About Radiant Cut Lab Grown Diamonds
Radiant cut lab grown diamonds offer a rare and striking combination — the extraordinary brilliance of a round brilliant cut in a sleek rectangular or square shape. Bold, versatile, and exceptionally brilliant, the radiant cut is the perfect choice for buyers who want the best of both worlds. At Variation, our certified collection brings you hundreds of ethically created radiant lab grown diamonds at prices that simply cannot be matched by mined stones.
What Is a Radiant Cut Diamond?
The radiant cut diamond was created in 1977 by master diamond cutter Henry Grossbard, making it one of the first rectangular diamonds to feature a complete brilliant cut facet pattern on both the crown and pavilion. With 70 facets precisely arranged to maximize light return, the radiant cut delivers a level of fire and brilliance previously only achievable in round diamonds.
Available in both rectangular and square proportions, the radiant cut is distinguished by its trimmed corners — a practical design feature that reduces the risk of chipping while adding to its bold, geometric appeal.
Why Choose Lab Grown Over Mined Radiant Cut Diamonds?
Lab grown diamonds are physically, chemically, and optically identical to mined diamonds. The only difference is their origin — and that difference works entirely in your favor.
- Up to 80% more affordable than equivalent mined diamonds
- Conflict-free and ethically created with zero mining impact
- Eco-friendly — significantly lower carbon footprint than earth-mined stones
- IGI/GIA certified — graded to the same strict standards as natural diamonds
- Same hardness, same brilliance, same forever — a lab grown diamond is a real diamond
Choosing a radiant cut lab grown diamond means you get a larger, more brilliant stone for the same budget — without compromise.

How to Choose the Right Radiant Cut Lab Grown Diamond
1. Choose Rectangular or Square
Radiant cuts come in both rectangular and square proportions. A length-to-width ratio of 1.20–1.50 produces a classic rectangular shape, while a ratio of 1.00–1.05 produces a square radiant. Both are equally brilliant — the choice is purely personal preference.
2. Prioritize Cut Quality
Like oval cuts, radiant diamonds do not receive an official cut grade on their certificate. Assess cut quality through symmetry and polish grades — always choose Excellent symmetry and Excellent or Very Good polish for maximum light performance.
3. Color Recommendations
Radiant cuts retain color more than round diamonds due to their deep pavilion. For white gold or platinum settings, choose D–F color grades. For yellow or rose gold settings, G–H color grades pair beautifully and offer excellent value.
4. Clarity Sweet Spot
VS1–VS2 clarity is the sweet spot for radiant cut diamonds. The radiant cut's brilliant facet pattern does an excellent job of concealing inclusions, making VS2 an exceptional value choice for buyers seeking an eye-clean stone.
5. Check Symmetry Carefully
Symmetry is especially important in radiant cut diamonds. Uneven sides or misaligned facets are immediately visible in this geometric shape. Always choose Excellent or Very Good symmetry grades and view the stone face-up before purchasing.

Frequently Asked Questions
Are radiant cut lab grown diamonds real diamonds?
Yes. Lab grown diamonds are 100% real diamonds. They share the same physical, chemical, and optical properties as mined diamonds and are certified by the same internationally recognized grading laboratories.
How many facets does a radiant cut diamond have?
A radiant cut diamond features 70 facets — more than a standard round brilliant cut — delivering exceptional fire, brilliance, and scintillation from every angle.
What is the difference between a radiant cut and a cushion cut?
Both are brilliant cut diamonds with similar facet patterns, but they differ in shape. A radiant cut has straight sides and trimmed corners giving it a more geometric, modern appearance. A cushion cut has rounded corners and softer edges, giving it a more romantic, vintage feel.
What is the difference between a radiant cut and an emerald cut?
Both share a rectangular shape but are very different in character. A radiant cut is a brilliant cut with 70 facets that maximize sparkle and fire. An emerald cut is a step cut with large open facets that emphasize clarity and elegance over brilliance.
Are lab grown radiant cut diamonds cheaper than mined ones?
Yes — priced up to 80% less than an equivalent mined diamond, with no difference in beauty, durability, or certification.
