Welcome to Rêve Diamonds, your trusted GIA certified diamond dealer in London. We specialise in providing the finest wholesale diamonds, offering you unparalleled quality at unbeatable prices.
A 7 carat Excellent cut lab-grown diamond reflects the vast majority of light entering the stone, delivering outstanding brilliance one small step below the Ideal grade. It's a popular choice for buyers who want exceptional sparkle at a more accessible price. A 7 carat stone of this kind is a rare, dramatic centrepiece — most jewellers handle only a handful of loose diamonds this size each year.
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.

Prices typically range from £8,840 to £38,500, depending on colour and clarity alongside the Excellent cut grade.
Excellent cut means the diamond's proportions and finish are graded just below Ideal, still returning the great majority of light for outstanding brilliance.
Most people cannot tell an Excellent cut diamond apart from an Ideal cut diamond by eye, making Excellent one of the best value cut grades.
