diamond crystal 3d model

Create a highly detailed photorealistic 3D model of a natural rough diamond crystal with an irregular, asymmetrical shape and naturally fractured surfaces. The crystal should be colorless to slightly milky transparent, featuring sharp edges, chipped corners, cleavage planes, and realistic geological formations. Include visible internal inclusions, micro-fractures, cloudy mineral deposits, trapped particles, and needle-like crystal structures. Surface details should show rough fracture patterns, subtle weathering, micro-scratches, and natural imperfections. Use physically accurate diamond properties with high refraction, light dispersion, internal caustics, and optical depth. The model should be production-ready with clean topology, UV mapping, and PBR textures. Render in a photorealistic studio environment with HDR lighting, ray-traced reflections, realistic transparency, and scientific mineral specimen quality.
