Create a detailed 3D model of a magical wand designed for a young spellcaster. The wand should be slender and slightly twisted, made of enchanted wood like elder or willow. Add glowing runes etched along the shaft, and a gemstone tip — options like amethyst, ruby, or moonstone. Include subtle spark effects or magical aura swirling around it. The handle should be wrapped in velvet or dragonhide, with a charm or tassel dangling from the base. The design should feel mystical, elegant, and ready to cast powerful spells.
