This figure presents Phosphophyllite with a poised, contemplative stance that captures their gentle, curious nature from Houseki no Kuni. The bust and limbs are sculpted to emulate the crystal facets of a gemstone, with clear icy blue and pale teal hues that suggest translucence and fragility. The surface finish alternates between glossy facets and satin skin textures to imitate the way light travels through a real gem. The hair is rendered as slender crystalline shards that catch the light, while tiny accessories and the base mimic mineral rock. The overall silhouette is elegant and reflective of Phos's evolving identity throughout the series.

Phosphophyllite begins as a newly awakened, fragile gem who lacks a clear role in the Lustrous world. This character’s arc centers on the search for purpose, the temptation to withdraw, and the painful lessons learned through encounters with other gems and the harsh realities of constant threat. Phos evolves from a curious, earnest apprentice into a more complex figure who questions traditions, seeks knowledge, and endures injuries that force growth. The narrative emphasizes resilience, adaptability, and the delicate balance between strength and vulnerability that define Phosphophyllite's path. This figure captures that inner journey in sculptural form.
