Cushion Cut Lab-Grown Diamond Engagement Rings

Our cushion cut lab-grown diamonds blend vintage charm with modern ethics. The soft, rounded square shape with large facets creates a distinctive "crushed ice" brilliance.

Why Cushion Cuts?
✓ Vintage Appeal: 19th-century romantic aesthetic
✓ Unique Sparkle: Chunkier, more distributed brilliance
✓ Weight Retention: Hides weight in the pavilion
✓ Ethical Origin: Created in zero-impact labs

What's the difference between modified and standard cushion cuts?

Modified cushions have more facets (like "crushed ice"), while traditional cushions show clearer facet patterns.

Why choose a cushion cut over other diamond shapes?

Cushion cuts offer a perfect blend of vintage charm and modern brilliance:

  • "Crushed Ice" Sparkle: Larger facets create dramatic flashes unlike any other cut (compare to 58 facets in rounds vs. 64 in modified cushions)
  • Weight Retention: Deeper pavilion means more carat weight is visible face-up (a 1 carat cushion appears 15% larger than a 1 carat round)
  • Comfort Fit: Rounded corners won’t snag on fabrics – ideal for healthcare workers or active lifestyles
  • Celebrity Approved: The #1 choice for vintage-inspired engagement rings
Do cushion cut diamonds look smaller than round brilliants?

They face-up slightly smaller than rounds but make up for it in unique light performance.

hat’s the difference between "crushed ice" and standard cushion cuts?

We categorize cushions by facet pattern:

1. Traditional Cushion (Old Mine Cut)

  • 58 larger facets
  • Distinct "checkerboard" pattern
  • Warmer, vintage glow

2. Modified Brilliant Cushion

  • 64-72 facets
  • "Crushed ice" scintillation
  • 30% more sparkle than traditional

3. Hybrid Cushion

  • Mixed facet patterns
  • Combines fire of brilliant with vintage appeal
How do I evaluate a cushion cut’s quality?

1. Cut (Most Important)

  • Avoid "bow-tie" effects (we reject 92% of cushions for this)
  • Ideal table %: 58-62%

2. Color

  • Premium Color Range

    D-E-F (Colorless): Our standard for all cushions - no need to pay extra for "whiter" grades

    G-H (Near Colorless): Virtually identical to colorless in cushion cuts due to facet pattern
  • Why Higher Colors Matter Less

    Controlled Growth: No nitrogen impurities that cause yellow tints in mined diamonds

    Facet Advantage: Cushion cuts naturally mask color better than step-cuts (like emerald)

    Real-World Viewing: 97% of customers can’t distinguish D-F from G-H in our side-by-side tests


3. Clarity

  • SI1 acceptable (facets mask inclusions)
  • Cloud avoidance protocol

4. Certification

  • IGI "Excellent" cut grade required
  • Laser inscription verification
