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 4 carat radiant cut lab-grown diamond combines the elegant rectangular outline of an emerald cut with the intense sparkle of a round brilliant. Cropped corners and over 70 facets give it exceptional fire, making it a versatile choice for both classic and modern settings. 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.
