo tucks away a circle of diamonds beneath the main oval.

This design adds extra sparkle when viewed from the side without overwhelming the simplicity of the oval cut. It’s the perfect balance between understated elegance and modern glamor.

Best for: Brides who want sparkle but still value minimalism.

3. East-West Oval Diamond Rings

Traditional oval diamonds are set vertically, but the East-West setting—where the oval lies horizontally—is trending this year. It’s a contemporary take that makes the ring feel bold, unique, and fashion-forward.

This design is gaining traction among couples who want something that breaks away from conventional engagement ring styles. It works beautifully with solitaire designs or sleek bands, making it a versatile choice for modern jewelry lovers.

4. Two-Stone Oval Rings

The two-stone engagement ring trend, also known as “Toi et Moi” (French for “you and me”), has exploded in 2025. This romantic style features two stones set side by side, often an oval paired with another shape like a pear or emerald cut.

This symbolizes the union of two individuals, making it a deeply meaningful design. Celebrities have helped popularize this style, and it’s expected to remain a top choice for couples who value symbolism in their jewelry.

5. Mixed Metal Bands

Gone are the days when buyers stuck to only platinum or gold. In 2025, mixed metal bands are making waves in the oval diamond ring market. Combining white gold with yellow or rose gold allows for a personalized, modern look.

Not only does this create visual contrast, but it also makes the ring more versatile to wear with other jewelry pieces. Oval diamonds, with their elongated and symmetrical cut, look especially stunning against two-tone designs.

6. Vintage-Inspired Oval Diamond Rings

Vintage jewelry styles are experiencing a revival, and oval diamonds fit perfectly into this movement. In 2025, expect to see more Art Deco and Victorian-inspired settings with intricate details like milgrain edges, filigree, and floral motifs.

These rings are ideal for buyers who want their jewelry to feel timeless yet distinctive. Paired with an oval diamond, the vintage setting enhances the old-world charm while keeping the design elegant.

7. Thin and Delicate Bands

Minimalism is trending across fashion, and jewelry is no exception. Many couples in 2025 are opting for slim, delicate bands that highlight the beauty of the oval stone without distraction.

A thinner band makes the center diamond appear larger, and the oval shape complements the sleek look perfectly. This style is popular among those who prefer understated elegance and long-term wearability.

8. Bezel Settings for Modern Elegance

The bezel setting—where the diamond is encased in a thin rim of metal—is returning in popularity, especially for oval diamonds. Not only does it offer a sleek, contemporary aesthetic, but it also provides excellent protection for the diamond.

This makes bezel-set oval rings a practical choice for active lifestyles without compromising on beauty. Many jewelers are offering both minimalist and bold bezel designs in 2025.

9. Colored Oval Diamonds

2025 is the year of bold personalization, and colored diamonds are stepping into the spotlight. Oval cuts in shades like champagne, yellow, or even rare pink are trending among buyers who want something truly one-of-a-kind.

These colorful stones, when set in simple or vintage bands, create a statement piece that stands out from traditional white diamonds. Paired with rose gold or yellow gold, colored oval diamonds exude warmth and individuality.

10. Sustainable and Ethical Jewelry Practices

Beyond just lab-grown diamonds, consumers in 2025 are demanding more transparency from jewelers. Oval diamond rings that come with certifications of ethical sourcing, recycled metals, and eco-conscious craftsmanship are becoming top priorities.

Retailers like C6 Diamonds are responding to this demand by offering collections that prioritize sustainability without sacrificing luxury. For buyers, this means peace of mind while still enjoying exquisite jewelry.

11. Oval Diamond Rings with Side Stones

While solitaire oval rings remain timeless, side-stone designs are trending in 2025. Small diamonds or gemstones set along the band add brilliance and detail, enhancing the center oval without overpowering it.

Popular variations include pavé bands, baguette side stones, or tapered diamonds leading up to the oval. This design is perfect for buyers who love added sparkle.

12. Customization and Personalization

More couples in 2025 are moving toward custom oval diamond rings. Instead of buying pre-designed styles, they want jewelry that reflects their story and preferences. From engraving initials to adding hidden birthstones in the band, customization adds sentimental value.

C6 Diamonds specializes in creating personalized oval diamond rings that capture individual styles while keeping up with current design trends.

Why Oval Diamond Rings Are the 2025 Favorite

Oval diamonds are not only timeless but also adaptable to modern tastes. Their ability to appear larger than round diamonds of the same carat weight makes them a popular choice for couples seeking maximum brilliance at a better value.

Additionally, their elongated shape creates a slimming effect on fingers, making them universally flattering. With the added emphasis on sustainability, customization, and bold designs, oval diamond rings are positioned as the go-to engagement ring choice in 2025.

Conclusion

Oval diamond rings are more than just a trend—they are a perfect blend of timeless beauty and modern innovation. From hidden halos to east-west settings and sustainable sourcing, the design directions of 2025 showcase how versatile and personal this diamond shape can be.
