7 Carat Lab-Grown Diamonds

Carat Weight

A 7-carat diamond is a statement piece, perfect for those looking to make a lasting impression. These diamonds are ideal for engagement rings, necklaces, or luxury jewellery pieces.

Lab-Grown Diamonds

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.
