Diamonds are timeless, but the trends surrounding diamond rings continue to evolve year after year. Whether you're in the market for an engagement ring or simply love keeping up with jewelry fashion, knowing the latest trends can help you choose a diamond ring that is both stylish and on-point. 

In 2025, diamond ring designs are blending classic elegance with contemporary flair, offering a wide variety of options to suit any taste. Here are the top 10 diamond ring trends you should watch for in 2025.

1. Lab-Grown Diamonds Take Center Stage

Lab-grown diamonds have been gaining popularity over the past few years, and in 2025, they’re set to dominate the market even more. These diamonds are chemically identical to natural diamonds but are created in a lab using advanced technology.

Why They’re Trending

Lab-grown diamonds offer a more affordable alternative to natural diamonds without sacrificing quality. They’re also considered more sustainable, as their production has a lower environmental impact. With growing awareness of ethical and environmental concerns, many consumers are turning to lab-grown diamonds for their engagement rings and fine jewelry.

What to Look For

When choosing a lab-grown diamond, look for reputable retailers who offer GIA or IGI certifications to ensure the quality and authenticity of the stone. Many jewelers also offer customization options for lab-grown diamonds, allowing you to choose the cut, color, and carat weight of your ring.

2. Sustainable and Ethical Sourcing

As consumers become more conscious of the environmental and social impact of their purchases, ethical sourcing is a major trend in 2025. More and more jewelry brands are committed to ensuring their diamonds are responsibly sourced.

Why It’s Trending

People are increasingly prioritizing sustainability in their purchases, and diamonds are no exception. The rise of ethical diamond mining and sustainable practices in jewelry production ensures that your purchase supports fair labor practices and reduces environmental harm.

What to Look For

Look for certifications like Kimberley Process Certification (KPC) or Fairmined, which ensure that the diamonds are sourced responsibly. Some jewelers also offer a "traceability" option, allowing you to trace the origin of the diamond in your ring.

3. Vintage-Inspired Diamond Rings

Vintage-inspired designs have been steadily gaining traction, and in 2025, this trend will continue to shine. These designs take inspiration from the past, particularly the Art Deco, Victorian, and Edwardian eras, and incorporate intricate details like milgrain edges, filigree patterns, and vintage cuts.

Why It’s Trending

Vintage styles are prized for their romantic and timeless appeal. Many couples today are seeking something unique, and vintage-inspired rings offer a personal touch that modern designs sometimes lack. Additionally, these styles often feature intricate craftsmanship that stands out from mass-produced, contemporary designs.

What to Look For

Look for rings with antique-inspired cuts such as the Old European Cut or Rose Cut, as these have a softer, more romantic sparkle compared to modern diamond cuts. Vintage-inspired settings with detailed engraving or milgrain edges will also add to the nostalgic charm of the piece.

4. Colored Diamonds and Gemstones

Colored diamonds are becoming increasingly popular in engagement rings and other fine jewelry. In addition to diamonds, colored gemstones like sapphires, emeralds, and rubies are also being used as center stones in diamond rings.

Why It’s Trending

Colored diamonds and gemstones offer a unique and personal touch to diamond rings. Many people are opting for these stones because they offer something different from the traditional colorless diamond, and they can also symbolize something personal, such as a birthstone or a favorite color.

What to Look For

In 2025, you’ll see diamonds in hues like fancy yellow, blue, and pink, as well as multi-colored diamonds, which have a stunning, rainbow-like effect. When selecting a colored gemstone, make sure it’s high-quality and properly set to showcase its brilliance.

5. Oval and Cushion-Cut Diamonds

While round diamonds are classic, oval and cushion-cut diamonds are gaining popularity due to their unique shape and elegant look. These cuts are versatile and work well in both vintage and modern settings.

Why They’re Trending

Oval diamonds are loved for their elongated shape, which makes the stone appear larger and more flattering on the finger. Cushion-cut diamonds, with their soft, rounded corners, offer a vintage feel and a softer sparkle compared to traditional cuts.

