Moreover, the hardness of sapphire glass is second only to that of diamond, which will make the camera better protected and not easy to be scratched or corroded, so that the camera's photographing function will not be affected by these factors.

Its hardness is second only to diamond, equivalent to 7 times that of steel. Sapphire glass ≠ Natural sapphire.
