A 5 carat oval cut lab-grown diamond offers the brilliance of a round cut in an elongated silhouette that flatters the finger and appears larger than its actual carat weight. Its soft curves and 56 to 64 facets create a romantic sparkle, making it a favourite for vintage-inspired and modern settings alike. At 5 carats, this is a substantial, statement-size diamond.
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.
