Radiant-Cut Diamonds

The radiant-cut diamond is considered to be the perfect balance between beauty and strength. Its unique cut design creates proportions that give this diamond a brilliant sparkle and a very durable structure unmatched by other sophisticated diamond shapes. Relatively new to the industry, every radiant-cut diamond offers the ideal brilliance for a high-end designer look without compromise. They are an excellent choice for a centre stone in jewellery or that all-important engagement ring.

What is a Radiant-Cut Diamond

The radiant-cut diamond is similar to the princess-cut diamond but with more brilliant facets. The radiant-cut diamond is a hybrid cut with 70 facets and unique cropped corners. The extra facets disperse light through the diamond, making it become one of the more brilliant square or rectangular shaped diamond cuts.


History of the Radiant-Cut Diamond

In 1977, master diamond cutter Henry Grossbard created the radiant cut with the goal of inspiring more interest in square and rectangular diamond shapes. To attain this, Grossbard married the techniques and structures behind the already-popular emerald and brilliant round shapes to create the vivacious sparkle and famous durability now synonymous with the radiant-cut.

As a result, the radiant cut first gained popularity in the 1980s, and is currently on top engagement ring wish lists today.

The radiant-cut diamond was the first diamond cut to feature a brilliant facet pattern on both the crown and pavilion. This shape owes its incredible sparkle to its 70 facets. As a point of reference, the only diamond cut that surpasses the radiant cut in brilliance is the round brilliant shape.


Differences Between a Radiant-Cut and Princess-Cut Diamond

While princess and radiant-cut diamonds share many features, and both cute are highly fashionable for engagement ring settings, when comparing the shapes there are several noticeable differences.

Princess vs. Radiant-Cut Diamonds – Shape
While the shapes of these two cuts are very similar, princess-cuts are mostly square with sharp edges. On the other hand, radiant-cut diamonds are either square or rectangular with cut corners. Because of its cut corners, the radiant diamond is well-suited to those with more active lifestyles as it does not have sharp corners that may get caught or chipped with a minor bump or impact.

Princess vs. Radiant-Cut Diamonds – Cut
Modern princess-cut diamonds have 76 chevron-shaped facets, a vertically cut pavilion, and feature a distinct “X” shape at the centre. The radiant-cut features a higher crown and smaller table. Thanks to its highly unique facet patterns, this cut also features a distinct circular pattern when viewed from the top.

Princess vs. Radiant-Cut Diamonds – Sparkle
Princess-cut diamonds feature reflections that consist of fewer colours due to their contrasting facets. The radiant-cut diamond's brilliant sparkle makes it a top choice for engagement rings and other romantic jewellery pieces. This results in a near-colourless diamond, which experts consider ideal.

Princess vs. Radiant-Cut Diamonds – Cost
Compared to radiant-cut diamonds, princess-cuts tend to cost less because they are typically cut from a rougher diamond.

When considering the differences between a radiant-cut and a princess-cut diamond for purchase, it is worthwhile to make a mental note of the above differences. However, the biggest deciding factor should always be your personal preference. If you are looking for a modern, elegant diamond shape that suits active lifestyles, the radiant-cut diamond may be your ideal diamond shape.


Grading System of Peoples Radiant-Cut Diamonds

At Peoples, we rely on trusted experts from different gemological laboratories to grade our precious stones.

To determine a diamond’s grade, these labs inspect each diamond under closely controlled lighting and viewing conditions. Trained grading professionals use highly calibrated measurement devices to capture important data for use in determining the radiant-cut diamond’s quality. These experts will then grade our radiant-cut diamonds on the following determinations:

Radiant-Cut Carat
Each diamond is measured using the carat weight system. Diamond experts use specially calibrated scales to ensure accurate measurements with weights measured to the hundred-thousandths of a carat. One metric carat equals 0.2 grams.

Radiant-Cut Clarity
Radiant-cut diamond clarity references the appearance of the stone, and it notes any blemishes or inclusions. Our experts grade diamond clarity as one of six grades – Flawless, Internally Flawless, Very Very Small Inclusions, Very Small Inclusions, Small Inclusions, or Imperfect.

Of course, much of diamond selection comes down to personal taste. Some blemishes may only be visible to a professional using specific equipment. Evaluating the clarity of a diamond can be as simple as noting whether it appears clear to the naked eye. You may prefer to know that your radiant-cut diamond is certified as Flawless while others may not mind minor blemishes that aren’t visible unless inspecting them with special equipment.

If your partner prefers a more ideal appearance, opt for a Flawless or Internally Flawless diamond. If small imperfections do not stand out to your partner, then you may prefer a Very Small Inclusions or Small Inclusions grade radiant-cut stone.

Radiant-Cut Colour
The industry standard system for grading radiant-cut diamond colour begins with a D grade (colourless) and continues with increasing levels of colour to a Z grade.

Diamonds are compared to master stones with known colour grades. Diamond experts utilize master stone sets that are chosen based on rigorous standards then tested prior to use. Master stones help experts determine diamond colour grades. Each master stone set must surpass rigorous standards before use in determining colour grades.

The human eye associates diamond colour with overall diamond size and its settings. The human eye may not detect small differences in diamond colour which account for significant differences in diamond price. Additionally, the setting colour and material chosen for the radiant-cut diamond can make a considerable difference in the colour of the diamond. For instance, of your diamond has a hint of yellow colour to it, it will appear brighter and lighter in a warm yellow gold setting.
