Ultra-realistic 3D product render of a tall elegant crystal martini glass with a thin stem and wide conical bowl, perfectly centered against a smooth light gray studio background. The martini glass is filled with large transparent ice cubes with realistic cracks, trapped air bubbles, frosty edges, and melting water droplets. Detailed condensation forms naturally on the outer surface of the glass, with tiny beads of water running down the sides. The glass material is highly realistic with accurate light refraction, caustics, reflections, and subtle imperfections in the crystal surface. Professional studio lighting setup with softbox reflections, cinematic highlights, soft shadows beneath the base, and depth realism.
