Polished Agate Cross Section on Lichen Bark

Sunlight falls through sheer curtains, casting soft, diffused patches across a polished agate slice resting on rough, lichen-covered bark. The stone reveals concentric bands of translucent orange, deep violet, and milky white, each layer distinct against the matte surface. Tiny green and grey lichen patches rest on the weathered wood, against the smooth, glass-like finish of the mineral. The dry season light creates gentle highlights along the agate's curved edge, showing the depth of the internal bands. Dust motes are absent, leaving only the sharp textures of stone and bark in clear focus. A thin line of shadow falls across the lower right corner where the wood grain meets the stone's perimeter.
