3 Carat Oval Cut Lab-Grown Diamond

Make an elegant and radiant impression with a 3 carat oval cut lab-grown diamond. Celebrated for its elongated shape and timeless brilliance, the oval cut combines the fire of a round brilliant with a flattering silhouette—ideal for modern engagement rings and classic jewelry designs.

What Is a Lab-Grown Diamond?

Lab-grown diamonds are real diamonds, created in a high-tech lab using either High Pressure High Temperature (HPHT) or Chemical Vapor Deposition (CVD) methods. They are chemically, visually, and physically the same as mined diamonds—virtually indistinguishable, even to expert gemologists.

Lab-grown diamonds typically cost 30% to 50% less than natural stones and offer a more ethical and environmentally conscious alternative.

All of RÊVE Diamonds’ lab-grown diamonds are independently certified by trusted gemological labs such as IGI or GIA to ensure quality and transparency.
