Synthetic sapphire has been used in watches for years. I also have an old Contax TVS digital camera that uses it . It is not new but does cost more than regular hardened glass.
it is Synthetic sapphire, very cheap. not the nature one.
it's a common manufacturing process developed a century ago. Nothing special, it's a required component for the phone production.
another sell gimmick from fruit co.
Poor Nokia, used so much sapphire on their 8800 series line..If only they had kept up
Good, as long as it does not increase the cost of phones. I get the point of it for the lens but not the screen. Just put a screen protector. It will scratch, possibly more often but you can just replace the protector after.

Sapphire is good stuff, very hard and scratch resistant, but impact resistance is not it's best side.

sapphire, precious stone. A transparent blue corundum, it is classified among the most valuable of gems. Sapphires are found chiefly in Thailand, India, Sri Lanka, and Myanmar and also in Australia and in the United States (in Montana). The sapphires from Kashmir are of a beautiful cornflower blue and are highly valued. The Sri Lankan varieties are paler; those from Montana have a metallic luster; and the Australian sapphires are of a dark blue shade approaching black. The terms yellow sapphire, purple sapphire, and green sapphire are used alternatively with Oriental topaz, Oriental amethyst, and Oriental emerald for other varieties of corundum. Like rubies of similar structure, some sapphires display a six-pointed star when cut to a cabochon (round-topped) shape and exposed to direct sunlight. Such star sapphires are usually obtained from Sri Lanka. Synthetic sapphires are made by the fusion of aluminum oxide, with titanium oxide added as a coloring agent.
