Ultra-realistic ASMR video of a perfectly shaped green apple made entirely from transparent emerald-green glass, sitting on a dark wooden cutting board. The glass apple has realistic apple contours, a glass stem and glass leaf, glossy reflective surfaces, beautiful light refraction, and tiny internal reflections. A sharp knife slowly cuts through the glass apple, creating satisfying crystalline cracks and clean glass separation. Extreme macro close-up, slow motion, cinematic lighting, shallow depth of field, highly detailed glass textures, realistic reflections and refractions, satisfying ASMR aesthetic, no people, no talking, no music, only crisp glass cutting and delicate cracking sounds, 4K.
