Lab-Grown Diamonds
Lab-grown diamonds are real diamonds created in a controlled laboratory environment rather than forming naturally beneath the Earth's surface. They have the same physical, chemical, and optical properties as mined diamonds, making them indistinguishable—even to trained gemologists.
The primary difference between lab-grown and earth-grown diamonds is their origin. Earth-grown diamonds develop under extreme pressure and temperature deep underground, whereas lab-grown diamonds are produced using high pressure and high temperature (HPHT) or chemical vapour deposition (CVD) in a lab.
Lab-grown diamonds are typically 30 to 50 per cent more affordable than mined diamonds, making them an excellent choice for those seeking a larger, high-quality stone within budget.
All Reve Diamonds lab-grown diamonds are certified. Most are graded by IGI or GIA, the most respected independent diamond certification authorities.
