jewelry ring 3d model

Create a production-ready 3D jewelry ring matching the reference exactly. Preserve the rectangular architectural face, raised 3D deer, antlers, floral scrollwork, side circular ornaments, layered borders and top stone setting. Do not simplify or redesign details. Ring: Japanese size 25, inner diameter exactly 21.0 mm, inner circumference ~66 mm. Shank thickness 3.0 mm, side width 4.0 mm. Top face ~25 × 18 mm. Center stone: exactly 6.0 × 4.5 mm, oriented 6.0 mm wide × 4.5 mm long. Create a real recessed seat and solid ~0.8 mm diameter prongs. All ornaments must be real 3D geometry, not textures. Deer relief 1.2–1.5 mm high; ornamental relief 0.8–1.2 mm. Minimum structural thickness 0.8 mm. Maintain perfect symmetry, solid connected geometry, no floating parts, no zero-thickness surfaces, no self-intersections, and watertight manifold topology. Preserve maximum fine detail. Final model must be suitable for jewelry casting/3D printing.
