3 Carat Ideal Cut Lab-Grown Diamond

A 3 carat Ideal Cut diamond delivers exceptional sparkle and balance, making it a remarkable choice for engagement rings or bespoke fine jewellery. With precise proportions that reflect maximum light, it offers intense brilliance—perfect for those who appreciate both beauty and precision.

What Is a Lab-Grown Diamond?

Lab-grown diamonds are genuine diamonds created in laboratory conditions using High Pressure High Temperature (HPHT) or Chemical Vapor Deposition (CVD) methods. Physically and chemically identical to mined diamonds, they are so alike that only expert tools can distinguish them.

Lab-created diamonds cost 30% to 50% less than mined diamonds and are the ethical, eco-conscious alternative.

Each RÊVE Diamonds lab stone is independently graded and certified by IGI or GIA.