What to Look For

Oval and cushion-cut diamonds are excellent choices if you’re looking for something distinctive yet timeless. They pair well with a variety of settings, from simple solitaires to intricate halo designs. These cuts also tend to be more affordable than round diamonds of the same carat weight, making them a great value option.

6. Mixed Metals and Two-Tone Rings

Two-tone and mixed-metal rings are another major trend for 2025. These rings combine two or more metals, such as white gold, yellow gold, and rose gold, to create a unique and visually striking piece.

Why It’s Trending

Mixed-metal rings offer versatility and can complement any style or skin tone. They also allow for a more personalized touch, as you can mix and match metals to reflect your personal taste or lifestyle. These rings are especially popular for those who enjoy wearing multiple types of metal jewelry.

What to Look For

Look for designs where the diamond is set in one metal (usually white or platinum) while the band is made from another metal (like yellow or rose gold). This creates a beautiful contrast that enhances the diamond’s brilliance while adding warmth and sophistication to the overall look.

7. Stackable Diamond Rings

Stackable rings, or stacking bands, are an emerging trend in 2025, offering a modern and customizable way to wear diamond rings. These rings can be stacked on top of each other to create a layered effect or worn alone for a minimalist look.

Why They’re Trending

Stackable rings allow for flexibility and personalization. You can add or remove rings to create different looks, making it easy to change up your style based on your mood or outfit. Plus, stackable rings can represent different milestones, such as anniversaries, births, or other significant events.

What to Look For

Look for delicate, thin diamond bands that are designed to stack seamlessly. These can be paired with a solitaire engagement ring or worn on their own for a more modern, chic look. Stackable diamond rings are also great for mixing metals, allowing you to create a custom, personal style.

8. Alternative Diamond Cuts (Trilliant, Radiant, and Pear)

In 2025, more couples are stepping away from the traditional round cut and embracing alternative diamond cuts like trilliant, radiant, and pear-shaped diamonds. These cuts offer unique shapes that stand out while still showcasing the diamond’s brilliance.

Why They’re Trending

Alternative cuts are becoming more popular as people seek distinctive, non-traditional options for their engagement rings. These cuts offer a modern, edgy look while maintaining the same sparkle and elegance as more conventional cuts.

What to Look For

Trilliant and radiant cuts offer angular, geometric designs that provide a bold and contemporary aesthetic. Pear-shaped diamonds, with their teardrop shape, combine a traditional look with a touch of modernity. These cuts are perfect for those who want to make a statement with their engagement ring.

9. Non-Diamond Center Stones

As an alternative to traditional diamonds, many couples are opting for non-diamond center stones, such as moissanite, sapphire, and other precious gemstones. These stones are becoming increasingly popular in 2025 for engagement rings and other fine jewelry.

Why They’re Trending

Non-diamond stones like moissanite offer similar brilliance to diamonds but are much more affordable. Sapphires and other gemstones provide a pop of color and are symbolic for many people, with sapphires often representing loyalty and fidelity.

What to Look For

If you’re considering a non-diamond center stone, look for high-quality gemstones that are durable enough for daily wear. Moissanite is a popular alternative to diamonds because of its incredible sparkle, while sapphires are known for their rich blue color and hardness.

10. Custom and Personalized Designs

Custom-designed diamond rings are a growing trend in 2025, as more couples seek rings that reflect their unique love story. Custom rings allow for a high level of personalization, from the choice of stones to the setting and band design.

Why They’re Trending

Custom rings offer a way to create a one-of-a-kind piece that holds special meaning. Whether you’re incorporating a family heirloom diamond or designing a ring that reflects a personal aesthetic, a custom diamond ring is the ultimate in personalization.

What to Look For

When opting for a custom-designed ring, work closely with a jeweler who specializes in custom designs. Share your vision and be open to their advice on metal types, stone shapes, and settings. A custom ring ensures that you’ll have something truly unique to cherish for years to come.

As we head into 2025, diamond rings continue to evolve, blending timeless beauty with modern innovation. Whether you’re drawn to sustainable diamonds, vintage-inspired designs, or alternative diamond cuts, there’s something for every taste and style in the current jewelry landscape.
