3 Carat Radiant Cut Lab-Grown Diamond

Make a bold and brilliant statement with a 3 carat radiant cut lab-grown diamond. Featuring cropped corners and a dazzling facet pattern, the radiant cut combines the shape of an emerald with the fire of a round brilliant—perfect for those seeking sparkle with a modern edge in engagement rings or fine jewelry.

What Is a Lab-Grown Diamond?

Lab-grown diamonds are real diamonds grown in a laboratory using High Pressure High Temperature (HPHT) or Chemical Vapor Deposition (CVD). They are chemically, visually, and structurally identical to natural diamonds—so similar that even professional gemologists need advanced tools to differentiate them. Choosing a lab-grown diamond offers 30% to 50% savings over mined diamonds, with the added benefit of being an ethical, eco-conscious choice.

At RÊVE Diamonds, all lab-grown diamonds are independently certified by IGI or GIA—two of the most respected names in the diamond industry.
