Rutile is depicted in a refined and luminous design that emphasizes her crystalline nature. The 1/10 scale figure is meticulously sculpted to resemble a faceted gemstone beneath soft, translucent skin tones. Her hair is rendered in a pale, icy tint that complements the gold-yellow facets of her body, with precise edge cuts to imitate crystal facets. The costume features slender, body-hugging armor plates and delicate joints, all painted with subtle shading to convey depth. Light catches the figure across the facets and through the transparent resin eyes, creating a shimmering, jewel-like presence. The base is a simple, clean platform with a stone-like texture that echoes her mineral origins, ensuring stability while letting Rutile remain the focal point.

In Houseki no Kuni, Rutile is one of the living gems who navigate the fragile balance between duty and self-discovery within a world threatened by lunar invaders. She is thoughtful and observant, often serving as a steady voice during crises and a careful strategist when plans must be formed quickly. Rutile’s interactions with fellow gems—such as Phosphophyllite, Diamond, and others—reveal her capacity for empathy, resilience, and quiet humor under pressure. As the saga unfolds, she learns to question strict roles and to seek a purpose beyond mere survival, forging friendships that define her true path and loyalty to the community.
