About Cushion Cut Lab Grown Diamonds
Cushion cut lab grown diamonds are one of the most beloved and enduring diamond shapes in the world — combining the soft, romantic appeal of rounded corners with a brilliant facet pattern that delivers extraordinary fire and sparkle. With a history spanning over two centuries, the cushion cut remains a timeless choice for those who appreciate classic elegance with a modern twist. At Variation, our certified collection brings you hundreds of ethically created cushion cut lab grown diamonds at prices that simply cannot be matched by mined stones.
What Is a Cushion Cut Diamond?
The cushion cut diamond — sometimes called the pillow cut — is a square or rectangular diamond with soft, rounded corners and a brilliant facet pattern typically featuring 58 to 64 facets. One of the oldest diamond cuts in existence, the cushion cut was the most popular diamond shape in the world for nearly two centuries before the round brilliant cut emerged in the early 20th century.
Its large, open facets and distinctive crushed ice or chunky facet patterns create a unique play of light — delivering a warmer, more romantic sparkle than the sharp precision of modern brilliant cuts. Today the cushion cut has experienced a remarkable resurgence in popularity, becoming one of the top choices for engagement rings worldwide.

How to Choose the Right Cushion Cut Lab Grown Diamond
1. Chunky vs Crushed Ice Facet Pattern
The most important choice unique to cushion cut diamonds is the facet pattern. A chunky cushion has larger, well-defined facets that produce bold flashes of light similar to a round brilliant. A crushed ice cushion has smaller, fragmented facets that produce a glittery, sparkling appearance similar to a radiant cut. Neither is superior — the choice is entirely personal preference.
2. Choose Square or Rectangular
A length-to-width ratio of 1.00–1.05 produces a classic square cushion. A ratio of 1.10–1.20 produces a more elongated rectangular cushion. Square cushions are the most traditional and popular choice while rectangular cushions offer a more distinctive, modern look.
3. Prioritize Cut Quality
Cushion cut 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 the best light performance and most pleasing appearance.
4. Color Recommendations
Cushion cuts retain color more than round diamonds due to their deeper pavilion and larger facets. 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.
5. Clarity Sweet Spot
VS1–VS2 clarity is the sweet spot for cushion cut diamonds. The chunky facet pattern can make inclusions slightly more visible than brilliant cuts, so VS2 eye-clean stones are an excellent choice. For crushed ice cushions, SI1 eye-clean stones can offer outstanding value.

Frequently Asked Questions
Are cushion 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.
What is the difference between a chunky and crushed ice cushion cut?
A chunky cushion cut has larger, well-defined facets that produce bold flashes of light. A crushed ice cushion has smaller, fragmented facets that create a glittery, sparkling appearance. Both are beautiful — the choice comes down to personal preference for sparkle style.
What is the difference between a cushion cut and a radiant cut?
Both are brilliant cut diamonds with similar facet patterns but they differ in shape and character. A cushion cut has soft, rounded corners and a romantic, vintage feel. A radiant cut has straight sides and trimmed corners giving it a more geometric, modern appearance.
What length-to-width ratio is best for a cushion cut diamond?
A ratio of 1.00–1.05 produces the most classic square cushion shape. A ratio of 1.10–1.20 produces a more elongated rectangular cushion. The best ratio depends entirely on personal preference and the setting style chosen.
