A close-up shot shows a roughly cut, dark-colored rock resting on a brown surface. A hand enters the frame from the upper right, holding a white, rectangular "UV LAMP" device. The UV lamp shines a blue-purple light directly onto the rock, causing various sections of the rock to fluoresce in vibrant shades of blue, pink, and hints of green. The hand slowly moves the UV lamp across the rock, highlighting different areas and their distinct fluorescent responses.
