The Mirror

"Just...for...you...Steven!"

"The Mirror" is a magical, Gem-powered item that first appears in "Mirror Gem". Steven is given the mirror by Pearl to learn about Gem history and later discovers that a Gem, Lapis Lazuli, is trapped within the mirror. The mirror's glass surface shatters as Steven pulls out Lapis Lazuli's cracked gemstone, setting her free. The remnants of the mirror are discarded afterwards.

Appearance
An ornate design of silver-blue metallic material comprises the backing and handle of the mirror; Lapis' cracked gemstone was affixed to its back. The mirror itself is a round piece of blue reflective glass with a faint contour of an octagonal gemstone etched on its surface.

"Mirror Gem"
Pearl gives the mirror to Steven so he can learn about Gem culture and history; it is able to show its viewer any event it was present for since its creation. Pearl tells Steven they found the item at the Galaxy Warp. As Steven and Lapis begin communicating, she tells him she was purposely imprisoned within the mirror. Steven releases her by removing the gemstone from the back, shattering the mirror. The Crystal Gems' potential prior connection with Lapis and the mirror is currently unknown.

Trivia

 * The eight-point star on the mirror may be a reference to the Khatim Suleiman (خاتم سليمان), meaning Solomon's Ring. Islamic legends state that King Solomon captured Djinn with an eight-point star ring, similar to how Lapis was trapped inside the mirror.
 * Due to the way the remaining Crystal Gems were confused when Lapis blamed them for her being trapped in the mirror, it is possible that a past Crystal Gem trapped her.
 * Lapis' gem was apparently damaged after she was trapped, as the crack runs across the mirror's backing.
 * The symbol on the front of the Mirror is similar to the flare sent out of Peridot's Escape Pod..
