Lapis Lazuli 青金石

Lapis Lazuli, or Lapis for short, is a member of the Crystal Gems. During her alignment with the Gem Homeworld, she was caught in the crossfire of The Rebellion and got poofed by Bismuth so Homeworld mistook her for one of the Crystal Gems and imprisoned her within a magical mirror. She would remain in the mirror for thousands of years until she eventually convinced Steven to free her. Once she returned to Homeworld she was forced back to Earth by Peridot and Jasper, the latter of whom she fused with into Malachite to imprison and take her anger out on. After she unfused and decided she had no other choice but to live on Earth, as she trapped a highly-regarded soldier, she lived at The Barn with the reformed Peridot until the threat of another war became a reality. She left Earth and took the Barn with her to the Moon until Steven found her and convinced her to come back but she decided to leave the Moon after he had another vision of The Great Diamond Authority. However, she returned to Earth to fight against the Diamonds in "Reunited" becoming a Crystal Gem in the process. She made her debut in "Mirror Gem".
