3 Carat E Color Lab-Grown Diamond

Make a timeless and radiant impression with a 3 carat E color lab-grown diamond. Celebrated for its near-colorless appearance and excellent light performance, E color diamonds are ideal for those who value pristine clarity and upscale beauty in premium engagement rings or fine jewelry.

What Is a Lab-Grown Diamond?

Lab-grown diamonds are authentic diamonds cultivated using cutting-edge technology in controlled lab conditions. Formed through HPHT (High Pressure High Temperature) or CVD (Chemical Vapor Deposition) methods, they are chemically, visually, and structurally identical to natural diamonds.

Lab-grown diamonds typically cost 30% to 50% less than mined alternatives, offering high quality at a better value—plus they’re a more ethical and eco-conscious option.

All RÊVE Diamonds’ lab-created gems are independently certified, with IGI or GIA being the most trusted grading authorities.
