Lapis, a female Russian Blue cat Jewelpet from Jewel Land, embodies the lapis lazuli jewel motif through her dark azure jewel eyes. Her physical form features a slender blueish-grey body with cyan inner ears, consistently accessorized by a gold collar bearing a tear-shaped lapis lazuli pendant and a gold beaded bracelet on her left front paw. This bracelet darkened to purple during corruption episodes. Her jewel charm manifests as a hexagon-shaped aqua blue item adorned with yellow beads and a central teardrop gem.

Personality-wise, she balances maturity with occasional snark, harboring a deep fascination for horoscopes and stargazing-based fortune-telling. Official narratives underscore her dual purpose: bestowing strong fortune upon humans and annihilating evil. When corrupted by Dian’s dark magic or the Red Moon’s possession, her demeanor twists toward cruelty and trickery—exemplified by capturing and tickle-torturing characters like Ruby, Sapphie, Chiari, and Ruruka.

Magically, Lapis wields two core abilities: granting potent luck to humans and destroying malevolent forces. Secondary skills include fortune-telling via devices such as the Jewel Pod and sensing moral alignments, like detecting Dian’s inherent evil upon their first encounter. These powers activate across varied scenarios, from predicting Ruby’s future during a sports festival to serving as a mystical bartender.

Her background spans multiple series. In the original Jewelpet, she belongs to the Jewel Eight group. Corrupted by Dian during the Jewel Games, she defeats King and joins Dian’s faction while retaining awareness of King’s affection. The corruption breaks when she acknowledges her care for King, leading to their escape and her subsequent aid to protagonist Rinko.

Later appearances diversify her roles: in *Jewelpet Twinkle*, she forecasts Ruby’s athletic outcomes and senses a powerful bond between Ruby and human partner Akari. *Jewelpet Kira☆Deco* depicts her as a bar owner for mature patrons like Coal, Io, and Kaiser, where her nurturing aura earns the nickname "Mama Lapis" from Blue. *Jewelpet Happiness* introduces a romantic subplot involving a human school nurse; their bond culminates in creating a Magic Gem after Lapis briefly succumbs to Red Moon possession. During this arc, her corrupted state includes capturing Ruruka Hanayama, though Ruruka helps restore her memories of the nurse’s love. She concludes with a cameo alongside Peridot, Jasper, Nix, and Luna in *Lady Jewelpet*.

Relationships critically shape her arc. Romantic ties include mutual feelings with King despite initial conflict under Dian’s influence, and a star-crossed bond with the school nurse, who marked his sail with a symbol later replicated on his lab coat. Her Kira☆Deco bartender persona reinforces maternal connections with patrons.

Trivia notes reference lapis lazuli’s historical significance as a semi-precious stone and the "Mama Lapis" epithet reflecting her mature roles. Descriptions of her powers vary seasonally, spanning evil purification, luck-bestowing, and destiny-seeing.
