8 Carat Lab-Grown Diamonds

Carat Weight

8-carat diamonds make an extraordinary statement, perfect for engagement rings, necklaces, and high-end jewellery pieces.

Lab-Grown Diamonds

Lab-grown diamonds are genuine diamonds created in a laboratory rather than forming naturally in the Earth's crust. They possess the same physical, chemical, and visual properties as mined diamonds, making them indistinguishable, even to trained gemologists.

The only difference between lab-grown and earth-grown diamonds is their origin. Earth-grown diamonds develop under extreme pressure and temperature deep underground, whereas lab-grown diamonds are formed using High Pressure High Temperature (HPHT) or Chemical Vapour Deposition (CVD) methods in a controlled environment.

Lab-grown diamonds are typically 30 to 50 per cent more affordable than mined diamonds, allowing you to get a larger, high-quality stone within your budget.

All Reve Diamonds lab-grown diamonds are certified by leading independent grading laboratories, including IGI and GIA.
