I guess many of us are confused between Sapphire Crystal and Sapphire Glass.
Sapphire Crystals are naturally occurring elements - like diamonds, and are indeed quite hard - next to diamonds. However Sapphire Crystals are rare to find (when compared to their demand!). Amongst the ones available, some of them contain 'impurities' (heard of blue sapphires? Yeah those are sapphire crystals with impurities) and the process to remove the impurities is difficult and almost impossible on such a large scale. Hence sapphire crystals are not malleable - certainly cannot be used to make glass sheets/screens.
Sapphire Glass on the other hand is synthetic. Since they duplicate the atomic structure of Sapphire Crystal they can be very hard and thus resist scratches. But being made into glass sheets also makes them
relatively more fragile ('relatively' being the key word here). Maybe that's one of the reasons why it is taking so long for Apple in implementing them in their phone screens I guess (and maybe costs too? I'm not sure there). Imagine stress endurance level of a watch glass with less surface area and a 4'' phone screen with a more surface area - highly unequal; phone screen thus being comparatively fragile.
Coming back to the topic, Sapphire Glass is almost as hard as Sapphire Crystal but is
not Sapphire Crystal (hence very very difficult to scratch but
not impossible). But dear OP, if
that is your camera ring then I'm curious to see the rest of your device
P.S. Whoops! Too long! Sorry! But I hope
somebody will read this.
