Kyocera has published a new video of its Sapphire Shield smartphone cover in action, pitting it against standard impact-resistant glass in a few drop and scratch tests. As you might expect, the sapphire cover fared much better than the glass. While the glass display was easily scratched and shattered using a piece of granite, the Sapphire Shield looked like it had just come out of the box.

The Sapphire Shield can currently be found on Kyocera’s Brigadier smartphone, which became available from Verizon last week. The phone is currently one of a few to sport a sapphire display, though it’s widely believed that Apple will be debuting such a device early next month.
