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.
Make a soft yet striking statement with a 3 carat cushion cut lab-grown diamond. Loved for its pillow-like shape, romantic appeal, and antique-inspired brilliance, the cushion cut combines rounded corners and larger facets that maximize sparkle. Ideal for vintage settings or modern halo styles, it's a favorite for engagement rings and fine jewelry.
Lab-grown diamonds are real diamonds created using either the High Pressure High Temperature (HPHT) or Chemical Vapor Deposition (CVD) method in a lab. These stones share the same physical, chemical, and visual properties as mined diamonds—only their origin differs. Even trained gemologists require special tools to tell them apart.
Choosing lab-grown means saving 30% to 50% over the cost of natural diamonds while making a sustainable and ethical choice.
All REVE Diamonds’ lab-grown diamonds are independently certified, typically by IGI or GIA.
