5 Carat Cushion Cut Lab-Grown Diamond

A 5 carat cushion cut lab-grown diamond pairs rounded corners with larger facets for a soft, pillow-like silhouette and warm, romantic brilliance. Its antique-inspired shape has made it a lasting favorite for vintage and halo-style engagement rings. At 5 carats, this is a substantial, statement-size diamond.

What Is a Lab-Grown Diamond?

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 Rève Diamonds' lab-grown diamonds are independently certified, typically by IGI or GIA.
