Rocket proof glass?
Sapphire glass has a resistance of 2000 HV – 2X as much as mineral glass.
This means the glass stays in excellent condition for several years after purchase. Not only that but it adds value over time due to its strong frame.
The simplicity and shininess that come from this elegant piece of glass will make you look like an ambitious man who knows what he's doing in any realm of human endeavor.

Sapphire glass has a hardness of around 2000 HV – twice as much as mineral glass.Sapphire glass can therefore only be scratched by a few materials, including real diamond with 4,500 to 10,000 HV. For comparison: stainless steel comes to about 220 HV.
