Are you looking to buy a lab-grown loose diamond or engagement ring? Select from the thousands of certified diamonds in our collection. Lab-grown diamonds are chemically, physically, and optically identical to mined diamonds — available at 50–70% less than the cost of a naturally mined stone.
A 3-carat Excellent Cut diamond is a refined and elegant option for engagement rings or bespoke jewellery. Expertly cut for symmetry and sparkle, it delivers intense brilliance and fire—ideal for those who value exceptional light performance and precision.
Lab-grown diamonds are real diamonds created in a laboratory setting, using either the High Pressure High Temperature (HPHT) or Chemical Vapor Deposition (CVD) process. They are physically, chemically, and visually the same as mined diamonds—so much so that even expert gemologists require advanced equipment to tell them apart.
Choosing lab-grown means saving 30% to 50% over the price of a natural diamond, all while making an environmentally conscious and ethical decision.
All REVE Diamonds’ lab-grown stones are independently certified, most commonly by IGI or GIA.
