6 Carat Lab-Grown Diamonds

Carat Weight

A 6-carat diamond is an impressive and luxurious choice, perfect for engagement rings, necklaces, and statement jewellery.

Lab-Grown Diamonds

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

The only difference between lab-grown and mined diamonds is how they are formed. Mined diamonds develop 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 Vapor Deposition (CVD) in a controlled lab environment.

Lab-grown diamonds are typically 30 to 50 percent more affordable than mined diamonds, making them a highly popular choice for those looking for 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.
