About Cushion Cut Lab Grown Diamond Rings
Variation's cushion cut lab grown diamond ring collection celebrates one of the most romantically beautiful and distinctive diamond shapes — the cushion cut's soft, rounded corners and distinctive brilliant facet pattern delivering a warm, luminous brilliance that is unlike any other diamond shape. Every ring in our collection features an IGI certified cushion cut lab grown diamond in D to F color and VVS1 to VS2 clarity — crafted in 18K yellow, white, or rose gold and priced up to 80% less than equivalent natural diamond rings. The cushion cut has been one of the most beloved diamond shapes for over two centuries — its timeless romantic character making it one of the most enduring and meaningful engagement ring diamond choices available.
Why Choose a Cushion Cut Lab Grown Diamond Ring?
The cushion cut combines a romantic square or rectangular shape with soft, rounded corners and a distinctive brilliant facet pattern that delivers a warm, luminous glow unlike the sharp, directional brilliance of a round or princess cut. In a ring setting, the cushion cut's distinctive light performance — with larger, broader flashes of brilliance rather than the sharp scintillation of a round brilliant — creates a deeply romantic and characterful diamond presence that is both timelessly elegant and distinctively individual.

What Makes Variation's Cushion Cut Diamond Rings Special?
At Variation, our cushion cut lab grown diamond ring collection reflects our commitment to showcasing the romantic warmth and distinctive brilliance of the cushion cut in the most beautiful and carefully curated ring settings. Our cushion cut diamonds are available in both chunky and crushed ice facet patterns — the chunky pattern delivering bold, dramatic flashes of brilliance while the crushed ice pattern creates an intensely sparkling, glittery appearance across the stone's face. For a cushion cut ring that is truly one of a kind, our custom design service allows you to create a completely bespoke piece around the diamond of your choice.
How to Choose the Best Cushion Cut Lab Grown Diamond Ring
Chunky vs Crushed Ice Cushion Cut
The most distinctive choice in a cushion cut ring is between the chunky and crushed ice facet patterns. A chunky cushion — with larger, more defined facets — produces bold, dramatic flashes of light that are visible from any distance and create a more classic and timeless cushion cut appearance. A crushed ice cushion — with smaller, more fragmented facets — produces an intensely glittery, sparkling appearance across the stone's full surface, creating a more contemporary and dazzling effect. Always view the stone face-up before purchasing to assess which pattern suits your aesthetic preference.
Choose the Right Cushion Cut Proportions
Cushion cuts are available in square and rectangular proportions — each creating a distinctively different visual impact in a ring setting. A square cushion — with a length-to-width ratio of 1.00 to 1.05 — creates a bold, symmetrical presence that is perfectly suited to classic solitaire and four-prong settings. A rectangular cushion — with a ratio of 1.10 to 1.20 — creates a slightly more elongated presence that faces up slightly larger and can create a more flattering effect on the finger. Consider the wearer's personal aesthetic and finger proportions when choosing between square and rectangular cushion cut proportions.
Choose the Right Setting Style
The cushion cut's soft rounded corners complement a range of setting styles particularly beautifully. A classic four-prong solitaire setting with one prong at each corner showcases the cushion cut's soft silhouette most purely. A halo setting surrounds the center cushion with a matching cushion-shaped crown of smaller accent diamonds — amplifying both the center stone's apparent size and the warm, romantic character of the cushion cut. All Variation cushion cut rings are crafted in 18K gold — yellow gold is a particularly beautiful choice for cushion cuts, complementing their warm, romantic brilliance.

Frequently Asked Questions
What makes the cushion cut unique compared to other diamond shapes?
The cushion cut is unique for its combination of a square or rectangular shape with soft, rounded corners and a distinctive brilliant facet pattern that delivers a warm, luminous glow unlike any other diamond shape. Rather than the sharp, directional brilliance of a round or princess cut, the cushion cut produces broader, warmer flashes of light that create a deeply romantic and characterful diamond presence. Its vintage-inspired character and distinctive light performance make it one of the most individually expressive diamond shapes available.
What is the difference between a chunky and crushed ice cushion cut?
A chunky cushion cut features larger, more defined facets that produce bold, dramatic flashes of brilliance — creating the most classic and recognisable cushion cut appearance. A crushed ice cushion cut features smaller, more fragmented facets that produce an intensely glittery, sparkling appearance across the full surface of the stone — a more contemporary and dazzling effect. Both are beautiful in ring settings — the choice is personal preference for light performance and aesthetic character.
Is the cushion cut a good choice for an engagement ring?
Yes — the cushion cut is one of the most romantic and beloved engagement ring diamond shapes in the world. Its soft rounded corners, warm luminous brilliance, and vintage-inspired character make it deeply personal and timelessly beautiful. Its two centuries of enduring popularity are a testament to its timeless romantic character. At up to 80% less than equivalent natural diamond cushion cut rings, a Variation lab grown diamond cushion cut engagement ring is an outstanding choice.
What ring settings work best with a cushion cut diamond?
Cushion cut diamonds are particularly beautiful in classic four-prong solitaire settings that showcase the stone's soft silhouette, halo settings that surround the center stone with a cushion-shaped crown of accent diamonds, and pavé band settings that add continuous sparkle along the band. Yellow gold settings are a particularly romantic and complementary choice for cushion cut diamonds, warming the stone's already warm and luminous brilliance.
What is the ideal length-to-width ratio for a cushion cut engagement ring?
A length-to-width ratio of 1.00 to 1.05 produces the most classic square cushion cut — perfectly symmetrical and suited to classic prong and halo settings. A ratio of 1.10 to 1.20 produces a slightly rectangular cushion that faces up slightly larger. The ideal ratio depends on the wearer's personal aesthetic preference and finger proportions. Our team can advise on the best cushion cut proportions for any specific vision.
