3 Carat Round Cut Lab-Grown Diamond

Make a dazzling and timeless statement with a 3 carat round cut lab-grown diamond. Famed for its unmatched brilliance, perfect symmetry, and 360-degree sparkle, the round cut is a preferred choice for engagement rings and fine jewelry that never go out of style.

What Is a Lab-Grown Diamond?

Lab-grown diamonds are genuine diamonds created in controlled lab settings using High Pressure High Temperature (HPHT) or Chemical Vapor Deposition (CVD) technology. They are chemically, physically, and visually identical to mined diamonds—so alike that even expert gemologists need special equipment to differentiate them.

Choosing a lab-grown diamond can save you 30% to 50% compared to natural diamonds, making it an affordable, ethical, and eco-conscious choice.

All RÊVE Diamonds’ lab-grown stones are independently certified, primarily by IGI or GIA, for guaranteed quality and authenticity.
