New scratch test video suggests iPhone 6 front panel may not be sapphire

The consensus thus far has been that the iPhone 6 will feature a sapphire-covered display. Apple recently opened a plant to produce large amounts of the material, and we’ve seen videos depicting purported iPhone 6 panels as virtually indestructible.

Today a new test video suggests that iPhone 6 front panel may not be sapphire. In the clip, YouTube veteran Marques Brownlee puts the panel to the test using Mohs scale of mineral hardness…

While not necessarily scientific, these types of torture tests are a ton of fun to watch, especially for anyone who loves to see just how much any piece of equipment can take when it comes to physical abuse. While watching knives, nails, keys, change, and other hard items get scraped against the sapphire display is one thing, we live in an era where the majority of our smartphone displays will survive those kinds of tests every single day of the week. Corning Gorilla Glass is well known for being quite durable — but what we’re expecting from Apple’s rumored sapphire glass display is something else entirely.

As Brownlee explains, the Mohs scale goes from 1-10, with 10 being the hardest. Minerals can scratch anything below it, but they can’t scratch anything above it. A steel knife is rated at a 5.5, Gorilla Glass 3 is a 6.8, and sapphire crystal glass is rated a 9.

We’re probably going to see several more torture tests for the iPhone 6′s sapphire crystal display, especially as the leaks continue to happen all over the world. Unfortunately, we won’t be able to tell what type of display Apple finally decides on until they officially announce the new device. While it helps that some experts are certain Apple will use the durable panel, anything is possible at this point.
