Sapphire Crystal

Nearly impossible to scratch, the sapphire crystal lens is as hard and clear as a gemstone. There are only a few materials known to the world that can scratch it.

Sapphire Crystal

Scratch-resistant

Sapphire is the hardest crystal available. Given its hardness it is near impossible to scratch, however, it can be prone to shattering if subjected to a heavy impact. Its scratch resistance is very desirable and as such there is a higher cost to sapphire versus other crystals.
