The hardness of lab grown diamonds
The hardness of a diamond is measured using the Mohs scale of hardness, with diamonds rated as a maximum of 10, meaning they are the hardest known mineral.
Laboratory diamonds are produced using technologies that mimic the natural process of diamond formation, resulting in a crystal structure with a high hardness. Techniques such as Chemical Vapor Deposition (CVD) and High Pressure High Temperature (HPHT) make it possible to create very homogenouse diamonds with a high clarity and this contributes to their hardness.
Laboratory diamonds are therefore highly resistant to scratches and wear, just like natural diamonds. This characteristic makes lab diamonds attractive for a variety of uses, including in jewelry making and industrial tools.
