A single, continuous spiral groove carved into the tile surface, starting from the center and expanding outward in a smooth, logarithmic curve. The groove is uneven in width and depth, with rough, eroded edges exposing layers of rust brown and hints of oxidized green beneath the surface. The spiral is slightly off-center, adding organic imperfection.
A fine, irregular pattern of tiny speckles, micro-cracks, and subtle color variations covering the entire tile surface. This texture gives the impression of age and weathering, enhancing the tactile realism of the tile.
