1 Carat Excellent Cut Lab-Grown Diamond

A 1 carat Excellent Cut diamond is crafted with meticulous precision to maximise its sparkle and light reflection. The result is an elegant and radiant diamond, ideal for engagement rings and timeless fine jewellery. Its balance of symmetry and fire makes it one of the most sought-after cuts.

What Is a Lab-Grown Diamond?

Lab-grown diamonds are authentic diamonds formed under controlled laboratory conditions using either the High Pressure High Temperature (HPHT) or Chemical Vapour Deposition (CVD) process. They are identical to mined diamonds in structure, composition, and brilliance—indistinguishable without advanced testing tools.

Opting for a lab-grown diamond saves you 30%–50% compared to natural stones, while also supporting ethical and sustainable jewellery practices.

Every RÊVE Diamonds lab-grown diamond is independently graded and certified by IGI or GIA for full transparency and quality assurance.
