Photorealistic Infinity Stone in a Robot Factory

Photorealistic, cinematic close-up of a single Infinity Stone resting in a precision cradle inside a sprawling robot factory. A sea of chrome and brushed steel, with robotic arms, conveyor belts, and hydraulic pistons. The gemstone glows with inner energy, its color a vivid hue (red, blue, green, yellow, orange, or purple) that pulses and reflects off nearby metal surfaces. The stone sits behind a transparent protective chamber lined with etched circuitry; nanoscopic circuitry and fine cables shimmer around the cradle. Dust motes, sparks, and wisps of steam float in cool blue ambient light, giving depth and atmosphere. Shot with shallow depth of field, ultra-detailed facets catching light, subtle chromatic aberration, and realistic metal reflections to convey awe and power as the factory hums with silent energy.
