A 1-carat E colour diamond is a sophisticated choice for elegant jewellery and engagement rings. Near colourless with minimal warmth, E colour diamonds offer stunning brilliance and clarity—ideal for those seeking exceptional beauty and value in a timeless style.
Lab-grown diamonds are real diamonds, created in cutting-edge laboratories that replicate the earth’s natural conditions. They share the same chemical and physical properties as mined diamonds but cost significantly less. With savings of up to 50%, you can select a higher-quality or larger stone—without compromising ethics or aesthetics.
At RÊVE Diamonds, each lab-grown diamond is independently certified—usually by IGI or GIA—ensuring full confidence and transparency in every selection.

Prices typically range from £800 to £3,800 depending on cut, clarity, and certification.

Depth: 3.7 mm – 4.1 mm (avg. 3.9 mm)
Cut quality and proportions affect the final size and appearance.
