About sapphire glass
SAPPHIRE CRYSTAL (sapphire glass) generally refers to synthetic sapphire, generally used in the manufacture of the watch glass.
It is resistant to wear with tungsten titanium alloys and high-tech ceramics. but sapphire materials can wear resistance and
withstand the strong impact, and some of the same or higher hardness of the material (e.g., millstone, sandpaper, nail, granite,
concrete wall, and floor, etc.) so sapphire glass are not likely to scratch the surface of these materials.
