stone basin 3d model

Ancient monolithic stone boulder carved into a deep circular basin, overall trapezoid form — wider at the base, subtly tapering inward toward the top, thick heavy mass, primitive quarry-hewn geometry. Top surface flat and planar but imperfect, slightly concave from age, visibly hand-worked with dense chisel scoring around the basin rim, compacted granular texture, finer pores, shallow pits, smoother from abrasion, softened edges. Sides raw and dramatically rugged — fractured quarry-split faces, deep vertical fissures, stratified sedimentary layers exposed, sharp mineral protrusions, coarse crystalline grain, heavy porosity, flaking crust, erosion pockets and larger cavities. Strong contrast between refined flat top plane and brutal textured sides. Deep hollow basin with smoother carved interior and shadowed depth.
