A lab-grown diamond is prepared in the lab in contrast to mined diamonds. They are grown from tiny seeds of carbon with extreme pressure and heat in a controlled environment.

Lab-grown diamonds are both cost-effective and have a positive impact on the environment in comparison to naturally mined diamonds. Lab diamonds undergo the same processing as mined diamonds do and are graded against the same 4Cs of diamond certification.

As these diamonds are grown in a controlled environment, the processes used for lab-created diamonds are extremely safe and pose no threat to the people working on them. As a result, these diamonds are not only sustainable but are also safe for miners.
