Hoda iPhone 12 Pro 6.1" Sapphire Lens Protector, Silver (3PCS)
Sapphire is ruby under the jewelry class (except red rubies), general terms for other colored corundum stones, the main component is alumina. The artificial sapphire crystals used by Hoda are grown by heat exchange, growing into a crystal after 11 processing processes, total time spent 500 hours, to make your sapphire protective stickers.
Hoda Sapphire has up to 9 grades of hardness, just a grade before diamonds. It is near to impossible to scratch sapphire glass. The anti-reflection coating increases light transmission and contrast by reducing light reflection keeping your photo quality like without it. Hoda Sapphire glass is anti-fingerprint and is easy to clean.
While acrylic and sapphire both have pros and cons—and their own fans—today, most modern luxury watches exclusively use sapphire crystal. With better technology, Rolex changed from Acrylic to Sapphire Crystal.
