One application of synthetic sapphire is sapphire glass often called blue glass as sapphires are blue in color. Here glass is a layman term which refers not to the amorphous state, but to the transparency. Sapphire is not only highly transparent to wavelengths of light between 150 nm (UV) and 5500 nm (IR) (the human eye can discern wavelengths from about 380 nm to 750 nm[50]), but is also extraordinarily scratch-resistant. Sapphire has a value of 9 on the Mohs scale of mineral hardness.
