If you’re in the market for a standout gem, you’re in the right place. This guide dives deep into everything you need to know about radiant cut diamonds. By the end, you’ll be equipped to make an informed choice that sets your diamond apart from traditional shapes.

What is a Radiant Cut Diamond

Radiant cut diamonds, also known as radiant diamonds, captivate with their brilliant fusion of brilliance, fire, and shape. Their hybrid nature and captivating beauty come from combining the best aspects of round brilliant cut diamond and emerald cut diamonds.

This exceptional diamond cut makes up only about 2% of diamonds sold worldwide, making them a unique find in the casual fashion world.

Boasting a stunning, vibrant appearance, a radiant cut diamond represents a hybrid cut with the following features:

  • 70 facets

  • Beveled corners for added durability

  • Octagonal shape

  • Unique facet structure

These characteristics set radiant cut diamonds apart from other diamond shapes, offering an eye-catching and dazzling appearance.

The History of Radiant Cut Diamonds

Henry Grossbard envisioned and designed the radiant cut in 1977 to combine the best features of existing cuts, creating a remarkable diamond cut. His innovative design paved the way for a new generation of diamond cuts, offering a unique alternative to traditional round brilliant and emerald cut diamonds.

Pros and Cons

Numerous advantages come with radiant cut diamonds, including extraordinary brilliance, fire, and sparkle, a larger perceived size, better durability, and excellent value for money. It’s the perfect shape for those who want to enjoy the elongated appearance while getting more brilliance and sparkles.

However, there are no GIA cut quality grades for radiant cut diamonds, which means personal evaluation and appreciation of the diamond’s unique features are crucial. Picking “excellent” polish and symmetry graded diamonds is not enough, you need to look for specific measurements to make sure you are maximizing the light performance of the radiant cut.

Radiant Cut Diamond Anatomy

A radiant cut diamond’s anatomy comprises its facet structure, beveled corners for durability, and various length-to-width ratios, bowtie effects, depth, and table measurements.

Understanding these aspects of a radiant cut diamond will help you appreciate its unique beauty and make an informed decision when choosing the perfect stone.

Facet Structure

When it comes to radiant cut diamonds, the facet structure is the unsung hero that amps up the brilliance and fire. So, what’s the big deal about having 70 facets? Well, each facet acts like a tiny mirror, reflecting light in multiple directions. The more facets, the more opportunities for light to bounce around, creating that mesmerizing sparkle we all love.

In a radiant cut diamond, the facets are arranged in a unique pattern that maximizes light reflection. This not only gives the diamond its vibrant, lively appearance but also enhances its overall brilliance. So, if you’re all about that sparkle, the radiant cut’s 70 facets make it a top contender for capturing and reflecting light like no other.

Beveled Corners

Robust protection is provided by beveled corners in a radiant cut diamond and enhance the diamond’s appearance. These expertly cut angles not only give the radiant cut diamond a distinctive look but also increase its durability, making it less prone to chipping or breakage.

The beveled corners of a radiant cut diamond are cut at precise angles to ensure maximum

Length-to-Width Ratio, Bowtie Effect, Depth and Table

When choosing a radiant cut diamond, it’s crucial to consider factors like the length-to-width ratio, as it significantly impacts the diamond’s visual appeal and light performance. An optimal ratio ranges from 1.11 to 1.5:1, enhancing its brilliance.

Be cautious of a dark band across the center, resembling a black bowtie, as it hinders light reflection and diminishes the diamond’s sparkle.

Comparing Radiant Cut Diamonds with Other Diamond Shapes

When you contrast radiant cut diamonds with other diamond shapes, such as princess, cushion, and emerald cuts, it’s essential to consider the differences in shape, brilliance, fire, and clarity.

Each diamond shape has its unique characteristics, allowing you to choose the one that resonates most with your personal style and taste.

Radiant vs Princess Cut

Radiant cut diamonds and princess cut diamonds may seem similar, but they have key differences that set them apart. Radiant cuts come with beveled corners, giving them an elongated look. This feature not only adds durability but also enhances the diamond’s brilliance. On the other hand, princess cut diamonds have sharp corners and a more square shape, which makes them stand out for their generaly higher light performance.

Radiant vs Cushion Cut

Radiant cut diamonds and cushion cut diamonds each have their own unique appeal, largely influenced by their edges and corners. Radiant cuts feature sharper edges, focusing on maximizing the stone’s light performance. Cushion cuts, on the other hand, have softer, rounded corners that resemble a cushion, hence the name.

Cushion cuts come in various styles like crushed ice, chunky, modified, and hearts and arrows, each offering different length-to-width ratios and light performance. Ultimately, the choice between radiant and cushion cuts boils down to personal preference and what you value most in a diamond’s appearance.

Radiant vs Emerald Cut

The cutting method predominantly differentiates radiant and emerald cut diamonds. Emerald cut diamonds belong to the step cut group and have long rectangular facets, giving them a sophisticated and elegant look. The magic of the emerald shape comes from its mirror effect, and less for it’s sparkles.

Radiant cut diamonds are in the brilliant cut group and have more facets, resulting in a dazzling and vibrant appearance. Both diamond cuts offer a unique aesthetic, but the choice between them depends on individual style and taste.

Choosing the Perfect Radiant Cut Diamond

Choosing the perfect radiant cut diamond involves assessing the following factors:

  • Cut quality

  • Color

  • Clarity

  • Carat weight

  • Length-to-width ratio

By considering these factors, you can ensure that you are selecting a radiant cut diamond that not only looks stunning but also offers excellent value for money.

Cut Quality

Choosing the Perfect Radiant Diamond: The Importance of Cut

When it comes to radiant cut diamonds, the cut quality is a game-changer. A well-cut radiant diamond will not only maximize brilliance but also cleverly mask any inclusions due to its extra facets. On the flip side, a poorly cut radiant diamond can look dull and lack that sought-after sparkle.

Radiant diamond cut recommendations:

  • Length-to-Width Ratio: Aim for a ratio between 1.11 and 1.5:1 to enhance the diamond’s brilliance and visual appeal.
  • Bowtie Effect: Watch out for a dark band resembling a black bowtie across the center, as it can hinder light reflection and reduce sparkle.
  • Table: 61-67.5
  • Depth: 65.3-70.5
  • Crown Angle: 9.5-15
  • Pavilion Angle: 49.5-56


By paying attention to these factors and recommendations, you’ll be well on your way to choosing a radiant diamond that truly shines.

Color and Clarity

Choosing the Right Color and Clarity for Radiant Cut Diamonds

Radiant cut diamonds are known for their brilliance, which can be a real advantage when it comes to color and clarity. The cut’s sparkle can effectively mask minor flaws, making it easier to find diamonds that appear eye-clean. Similarly, the brilliance can blend lower color grades, making any yellowish tint almost invisible.

Recommended Grades:

  • Clarity: The lowest clarity grade to consider is SI1, provided the inclusions aren’t visible to the naked eye.

  • Color: While a well-chosen J-I grade can work, opting for an H color will offer greater peace of mind and a more colorless appearance.

Radiant cut pricing

Factors such as carat weight, color, clarity, and cut quality influence radiant cut diamond pricing.

Conclusion - My Personal experience

This diamond shape is also cost-effective, thanks to lower demand and less carat waste during cutting. This allows you to either save some cash or invest in a larger, more stunning gem. Just make sure your radiant diamond is eye-clean and has the right measurements, and you’ll have a stone that truly shines.
