A 1-carat G colour lab-grown diamond offers an ideal balance of quality and value. With its near-colourless grade, it provides a bright, natural appearance that looks stunning in any metal setting. G colour diamonds are highly sought after for engagement rings thanks to their radiant sparkle and refined look without the premium price of colourless stones.
Lab-grown diamonds are authentic diamonds cultivated in advanced laboratories under controlled conditions that mirror those deep within the Earth. They share the same atomic structure and brilliance as mined diamonds, yet offer an ethical and environmentally conscious alternative.
At RÊVE Diamonds, our lab-grown diamonds are certified by respected institutions such as IGI and GIA, guaranteeing genuine quality, precise grading, and exceptional beauty.

Prices generally range between £500 and £2,500 depending on the diamond’s cut, clarity, and certification.

Diameter: 6.3 mm – 6.6 mm (average 6.5 mm)
