Yes, lab-grown diamonds are diamonds of the highest quality. That means they are optically, chemically, thermally and physically identical to mined diamonds, and are rated by the same “4Cs” – clarity, cut, colour and carat. Just like mined diamonds, they start out in the rough and are then meticulously crafted by skilled artisans to unleash the individual fire and beauty in each stone. The main difference between lab-grown diamonds and mined diamonds is that lab-grown diamonds are formed above ground, whereas mined diamonds are drawn from the earth.
