Why Sapphire
A premium material certified by GIA.
Sapphire is a precious gemstone with exceptional hardness right behind diamond. Synthetic sapphire has been used on premium watches, iPhone fingerprint sensor and many other areas that require durability. Our sapphire crystals are grown in furnaces that previously used by Apple.
Extremely scratch-resistant
Sapphire is at level 9 on the Mohs hardness scale, which means sapphire is scratch proof to most minerals around us including sand, rock and concrete. Our sapphire screen protector will stay pristine when scratched by sandpaper.
The smoothest protector you can get.
We spend around 120 hours polishing each piece of sapphire protector, the final Chemical Mechanical Polishing (CMP) gives it a perfectly smooth surface that’s impossible for tempered glass. Sapphire is almost twice denser than glass (3.98 g/cc VS 2.7 g/cc).
Well worth the money.
This is the most premium screen protector you can possibly get. A piece of sapphire screen protector requires a total of 30 day to manufacture, with 21 days for crystal growth. This entire process is labor and energy intensive, the manufacture cost of sapphire is 30-50 times more than tempered glass protectors. We use equipment came from Apple’s partner, with world-leading technologies involved.

About Hardness

When we search for screen protectors online, the word “9H” pops up frequently. You might have been wondering, as a measure of hardness, how hard is “9H”?

In fact, “9H” is a misleading advertisement because it’s defined according to the pencil hardness scale. Obviously, graphite will not be harder than glass.

The Mohs scale is a qualitative ordinal scale characterizing scratch resistance of various minerals through the ability of harder material to scratch softer material. The Mohs scale defines talc as 1, diamond as 10. Sapphire sits on level 9 on this scale, which means it can resist scratches from sand, rock and concrete. Our sapphire screen protector will stay pristine under extreme environment.

Replacement purchase for damaged sapphire.

We don’t have warranty for damaged products. Sapphire will crack like glass. High hardness level doesn’t mean crack proof. We only promise that the product is made from 99.99% pure synthetic sapphire, with scratch protection up to Mohs 9.

We understand that sapphire is much more expensive than average products. We now provide a 30% off replacement purchase for damaged ones. You will be required to mail the damaged one back to us to be eligible for the discount (shipping will be free if you live in the US). Please see details on the product detail page.

What is the difference between 9H and Mohs 9?

9H is taken from the pencil hardness scale, which is a marketing fluff.

Mohs 9 is the hardness of corundum, right below diamond on the Mohs scale.

Although 9H is on the top of the pencil scale, a 9H pencil can never scratch any glass because it’s at around level 3 on the Mohs Scale. Knives or keys are below the hardness of glass (6), which means they won’t scratch glass either. 

Do you guys make sapphire protectors for iPad?

No, the difficulty level is positively correlated to the size of the screen, making sapphire protector of that size will be very expensive.

Sapphire screen protectors for Android phones?

We will do that if we find one that works with sapphire. We currently don’t have sapphire screen protector for android phones because most of them have large curves on the screen. Unlike glass, sapphire cannot be bent under heat because sapphire melts at 2050 degree Celsius. iPhones are ideal because the entire display area is completely flat.

What is the thickness of the sapphire screen protector?

0.23 mm

Is the installation easy enough to do at home?

Yes, we have detailed tutorial videos about the installation of all products. For each sapphire screen protector there is a precise installation frame in the package. If the result is not satisfying, we provide one free replacement (shipping included) if you live in the US.
