3 Carat D Color Lab-Grown Diamond

Make a stunning and refined statement with a 3 carat D color lab-grown diamond. Prized for its flawless, icy-white hue, D color ranks at the top of the color scale, delivering unmatched brightness and visual appeal—perfect for high-end rings and fine jewelry lovers.

What Is a Lab-Grown Diamond?

Lab-grown diamonds are genuine diamonds made using modern technology in a controlled lab environment. They’re created using HPHT (High Pressure High Temperature) or CVD (Chemical Vapor Deposition) methods. These diamonds are chemically, optically, and structurally identical to mined ones. Choosing lab-grown gives you 30% to 50% savings compared to natural diamonds, along with the benefit of a more sustainable and conflict-free option.

At RÊVE Diamonds, every lab-grown diamond is independently certified—typically by IGI or GIA—ensuring quality and trust.
