What Is A Radiant Cut Diamond?

Diamonds have always been a popular choice for jewelry, and one of the most stunning cuts available is the radiant cut. In this blog, we'll explore what a radiant cut diamond is, its history, characteristics, and how to care for it.


Diamonds are a girl's best friend, but what exactly is a radiant cut diamond? A radiant cut diamond is a unique and beautiful diamond that is cut with a combination of the facets of a round brilliant cut and the emerald cut, resulting in a rectangular or square shape with beveled corners. It is a versatile cut that can look stunning in various jewelry designs.

History of Radiant Cut Diamonds

Radiant cut diamonds originated in the 1970s, invented by Henry Grossbard, who wanted to combine the brilliance of round diamonds with the elegant lines of emerald-cut diamonds. Radiant cut diamonds quickly gained popularity and became one of the most sought-after diamond cuts in modern times.

Characteristics of Radiant Cut Diamonds

Radiant cut diamonds have unique features that distinguish them from other diamond cuts. They have a rectangular or square shape, with cut corners that enhance the diamond's brilliance. The cut can range from rectangular to square, with a length to width ratio of anywhere between 1.00 and 1.50. Compared to other diamond cuts, radiant cut diamonds have more facets, making them more sparkly and brilliant. They also have a larger face-up size, making them appear larger than other diamond cuts of the same carat weight.

How to Buy a Radiant Cut Diamond

When purchasing a radiant cut diamond, there are several factors to consider, such as cut, color, clarity, and carat weight. Cut is the most critical factor as it affects the diamond's sparkle and brilliance. The color of the diamond is also important, with a preference for colorless or near-colorless diamonds. Clarity refers to the presence of flaws or inclusions in the diamond, with a preference for diamonds with fewer inclusions. Carat weight refers to the size of the diamond, with larger diamonds being more expensive.

Radiant Cut Diamond Settings

Radiant cut diamonds can be set in various types of settings, including solitaire, halo, and three-stone settings. Solitaire settings highlight the diamond's beauty, while halo settings add extra sparkle and make the diamond appear larger. Three-stone settings feature a radiant cut diamond flanked by two smaller diamonds, creating a stunning and elegant look. Radiant cut diamonds can also be paired with other gemstones, such as sapphires, for a colorful and unique look.

Caring for Your Radiant Cut Diamond

To keep your radiant cut diamond looking its best, it is essential to care for it properly. Avoid wearing your diamond while doing strenuous activities and remove it before using chemicals or cleaning products. To clean your diamond, use a soft-bristled brush and a gentle cleaning solution, such as soap and water. You can also take your diamond to a professional jeweler for cleaning and maintenance.


In conclusion, radiant cut diamonds are a beautiful and unique choice for jewelry. With their exceptional brilliance and versatility, they are a popular choice for engagement rings, earrings, and necklaces. When purchasing a radiant cut diamond, consider the cut, color, clarity, and carat weight, and choose a setting that highlights its beauty. With proper care and maintenance, your radiant cut diamond will continue to sparkle for years to come.
