Diamond Cut Buying Guides
Radiant Diamond Buying Guide
Radiant cut diamonds elegantly combine the intense sparkle of round brilliant cuts with the sleek geometry of square or rectangular shapes, resulting in diamonds that showcase remarkable brilliance, durability, and visual impact. Created by Henry Grossbard in the late 1970s, the radiant cut incorporates 70 precisely arranged facets, enhancing both its brightness and fire. Its versatile shape makes it an ideal choice for various jewelry settings, from classic solitaires to intricate halo designs.
Radiant cut diamonds often appear larger than their actual carat weight due to their shape, offering excellent value compared to traditional round diamonds. When selecting a radiant cut diamond, consider an H colour grade or higher and a clarity grade of SI1 or SI2 for an optimal balance of quality and affordability.
It's essential to consider the "bowtie effect"—a potential dark area across the diamond's center—and select stones carefully to minimize its visibility. The bowtie is caused by light leakage, caused by misalignment of facets. Within this dark area, light is entering the diamond and exiting via the pavilion instead of reflecting back to the eye. Thus creating the dark area you see when you view the diamond.
The radiant cut is notable for its beveled corners, which not only provide a unique aesthetic appeal but also significantly improve the stone's durability, reducing the risk of chipping. This makes radiant cuts particularly suitable for everyday wear and active lifestyles.

When evaluating radiant cut diamonds, closely inspect the corners for evenness and symmetry to maintain aesthetic harmony and structural integrity. Ultimately, visual assessment is key, as personal preference greatly influences the ideal choice of diamond shape and proportions. Consider viewing diamonds in various lighting and settings to ensure you choose a radiant cut diamond that truly resonates with your style and preference.
