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 to a trained gemologist.
The key difference between lab-grown and earth-grown diamonds is their formation. Mined diamonds develop under extreme pressure and temperature below the Earth's surface, while lab-grown diamonds are produced using high pressure and 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 an attractive option for those looking for a larger, high-quality diamond within their budget.
All Reve Diamonds lab-grown diamonds are certified. Most are graded by IGI or GIA, two of the most respected independent diamond grading institutions.
