This Shugo Chara! Amulet Diamond figure stands poised with a confident stance, 180 mm tall, captured in a dynamic pose on a small decorative base. The costume features the character’s signature color palette: a white base with blue accents and crystal-like diamond motifs along the sleeves and chest, clear translucent parts for a jewel-like effect, a glossy finish, and precise sculpting of hair with flowing strands and ribbons. The eyes are bright turquoise with sparkles. The base includes a subtle Shugo Chara! insignia. The figure's cape or scarf flows as if blown by wind, giving a sense of movement. Painted shading emphasizes soft folds, edges, and metallic highlights on the gems.
