Radiant-Cut Diamonds: The Ultimate Guide

The radiant-cut diamond has seen a surge in popularity over the past 8–10 years, thanks to its elongated shape and exceptional brilliance. Combining the best features of the emerald and round brilliant cuts, the radiant-cut diamond offers maximum sparkle with a modern, elegant appeal. If you're considering a radiant-cut engagement ring or want to learn more about this dazzling shape, this guide covers everything you need to know.

 

What is a Radiant-Cut Diamond?

A radiant-cut diamond is a rectangular or square-shaped diamond with brilliant-cut facets, designed to maximize light reflection and sparkle. Unlike emerald-cut diamonds, which have a step-cut pattern for a more subtle shine, the radiant cut has 70 facets, giving it a fiery brilliance comparable to a round-cut diamond.

Key Features of a Radiant Diamond:

✔ Brilliant-Cut Facets – Offers unmatched sparkle, even more than an emerald-cut diamond.
✔ Elongated Shape – The radiant cut maximizes carat weight at the surface rather than the depth, resulting in a genuinely larger look compared to other shapes of the same weight.
✔ Versatile Design – Looks stunning in a variety of settings, from classic solitaires to three-stone designs.
✔ Durability – The beveled corners make it more resistant to chipping compared to princess-cut diamonds.

 

Why Are Radiant Diamonds So Popular?

Radiant-cut diamonds have become one of the top choices for engagement rings over the past 8–10 years. Their combination of modern elegance, shape, and intense sparkle makes them stand out among other fancy-shaped diamonds.

Reasons for Its Popularity:

  • Incredible Sparkle: With its brilliant-cut facets, a radiant diamond reflects light beautifully, creating a dazzling effect.

  • Larger Appearance: The elongated shape makes the diamond appear larger than a round diamond of the same carat weight.

  • Unique Yet Timeless: It offers a contemporary look while maintaining the classic elegance of a traditional engagement ring.

  • Celebrity Influence: Many high-profile engagements have featured radiant-cut diamonds, further fueling demand.

 

Celebrities with Radiant-Cut Engagement Rings

The radiant-cut diamond has become a favorite among celebrities, further increasing its popularity. Some of the most famous radiant-cut engagement rings include:

  • Drew Barrymore – Wore a 4-carat radiant-cut diamond in a classic setting.


Choosing the Best Radiant Diamond

To select the best radiant-cut diamond, you’ll need to consider cut, color, clarity, and carat weight while also keeping in mind unique factors like facet arrangement and length-to-width ratio.

1. Ideal Cut for Maximum Sparkle

Unlike round diamonds, radiant-cut diamonds do not have an official "ideal cut" standard. However, a well-cut radiant diamond should have:
✔ A length-to-width ratio of 1.25 to 1.50 for an elongated look (or 1.0 for a square shape).
✔ A well-balanced facet arrangement to avoid uneven light reflection.

2. Color Considerations

Radiant-cut diamonds tend to retain more color than round diamonds. If you want a bright white appearance, choose:

  • Lab-Grown Diamonds: D-F color for a colorless look.

  • Natural Diamonds: D-H color for near-colorless beauty.

3. Clarity Recommendations

Because radiant-cut diamonds have a brilliant facet pattern, they effectively hide imperfections. This means you can prioritize color over clarity and still get an eye-clean diamond.
✔ VS1-VS2 clarity is ideal for a balance of quality and value.
✔ SI1-SI2 clarity can still appear flawless when carefully selected (like in Benz & Co’s ready-to-ship collection).

4. Best Carat Size for a Radiant Diamond

Due to its elongated shape, a 1.50-carat radiant-cut diamond may appear as large as a 2-carat round diamond, making it an excellent choice for those looking to maximize size.

 

Best Settings for Radiant Engagement Rings

Radiant-cut diamonds look stunning in various ring settings, including:

✔ Solitaire – Highlights the diamond’s shape and brilliance.
✔ Hidden Halo – Adds extra sparkle while keeping a sleek look.
✔ Thin Band/Pavé – Complements the elongated shape with added elegance.
✔ Three-Stone – Pairs beautifully with side stones for a classic appeal.
✔ Bezel – A modern, protective setting that enhances the diamond’s durability.
