Ethereal high-fashion mermaid in full VISONA-inspired style, sculpted from crystal glass and liquid sapphire. Ultra-translucent flowing fins with refractive highlights, prismatic edges, and shimmering caustic reflections. Body made of smooth crystalline surfaces with sapphire depth, glowing sub-surface scattering, and jewel-like textures. Hair formed from liquid glass strands drifting softly underwater, catching iridescent light. Dynamic fluid shapes, organic folds, and high-gloss surfaces. Surreal underwater atmosphere with floating particles, cinematic lighting, ultra-detail, 8K, luxurious and dreamlike aesthetic.
