The Radiant diamond cut is a square or rectangular mixed cut, combining the brilliance of the Round cut and the elegance of the Emerald cut. With a structure of 70 sharp facets and four beveled corners, the Radiant cut not only optimizes fire (sparkle) but also offers high durability, making the diamond appear significantly larger than its actual carat weight.
Let’s explore in detail the origin, technical characteristics, and standards for choosing the perfect Radiant cut right below.
What is the origin of the Radiant diamond cut?
In 1977, craftsman Henry Grossbard created a turning point for the jewelry industry when he introduced the Radiant cut. This was considered a revolution that changed the way people viewed square/rectangular stones, which had often been regarded as less brilliant than round diamonds.
- Name: "Radiant" means brilliant, reflecting Grossbard’s ultimate goal of creating a geometric cut that possessed "fire" comparable to round cuts (Round Brilliant).
- Meaning: This cut allows buyers to own a stone with a large surface area while still ensuring extremely high sparkle.

What outstanding features does the Radiant diamond cut have?
The Radiant cut possesses impressive technical specifications, making it a top choice for colored diamonds and large-sized jewelry.
- 70-facet structure: The large number of facets enhances light refraction, making the stone sparkle from every angle.
- Shape and durability: It has a shape similar to the Emerald cut, but the corners are carefully beveled, helping reduce the risk of chipping compared to the Princess cut (pointed corners).
- Ability to hide imperfections: Thanks to its complex interwoven facet structure, the Radiant cut hides inclusions and impurities extremely well.
- Color optimization: This is the most ideal cut for colored diamonds because the structure helps retain and reflect the stone’s natural color tone more vividly.

Standards for choosing a Radiant diamond according to the 4Cs
To optimize both budget and aesthetics, you need to pay attention to the technical specifications when evaluating a Radiant diamond:
Length/Width Ratio (L/W)
- Square shape: 1.00 – 1.05.
- Rectangular shape: 1.20 – 1.30.
Clarity: Because Radiant hides flaws very well, you only need to choose a VS1 or VS2 grade to achieve an "eye-clean" state, helping save costs.
Color: Radiant tends to retain color. If you prefer pure whiteness, choose color grade H or higher. If choosing colored diamonds (yellow, pink), Radiant is the number one choice.
Depth: It should be in the range of 61% – 69% to ensure light does not leak through the bottom.
