A complete amethyst cluster rests on a dark stone shelf, lit by a single high window. Cool violet light glints off every crystal face while a faint matcha-green glow gathers in the shadows. Classical realist modelling gives the mineral real depth and weight, with delicate highlights tracing each facet. Purple leads the palette from first glance to last, and the light falls generously across the whole canvas, isolating the stone in quiet, academic stillness.
