6 Carat Lab-Grown Diamonds

Carat Weight

A 6-carat diamond makes a bold statement, perfect for engagement rings, necklaces, and high-end jewellery pieces.

Lab-Grown Diamonds

Lab-grown diamonds are real diamonds created in a laboratory rather than being formed naturally within the Earth's crust. They are physically, chemically, and visually identical to mined diamonds and are indistinguishable even to a trained gemologist.

The key difference between lab-grown and mined diamonds is their origin. Mined diamonds form under extreme pressure and temperature deep beneath the Earth's surface, while lab-grown diamonds are created 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, making them an excellent choice for those seeking a larger diamond within their budget.

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