A 10 carat cushion cut lab-grown diamond pairs rounded corners with larger facets for a soft, pillow-like silhouette and warm, romantic brilliance. Its antique-inspired shape has made it a lasting favourite for vintage and halo-style engagement rings. A 10 carat diamond of this kind is exceptionally rare, and is typically sourced to order rather than held in everyday stock.
Lab-grown diamonds are real diamonds, produced in high-tech labs that replicate natural geological conditions. They match mined diamonds in chemical composition, physical properties, and optical brilliance — the only difference is how they're formed. Lab-grown diamonds offer excellent value, often costing 30% to 50% less than mined diamonds of the same quality.
At Rêve Diamonds, we offer a wide range of lab-grown diamonds that are certified by leading gemological institutes such as IGI or GIA, ensuring authenticity and quality with every purchase.
