Lab-Grown Diamonds

Lab-grown diamonds are genuine diamonds created in a laboratory under controlled conditions rather than deep within the Earth's crust. They are physically, chemically, and optically identical to mined diamonds and are indistinguishable, even to a trained gemologist.

The only difference between lab-grown and earth-grown diamonds is their origin. While natural diamonds form under extreme pressure and heat deep within the Earth, lab-grown diamonds are created using High Pressure High Temperature (HPHT) or Chemical Vapour Deposition (CVD) processes in a controlled environment.

Lab-grown diamonds are typically 30 to 50 per cent more affordable than their earth-grown counterparts, making them an excellent choice for those seeking a larger, high-quality diamond within their budget.

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