Lab-grown diamonds are real diamonds created in a controlled laboratory setting rather than forming naturally within the Earth's crust. They are physically, chemically, and visually identical to mined diamonds and cannot be distinguished even by a trained gemologist.
The primary difference between lab-grown and earth-grown diamonds is their origin. Mined diamonds develop under extreme pressure and temperature beneath the Earth's surface, whereas lab-grown diamonds are created using high pressure and high temperature (HPHT) or chemical vapour deposition (CVD) methods in a laboratory.
Lab-grown diamonds are typically 30 to 50 per cent more affordable than mined diamonds, making them a popular choice for those wanting 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 reputable independent diamond grading institutions.
