Extreme macro hero shot of [a sleek chess knight] crafted from premium clear optical cast glass, resting on a glossy reflective floor. Seamless studio environment with a cool, muted blue-gray gradient background. Lighting features broad diagonal soft light bands casting subtle soft-edged shadows, alongside vivid prismatic rainbow caustics and brilliant caustic light streaks fanning across the surface. The optical glass features smooth, razor-sharp edges, pristine clarity, minimal internal distortion, and delicate star glints. The subject fills roughly 90–95% of the frame, fully visible and uncropped, photographed in a luxury commercial product style.
