Cushion Cut Lab Grown Diamond
Engagement Rings


The cushion cut diamond is the most romantic shape in fine jewelry, softly rounded corners, a pillow-like silhouette, and large facets that produce exceptional fire and the distinctive crushed ice sparkle no other shape replicates.

At Trusamra, every cushion cut lab grown diamond engagement ring is handcrafted in solid 14K or 18K gold, white, yellow, or rose, and certified by the IGI (International Gemological Institute). Our lab grown cushion diamonds are chemically, optically, and physically identical to earth-mined diamonds — grown sustainably, free of mining, conflict, and environmental destruction.

Our cushion collection spans every major setting style — from the hidden halo knife-edge cathedral solitaire and the V-gallery modernist solitaire, to pavé halos and pavé cathedral rings. Each ring is made to order in 1ct, 2ct, and 3ct with a physical IGI grading report and free, fully insured US shipping.

Questions & Answers

Everything about
cushion cut lab grown diamond rings diamonds

  • The cushion cut is a square or rectangular diamond shape with rounded corners and large facets. It combines the outline of a princess cut with the softer edges of an antique mine cut, producing exceptional fire and a distinctive warmth that rounds and brilliants cannot replicate.
  • 'Crushed ice' describes a cushion cut faceting pattern where the facets are smaller and more numerous, creating a scattered, sparkling effect that resembles crushed ice. Standard cushion cuts have larger facets and produce more distinct light reflections — both are beautiful, with different visual personalities.
  • Cushion cuts can appear similar in size to round diamonds of the same carat weight, but their larger surface area and distinct silhouette make them visually striking in ways rounds are not. Many buyers find the square outline makes the diamond appear bolder and more distinctive.
  • Cushion cuts work beautifully in halos (which amplify their size), cathedral solitaires (which elevate their architectural outline), and pavé settings (which add continuous sparkle around their edges).
  • Yes. Every cushion cut lab grown diamond sold by Trusamra includes a physical IGI grading report documenting cut, color, clarity, and carat weight.
  • All Trusamra cushion engagement rings are available in solid 14K and 18K gold in white, yellow, and rose — solid gold throughout, not plated.
