5 Carat Lab-Grown Diamonds

Carat Weight

5-carat diamonds make a bold statement, ideal for those seeking a large, impressive diamond for engagement rings, pendants, or bespoke jewellery pieces.

Lab-Grown Diamonds

Lab-grown diamonds are genuine diamonds created in a controlled laboratory environment rather than forming naturally beneath the Earth's surface. They possess the same physical, chemical, and optical properties as mined diamonds and are indistinguishable, even to trained gemologists.

The primary difference between lab-grown and mined diamonds is their origin. While mined diamonds take millions of years to develop under extreme pressure and heat deep within the Earth, lab-grown diamonds are produced using advanced High-Pressure High-Temperature (HPHT) or Chemical Vapour Deposition (CVD) techniques in a controlled setting.

Lab-grown diamonds offer exceptional value, typically being 30 to 50 per cent more affordable than their mined counterparts. This means you can purchase a larger, high-quality diamond within your budget.

All Reve Diamonds lab-grown diamonds are independently certified, with most being graded by IGI or GIA—two of the most reputable diamond certification laboratories worldwide.
