The Radiant diamond cut is a mixed square or rectangular cut, combining the brilliance of the Round cut and the elegance of the Emerald cut. With a sharp 70-facet structure and four beveled corners, the Radiant cut not only optimizes fire (sparkle) but also has high durability, making the diamond look significantly larger than its actual weight.
Let's delve into the details of the origin, technical specifications, and selection criteria for a perfect Radiant cut diamond below.
What is the origin of the Radiant diamond cut?
In 1977, artisan Henry Grossbard revolutionized the jewelry industry by introducing the Radiant cut. This was considered a revolution that changed the perception of square/rectangular stones, which were often deemed less brilliant than round diamonds.
- Name: "Radiant" means brilliant, reflecting Grossbard's ultimate goal of creating a shaped cut that possessed the same "fire" as a Round Brilliant cut.
- Meaning: This cut allows consumers to own a stone with a large surface area while ensuring extreme sparkle.

What are the outstanding features of the Radiant diamond cut?
The Radiant cut boasts impressive technical specifications, making it a top choice for colored diamonds and large jewelry pieces.
- 70-facet structure: The large number of facets enhances light refraction, making the stone sparkle from every angle.
- Shape and durability: It resembles the Emerald cut but with meticulously beveled corners, minimizing the risk of chipping compared to the Princess cut (sharp corners).
- Ability to hide inclusions: Due to its complex, interlocking facet structure, the Radiant cut is excellent at concealing inclusions and blemishes.
- Optimizes color: This is the ideal cut for colored diamonds because this structure helps to hold and reflect the stone's natural hue more intensely.

Criteria for choosing a Radiant diamond based on the 4Cs
To optimize your budget and aesthetics, you should pay attention to the technical specifications when evaluating a Radiant diamond:
Length-to-Width Ratio (L/W)
- Square shape: 1.00 – 1.05.
- Rectangular shape: 1.20 – 1.30.
Clarity: Since the Radiant cut is very good at hiding imperfections, choosing VS1 or VS2 clarity is sufficient for an "eye-clean" appearance, helping to save costs.
Color: Radiant diamonds tend to retain color. If you prefer pure whiteness, choose a color grade of H or higher. If you opt for colored diamonds (yellow, pink), Radiant is the number one choice.
Depth: Should be between 61% and 69% to ensure light is not lost through the pavilion.
