✦ Modern Faceting Engineering ✦

The Magic of 70 Brilliant Facets

Invented in 1977 by master diamond cutter Henry Grossbard, the radiant cut was born from a desire to unite the elegant emerald cut silhouette with the scintillating fire of a round brilliant.

Grossbard designed a complex 70-facet cutting arrangement featuring 25 crown facets, 8 girdle facets, and 37 pavilion facets. This dense network of intersecting planes creates a mesmerizing "crushed-ice" brilliance. Light enters and bounces in dozens of micro-reflections, effectively concealing microscopic internal crystal inclusions and maximizing optical fire.

Chipped Corner Protection

Beveled corners prevent snagging and chipping common in sharp princess cuts.

Inclusion Masking

Extreme scintillation masks SI1 and VS2 inclusions for superior value.

Frequently Asked Questions

Key facts and guidance about certified radiant cut lab created diamonds.

Yes, significantly. While an emerald cut uses step facets that create broad, calm "hall-of-mirrors" reflections, a radiant cut features 70 triangular and diamond-shaped facets that break light into hundreds of sparkling flashes (known as crushed-ice scintillation), delivering substantially more fiery sparkle.

The main difference lies in the corners and edges. A **radiant cut has straight sides with straight, cropped 45-degree corners**, giving it a crisp, geometric, modern aesthetic. A **cushion cut has rounded sides and soft pillow corners**, giving it a softer, romantic, vintage appearance.

The most popular bridal ratio is **1.35 to 1.45**. This ratio provides the ideal elongated rectangular proportions that visually lengthen the finger without making the stone appear overly narrow or shallow.

No. In fact, radiant cuts are one of the best shapes for masking inclusions! The dense 70-facet arrangement creates intense scintillation that scatters light across the table, making small inclusions virtually invisible to the naked eye. This allows buyers to comfortably choose VS2 or even eye-clean SI1 stones to maximize carat weight.

Direct from our Surat diamond factory, a certified 2 carat radiant cut lab grown diamond (D-F Color, VVS/VS Clarity) costs between $720 and $1,050 USD. In US retail stores, the same diamond costs $3,000 to $4,200 USD, and a mined counterpart costs $18,000+.
