1 Carat Cushion Cut Lab Grown Diamonds
Discover the Perfect 1 Carat Cushion Cut Lab Grown Diamond
The Sweet Spot of Size, Brilliance, and Value
A 1 carat cushion cut diamond represents the ideal balance of visual presence and wearability, making it one of the most sought-after sizes for engagement rings and fine jewelry worldwide. At this carat weight, the cushion's distinctive pillow-like shape with soft, rounded corners is beautifully defined, showcasing the romantic silhouette that has captivated hearts for over 200 years. The larger facets create bold flashes of fire and that characteristic warm sparkle that cushion cuts are famous for. Our 1 carat lab grown cushion diamonds are created using advanced CVD and HPHT technology, producing stones that are physically, chemically, and optically identical to mined diamonds while offering up to 70% savings—allowing you to invest in premium color and clarity grades or exquisite settings.
Why 1 Carat is the Most Popular Choice
There's a reason 1 carat remains the most popular diamond size globally—it offers substantial visual impact without being overly large, making it perfect for everyday wear while still making a statement. A 1 carat cushion cut typically measures approximately 5.5-6mm across, providing excellent finger coverage and presence. At this size, you can clearly appreciate the cushion's soft curves, the interplay of light across its facets, and the exceptional fire that makes this cut so distinctive. Whether you prefer a square cushion (1.00-1.05 ratio) or slightly elongated cushion (1.10-1.20 ratio), 1 carat provides the perfect canvas to showcase the shape's romantic character.
IGI Certified Quality Across All Grades
Every 1 carat cushion diamond in our collection comes with IGI certification—the international standard for diamond grading trusted across all major markets. Our collection spans a comprehensive range of quality combinations, from premium D-F colorless grades with VVS clarity for those seeking absolute perfection, to excellent-value G-H near-colorless grades with VS clarity that appear flawless to the naked eye. Each certificate provides complete transparency on cut quality, color, clarity, carat weight, measurements, and proportions, giving you confidence whether you're shopping from Mumbai, Dubai, London, or New York.
Perfect for Engagement Rings and Beyond
A 1 carat cushion cut diamond is the quintessential engagement ring choice, offering that perfect combination of romantic vintage appeal and modern brilliance. The size works beautifully in classic solitaire settings that let the cushion shape shine, stunning halo designs that amplify the romantic aesthetic, elegant three-stone settings, and vintage-inspired designs that honor the cut's 19th-century heritage. Beyond engagement rings, 1 carat cushions make breathtaking pendants, statement earrings, and custom jewelry pieces. The soft corners provide durability for everyday wear while maintaining refined elegance.
