Lab-grown diamonds are real diamonds created in controlled laboratory environments using advanced technology that replicates the conditions under which diamonds form naturally. They have the same essential chemical composition, crystal structure and optical properties as mined diamonds.
The International Gemological Institute (IGI) is an independent gemological organisation that grades and identifies diamonds. An IGI grading report provides detailed information about an individual diamond's characteristics and confirms whether it is laboratory-grown.
Carbon offers IGI-certified lab-grown diamonds, providing independent grading information about important diamond characteristics such as carat weight, colour, clarity and other identifying details, as stated on the relevant product or certificate.
The 4Cs of diamonds stand for Cut, Colour, Clarity and Carat. Together, these characteristics provide a widely used framework for understanding and comparing diamond quality.
