3 Carat Emerald Cut Lab-Grown Diamond

Make a sleek and timeless statement with a 3 carat emerald cut lab-grown diamond. Renowned for its elongated lines, step-cut facets, and clean elegance, the emerald cut is a top choice for engagement rings and high-end jewelry that radiates grace and sophistication.

What Is a Lab-Grown Diamond?

Lab-grown diamonds are real diamonds formed in a lab environment using either the High Pressure High Temperature (HPHT) or Chemical Vapor Deposition (CVD) technique. They are chemically, physically, and visually identical to mined diamonds—so similar that even gemologists need advanced equipment to detect the difference.

Lab-grown diamonds typically cost 30% to 50% less than natural ones, making them a smart, ethical, and eco-friendly alternative.

All RÊVE Diamonds' lab-created stones are certified by IGI or GIA, ensuring transparency and quality you can trust.
