Radiant Cut Diamonds

Radiant cut diamond ring

History & Overview

The radiant cut diamond was first introduced in the 1970s. Henry Grossbard, from the Radiant Cut Diamond Company, was the person responsible for its development. It was one of the first cuts to have a complete brilliant-cut facet pattern applied to both the crown and pavilion, which gives it a more dazzling effect compared to other rectangular or square cuts .

Appearance

 Shape: The radiant cut is typically a rectangular or square shape diamond with cut corners. This gives it a silhouette somewhere between a princess cut diamond and an emerald cut diamond. Radiant cut diamonds can be either square or rectangular, but what sets them apart are the uniquely trimmed corners, which can help to prevent chipping. The radiant cut diamond features approximately 70 facets, maximizing light reflection. This intricate facet pattern produces a fiery intense brilliance, as the name suggests.

Certification & Grading

It is imperative that your diamond is accompanied by a certification from a reputable lab such as the GIA or known as the Gemological Institute of America. This certification verifies all the essential attributes of the diamond, from carat weight and clarity to symmetry and color.

Choosing a Radiant Cut Diamond: Variability in Length to Width Ratios: Radiant cut diamonds can vary quite a bit in terms of their proportions. Some are more square, with a length-to-width ratio close to 1.0, while others are more rectangular. The optimal ratio depends on personal preference, but those looking for a square shape should aim for a ratio between 1.00 and 1.05, while those looking for a more rectangular shape might prefer a ratio of 1.20 or more. 


Color: Due to its brilliance, the radiant cut diamonds can hide some color, so it's often recommended to consider diamonds in the G-H color range or better for a good balance between cost and appearance.

GIA Color Scale

    Clarity: Given the number of brilliant facets and a radiant cut diamond's reflective nature, minor inclusions or imperfections can be less visible in a radiant cut diamond than in some other cuts. Nevertheless, aiming for SI1 diamond clarity grade or better is often recommended to ensure the diamond appears clean to the naked eye. Avoid radiant cut diamonds with dark inclusions, as often dark inclusions may affect the light performance of the diamond.

GIA Clarity Scale

    Bow tie Effect: As with many elongated diamond shapes, some radiant cut diamonds might display a "bowtie" effect. This is a darker area in the shape of a bowtie that can appear across the width of the diamond. The visibility and prominence of the bowtie effect depend on the quality of the diamond's cut. 


Carat Weight and size perception: carat weight normally reflects a diamonds size, but you can a have a diamond of the same face up measurements with one weighing much more. This can be due to having a higher depth or larger table. 


Setting Styles for Radiant cut Diamond Engagement rings : When choosing a setting for a radiant cut diamond engagement ring, the primary consideration should be to protect and highlight the unique features of the diamond while aligning with the wearer's style and preference. Here are some popular setting styles for radiant cut diamond engagement rings: 


Solitaire Setting: This is the most classic and timeless choice for engagement rings. In this setting, a single radiant cut diamond takes center stage, usually held in place by prongs. The simplicity of a solitaire setting allows the diamond's brilliance and shape to shine without distraction.

Halo Setting: This involves surrounding the radiant cut diamond with a circle (or double circle) of smaller diamonds. This not only makes the center diamond appear larger but also adds extra sparkle and luxury to the overall look of the engagement ring.

Three-Stone Setting: Here, the radiant cut diamond is flanked by two smaller stones on either side. These side stones can be radiant cut as well, or they could be different diamond shapes like a trillion, baguette, or pear, depending on the desired look of the engagement ring.

Pavé Setting: This setting features small diamonds set closely together, paving the band. When combined with a radiant cut diamond center stone, it offers a continuous sparkle, making the engagement ring appear more dazzling.

Channel Setting: In this style, smaller diamonds are set between two strips of metal, forming a channel. This offers a sleek look and can be combined with a radiant cut center stone for a modern appearance.

Side Stone Setting: In addition to a three-stone setting, radiant diamonds can be complemented by various side stones set along the band, either intermittently or in a continuous line.

East-West Setting: While most radiant cut diamonds are set vertically (with the longer side aligned with the length of the finger), they can also be set horizontally in an East-West orientation. This offers a unique and modern twist on traditional engagement ring settings.

When choosing a setting for a radiant cut diamond, it's essential to consider the diamond's size, the ring's intended use (daily wear vs. occasional), the wearer's lifestyle (active vs. sedentary), and personal style preferences. Consulting with a professional jeweler can also provide valuable insights into finding the perfect setting for a radiant cut diamond.

    Comparison to other diamond shapes: Radiant cut diamonds vs. Princess cut diamonds: While both can be square or rectangular in shape, the radiant cut diamond has trimmed beveled corners and more facets, resulting in more brilliance. The princess-cut diamond has sharp pointed corners.

    Radiant cut diamond vs. Cushion cut diamond: Cushion cuts have a softer, pillow-like shape, rounded corners, and may appear more vintage, while radiant cut diamonds often look more contemporary due to their cut pattern & beveled corners.

    Popularity: Radiant cut diamonds have garnered significant popularity for a variety of reasons: 


    Brilliance and Fire: The primary attraction of the radiant cut diamonds is its remarkable brilliance and fire. Its faceting pattern is designed to maximize the reflection and refraction of light, leading to a vibrant display of colors and brightness. 


    Unique Design: The radiant cut diamond offers a blend of the best features of both round and emerald cut diamonds. It combines the brilliance of round cuts with the more geometric lines and cut corners of the emerald cut, producing a distinctive and appealing look. 


    Durability: The cut corners of radiant cut diamonds not only add to its design but also enhance its durability. Pointed corners, like those of a princess cut, can be more prone to chipping. The softened corners of a radiant cut make it less susceptible to damage, especially when set in a ring. 


    Versatility: Radiant cut diamonds are incredibly versatile. Whether set as a solitaire, accompanied by side stones, or even used in fancy colored diamond settings, this cut looks beautiful. Its design complements both modern and traditional jewelry styles. 


    Flattering Shape: Its shape, either square or rectangular, can appear flattering on the finger, especially the elongated rectangular versions which can visually lengthen and slim the appearance of one's fingers. Often radiant cut diamonds with longer ratios can visually appear longer because of the eye being drawn to the length of the diamond. 


    Flexibility in Color and Clarity Choices: Radiant cuts, due to their faceting structure, can often hide inclusions better than some other cuts. This means buyers might opt for slightly lower clarity grade without compromising the diamond's visual appeal. Similarly, while color is more noticeable than in round brilliants, a well-cut radiant can still look beautiful with a hint of color. 


    Cost-Effective: Compared to round brilliant cut diamond, which is the most popular diamond shape, radiant cut diamonds often come at a more attractive price point. 


    Distinctiveness: For those who want something different from the ubiquitous round brilliant cut diamond, but still desire brilliance and fire, the radiant cut is a perfect choice. While not as popular as round brilliant cut diamonds, radiant cut diamonds have garnered a loyal following due to their unique combination of shape and brilliance. They're often chosen by those who want something a bit different but still dazzling
