ancient stone basin 3d model

**Midjourney Prompt (under 1000 characters):** Ancient monolithic stone boulder carved into a deep circular basin, massive square block with irregular proportions, thick heavy mass, blunt worn corners, primitive quarry-hewn form. Exterior extremely rugged and tactile — coarse sandstone texture, heavily pitted and porous, granular mineral structure, micro-fractures, branching hairline cracks, deep crevices, erosion marks, chisel striations, flaked sedimentary layers, fractured edges. Surface shifts from jagged crust to slightly water-worn smoother patches. Earthy tones of warm sandy beige, muted ochre, dusty taupe, pale gray, darker mineral staining in recesses. Deep hollow interior with thick tapering walls, smoother carved surface, faint concentric tool marks, dramatic shadow gradient emphasizing depth. Strong raking light highlighting texture relief, hyper-detailed photorealism, black void background, 8k --ar 1:1 --v 6 --style raw --q 2
