A 4 carat oval cut lab-grown diamond combines the brilliance of a round cut with an elongated silhouette that flatters the finger and looks larger than its actual carat weight. Its soft curves and 56 to 64 facets create a warm, romantic sparkle, making it a favorite for vintage-inspired and modern settings alike. At 4 carats, this is a substantial, statement-size diamond.
Lab-grown diamonds are real diamonds created using either the High Pressure High Temperature (HPHT) or Chemical Vapor Deposition (CVD) method in a lab. These stones share the same physical, chemical, and visual properties as mined diamonds—only their origin differs. Even trained gemologists require special tools to tell them apart.
Choosing lab-grown means saving 30% to 50% over the cost of natural diamonds while making a sustainable and ethical choice.
All Rève Diamonds' lab-grown diamonds are independently certified, typically by IGI or GIA.
