Starlight Blade

Apply a high-quality, stylized magical texture to this sword. The blade should have a smooth, polished crystal surface with a soft iridescent gradient that shifts between pale blues, pinks, purples, and frosty whites. Add faint internal glow and subtle sparkling particles inside the blade to enhance a celestial winter aesthetic. The guard should be shaped as a bright star, emitting a warm white glow with clean, sharp edges. Give the star a semi-translucent crystal texture with strong luminance at the center and soft bloom around the points. The handle should have wrapped white leather with a matte finish and slight wear, contrasted with small decorative ice-crystal clusters that look sharp, faceted, and reflective. Add light frosted edges to the leather and gentle sparkle to the crystals.
