fantasy crystal sword 3d model

Create a single low poly fantasy crystal spear for use as a game asset, based closely on the reference image. Keep the overall silhouette, proportions, and decorative placement similar to the original design, but simplify small details for efficient game use. The weapon has a long slim black metallic shaft with a subtle spiral or twisted shape and a faint icy-blue glowing line wrapping around it. At the top, create a faceted diamond-shaped blue crystal spearhead with clean sharp edges, attached with a simple gold metal collar. Add simplified gold wire decoration and a small hanging chain with a few blue crystal gems. At the lower end, create a feather-like layered ornament using simplified black metal blades with blue crystal tips, plus a few small blue gem accents and gold ring details. Use low poly clean geometry, optimized shapes, readable forms, and a game-ready structure. Keep materials separated into black metal, gold metal, and blue crystal. Make it centered, isolated, and easy
