Phosphophyllite Shinsha, a collaboration by Uneri Kaidan, is a delicately sculpted figure that captures the gem's crystalline brilliance and fragile, yet determined, presence. The model presents Phosphophyllite with a slender, graceful silhouette, translucent teal-blue-green hues, and faceted surfaces that catch light from every angle. The hair and accessories resemble shattered crystals, meticulously carved to mimic shards caught in a gentle breeze. The pose conveys a moment of quiet resolve: one hand lightly raised as if ready to reveal hidden knowledge, the other braced for balance. The base mimics mineral terrain, enhancing the gemstone aesthetic and emphasizing the character's fragility and grace, with a soft glow that suggests inner light.

Phosphophyllite is one of the younger gems who begins with a nearly fragile heart and an insatiable curiosity. In Houseki no Kuni, Phosphophyllite is tasked with dangerous duties due to its brittleness, a contradiction that drives growth rather than resignation. Through encounters with other gems—each with their own skill and history—Phosphophyllite learns the value of knowledge, careful planning, and resilience. The journey involves choosing a role, enduring loss, and discovering that strength can come from kindness, adaptability, and a steady, patient pursuit of truth. The figure reflects this character arc, presenting Phosphophyllite at a pivotal moment where curiosity, resolve, and fragile beauty converge into quiet leadership.
