Cushion Cut Lab-Grown Diamond Rings

The cushion cut has been a symbol of romance for over two centuries — a softly rounded square with brilliant faceting that produces a warm, pillow-like glow. It carries vintage charm while feeling completely modern, which is why it remains one of the most requested diamond shapes for engagement rings. Every cushion cut lab-grown diamond at NYX Jewel is IGI certified and selected for exceptional fire and light return. Available in halo, hidden halo, solitaire, and pavé settings in 14K or 18K solid gold. Free shipping, 30-day returns, and lifetime warranty.
