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 are indistinguishable, even by a trained gemologist.
The primary difference between lab-grown and mined diamonds is their origin. Mined diamonds are created under immense pressure and heat deep within the Earth, whereas lab-grown diamonds are produced using high pressure and temperature (HPHT) or chemical vapour deposition (CVD) in a controlled environment.
Lab-grown diamonds are typically 30 to 50 per cent more affordable than mined diamonds, making them a popular choice for those seeking a larger, high-quality diamond within their budget.
All Reve Diamonds lab-grown diamonds are certified by leading independent diamond grading laboratories such as IGI or GIA.
