Geode Cross Section Beside Dust on Lyon Window

Soft raking light from a Lyon window illuminates a polished geode cross-section resting on a glass pane edged with delicate frost. The stone reveals concentric bands of amethyst and quartz in sharp detail, while tiny dust motes cluster along the mineral's rough outer rim. Early autumn light casts long, slender shadows across the crystalline interior, highlighting the jagged texture of the crystal points. Frost crystals form intricate, feathery patterns along the glass edge, against the smooth, waxy luster of the geode's cut face. The shallow depth of field blurs the distant cityscape, keeping focus entirely on the interplay between the trapped dust and the mineral structure. One dust particle rests precisely on the edge of a quartz cluster, catching the morning glow.
