About This Stone
Black Agate displays a composite surface composed of rounded nodular cross-sections set within a dark, opaque matrix. The individual agate formations exhibit concentric rings that transition from charcoal perimeters to pale quartz and translucent grey centres.
The surface presents tonal variation ranging from deep black and smoky obsidian to warm beige and milky white crystal cores. Interlocking circular boundaries and fine crystalline zoning create a continuous, multi-tonal aggregate pattern across the slab face.
