Unique Mechanical Properties
Sapphire as a material is extremely hard, having a Mohs hardness of 9. This is secondly only to the natural mineral Diamond, which has a Mohs hardness value of 10. As a result, it is also highly scratch-resistant, which makes it suitable for several industries. As compared to sapphire, glass has a hardness value close to 5.5.
