1.2 Carat Lab-Grown Diamonds

Carat Weight

A 1.2-carat diamond is an excellent choice for an engagement ring, offering a striking presence while remaining practical for everyday wear.

Lab-Grown Diamonds

Lab-grown diamonds are real diamonds created in a laboratory rather than deep within the Earth's crust. They share the same physical, chemical, and optical properties as mined diamonds and are indistinguishable, even to a trained gemologist.

The key difference between lab-grown and earth-grown diamonds is their origin. While mined diamonds form naturally under high pressure and temperature deep underground, lab-grown diamonds are produced using High Pressure High Temperature (HPHT) or Chemical Vapour Deposition (CVD) methods in controlled environments.

Lab-grown diamonds are typically 30 to 50 per cent more affordable than mined diamonds, allowing you to purchase a larger or higher-quality diamond within your budget.

All Reve Diamonds lab-grown diamonds are certified, with most assessed by IGI or GIA—two of the most respected independent diamond grading laboratories.
