“Which is why it is sealed in this case made of Clearstone, the hardest substance known to human. Impenetrable by any living being.”
Dr. Saunders to the ninja and Wu, "Day of the Departed"

Clearstone is the hardest substance known to man.

History

Day of the Departed

Dr. Saunders tells the ninja that the case for the Yin Blade is made of solid Clearstone. Cole is able to reach through the clearstone and grab the Yin Blade; because he's a ghost.

Powerless

When the ninja try to get a Scroll of Forbidden Spinjitzu, they can't open the case. Cole notes that it's probably Clearstone, but that's not clear, because Nya found that the case could be easily opened.
