Desert Glass

The "Desert Glass" is a magical item that made its first appearance in "Steven's Lion".

About
The Desert Glass is a green gemstone embedded in a red pillow. For an unknown reason it became aimless, and now creates pillars and walls randomly. When placed on sand it creates a sandstorm and a fortress to protect itself. The Crystal Gems retrieved it from a desert, not knowing that the glass had a Lion guardian. Amethyst decided to hold on to it because she was the one who stopped it. Because Amethyst failed to contain it immediately, Steven accidentally set it off in the sand near the Crystal Temple. After Lion and Steven recovered it, the Desert Glass was finally contained by Pearl.

Trivia

 * Pearl is the only other Gem shown to have psammokinesis.
