The Agate Side Table from Phillips Collection showcases geological artistry formed across millennia. Each cross-sectioned stone slice reveals concentric banding and color concentrations that remained hidden during the stone's formation deep within volcanic rock. The patterns vary dramatically from piece to piece, with some displaying bold contrasts while others show subtle tonal shifts. Light interacts with the stone's translucent qualities, creating depth and revealing internal structures that change with different illumination. The metal base elevates each disc, allowing the stone's characteristics to remain visible from multiple angles rather than obscuring the edges.
