Summary
When it comes to choosing the perfect engagement ring, a radiant cut diamond comes as an unmatched brilliance for diamonds and contemporary style and design.
This radiant cut diamond engagement ring exudes a combination of a modern twist with timeless classic diamond, which makes it dazzling. In this guide by Loose Grown Diamond, you can get to know everything about radiant cut engagement rings.
What Is a Radiant Cut Diamond?

A radiant cut diamond is a combination of elegance and luxury, featuring the shape of an emerald cut with a rectangular or square shape and a round cut. The first radiant cut diamond was created by a master diamond cutter, Henry Grossbard, in 1977, mixing the features of two different shapes. The result was an elegant rectangular or square shape with 70 step-cut facets, enhancing the overall brilliance and maintaining a structured look.
A radiant cut diamond is different from other shapes like the Asscher cut as it maximizes more light due to step-cut facets, casting an exceptional shine and sparkle. The cut of the diamond also influences the overall color and clarity, giving it a flattering look.
Key Factors to Consider When Choosing a Radiant Cut Engagement Ring
Set a Budget
It is better to decide beforehand how much you plan to spend, considering your overall financial situation. While it’s common according to tradition to see the idea that an engagement ring should cost two or three months’ salary. But practically, it is important to consider your realistic budget, making your choices more precise.
Cut Quality
The cut quality of a radiant cut diamond influences the overall brilliance. While buying a radiant cut diamond engagement ring, you should look for the Length-to-width ratio. It represents the diamond’s proportion. A ratio of 1.00 to 1.05 gives a square shape, and 1.20-1.30 provides a more rectangular appearance.
The other is the bow-tie effect, which is a shadow effect that looks like a bow-tie and sometimes appears in elongated cuts. A radiant cut diamond with high quality reduces this shadow effect.
About the 4Cs
When buying a radiant diamond engagement ring on a budget, focus on the 4Cs—cut, color, clarity, and carat weight. The cut is the most important factor affecting how well the diamond reflects light and its overall sparkle. But GIA doesn’t grade radiant diamonds based on cut factor. For color, diamonds in the G to H range offer a colorless appearance but at a lower cost.
For clarity, radiant shapes have very few inclusions. So, you can go for slightly lower clarity without compromising the quality. This shape tends to look bigger than other cuts, which makes them higher carat weight.
Choose the Best Setting & Metal
The metal you choose for the engagement ring band can greatly affect the price.
White Gold: White gold looks similar to platinum but at a more budget-friendly cost.
Yellow Gold: Yellow gold is classic and timeless. It’s more affordable and doesn’t require as much maintenance compared to white gold.
Rose Gold: If you want something more unique, rose gold is a beautiful and affordable option. It’s gaining popularity for its warm and romantic hue.
For metal settings, you might prefer Halo, which amplifies the shape and sparkle with its mirror-effect. Solitaire setting highlights the big centre stone and its shape, while a three stone setting adds a vintage appeal.
Pros & Cons Of Radiant Cut Engagement Rings
Like any other diamond shape, radiant cuts also have their own unique pros and cons. Let’s check what the pros and cons are that one can look for while buying radiant-cut diamond engagement rings.
Pros
- More durable as compared to other shapes due to its curved corners.
- It has more brilliance and sparkle than the classic round-cut diamond.
- It is one of the most affordable shapes due to less demand, and the cut preserves rough diamonds, making less amount go to waste.
Cons
- The cut holds a depth to the diamond, which makes the base heavy. It can reduce the diamond’s brilliance.
- The cut of the diamond sometimes shows more color than the round cut.
- This shape is not graded for the cut for GIA, which makes the visual inspection essential while buying.
Do Radiant Cut Diamonds Look Bigger?

As discussed earlier, radiant cut diamonds tend to look bigger than other cuts with the same carat weight. This happens due to their large surface area and soft, cropped corners. This shape creates an illusion of a substantial stone.
The elongated rectangular or square shape adds length to the diamond that makes your finger appear longer, slimmer, and flattering.
How to Care for Your Radiant Cut Engagement Rings?
To clean your ring, use a soft brush to rub the stone after soaking it in mild, warm, soapy water. This will remove all the dust particles accumulated on the stone. Getting scheduled cleaning and inspection with professional geologists once or twice a year can help in identifying any loose prongs or stone settings and repairing them.
It is best to avoid wearing rings during any heavy-duty activities, such as swimming, to prevent exposure to harsh chemicals that can harm the diamond.
Conclusion
Radiant cut diamond engagement rings offer a perfect combination of brilliance, elegance, and luxury. While selecting a diamond for your loved one, it is important to consider some factors that can help in getting your desired piece. While looking for the ring, get your size identified with the ring size chart available on the Loose Grown Diamond website, which helps you get the perfect fit.
