This Phosphophyllite figure from Houseki no Kuni embodies the delicate beauty and inner strength of its titular gem. The sculpture presents Phos in a poised, almost ethereal stance, with a slender neck, gently angled head, and a luminous, faceted torso that resembles a cut gemstone. The pale mint-blue color catches light from every angle, revealing subtle gradients and tiny crystalline facets along the limbs and clothing. The base is crystal-clear and textured to resemble broken ice, giving the impression of a winter facet emerging from a frozen sea. The pose captures Phos' quiet curiosity and readiness to confront danger, while the flowing line of the dress and hair conveys a sense of movement even at rest. Small accessories or petals at the wrist are finished with meticulous precision, reflecting the brand's attention to detail. Overall, the piece radiates a gem-like aura that suits the character's themes of fragility and resolve.

Phosphophyllite, known as Phos, begins as the youngest and most fragile gem among the lunar-based sentinels. She is awkward, curious, and eager to help, yet her brittle form makes her an object of caution among peers. Throughout the series, Phos endures dramatic transformations in body and mind as she searches for meaning, information, and a place in a world that constantly reshapes itself. Her journey takes her beyond simple battles for survival into questions about identity, purpose, and what it means to grow up when every change could end in shattering. Along the way, Phos forms unlikely alliances, loses friends, and discovers a strength she never imagined. The character's arc blends vulnerability with resilience, turning a delicate figure into a symbol of perseverance, discovery, and the danger and beauty of change.
