3 Carat Princess Cut Lab-Grown Diamond

Make a striking and contemporary statement with a 3 carat princess cut lab-grown diamond. Known for its square shape and brilliant faceting, the princess cut is a modern favorite for engagement rings and luxury jewelry, blending sharp elegance with radiant sparkle.

What Is a Lab-Grown Diamond?

Lab-grown diamonds are real diamonds created in a lab environment, using High Pressure High Temperature (HPHT) or Chemical Vapor Deposition (CVD) techniques. These diamonds are physically, chemically, and optically identical to mined diamonds—so much so that only specialized instruments can detect the difference.

Choosing a lab-grown diamond offers savings of 30% to 50% compared to natural diamonds and supports an ethical, eco-conscious approach to fine jewelry.

All REVE Diamonds’ lab-created stones are independently certified, typically by IGI or GIA.
