stone basin 3d model

Ancient monolithic stone boulder carved into a deep circular basin, massive square block, thick heavy mass. Top surface flat but uneven, slightly concave from age, visibly hand-worked, dense chisel scoring radiating around basin rim, smoother from abrasion, compacted granular stone, shallow pits and softened edges. Sides dramatically rougher and more primitive — raw quarry-split faces, jagged fractured planes, deep vertical fissures, sharp mineral protrusions, heavy porosity, flaking sedimentary layers, larger cavities and erosion pockets. Strong contrast between refined top plane and brutal rugged sides. Earthy sandy beige, muted ochre, darker mineral staining in recesses. Deep hollow basin with smooth interior walls and shadowed depth. Hard raking light emphasizing relief and displacement, hyper-detailed photorealism, black void background --ar 1:1 --v 6 --style raw --q 2 heavy worn texture on sides
