Laboratory-grown diamonds are made of pure carbon, just like natural diamonds. The chemical composition of lab-grown diamonds is identical to that of diamonds mined from the Earth's crust. Both types of diamonds are composed solely of carbon atoms arranged in a crystal lattice structure, which gives them their hardness, brilliance, and other characteristic properties.
The process of creating lab-grown diamonds involves providing a carbon source, typically in the form of graphite, and subjecting it to conditions that simulate the natural diamond-growing environment, such as high pressure and high temperature (HPHT) or chemical vapour deposition (CVD). Under these conditions, carbon atoms come together and form a crystal lattice, resulting in the growth of a diamond.
Due to their pure carbon composition and the same crystal structure as natural diamonds, lab-grown diamonds are physically, chemically, and optically identical to mined diamonds. As a result, they are considered real diamonds and are indistinguishable from natural diamonds without specialised equipment.
