Cushion Cut Engagement Rings

Named for its soft, pillow-like outline, the cushion cut blends a squared shape with gently rounded corners and exceptional fire — a romantic, slightly vintage look that has been popular for nearly two centuries. Cushions come in two faceting styles worth understanding before you buy: standard (larger, bolder flashes of light) and "crushed ice" (a shimmering, sugary sparkle). Both are represented in our collection so you can choose the personality you prefer. The cut is also known for holding colour well, making it a favourite in warmer yellow and rose gold settings. Every cushion here is an IGI-certified, conflict-free lab-grown diamond set in solid 10K–18K gold — timeless, forgiving, and full of character.
