Create a highly accurate 3D jewelry design based on the supplied reference image. Reproduce the ring’s overall architecture, proportions, stone placement, flowing metalwork, and botanical aesthetic as closely as possible. The ring is an elegant white-gold botanical/Art Nouveau–inspired cocktail ring built around a vertically oriented oval black lightning ridge opal cabochon center stone. The center stone is held by four substantial sculptural claw prongs positioned approximately at the upper-left, upper-right, lower-right, and lower-left quadrants. The claws should emerge organically from the surrounding metalwork rather than appearing as separate straight prongs. Surround the center stone with a thin polished oval support/gallery following the stone’s outline. From this central structure, create asymmetrical flowing vines and branches that sweep outward across the shoulders of the ring. The vines should form graceful S-curves and loops, creating an open, airy framework rather than a solid halo. Incorporate leaf-shaped elements into the vines. Each leaf should have a pointed marquise-shaped outline, polished raised border, recessed interior, and a small round accent-stone setting centered within it. Leaves should appear to grow naturally from the curved branches. Add alternating round ruby and diamond accent settings throughout the vine structure. Use several different accent-stone sizes rather than making every stone identical. Larger rubies should act as visual anchors, with smaller rubies and diamonds filling transitional spaces. All round stones should use delicate individual prong settings integrated into the vines. Preserve the reference image’s intentionally asymmetrical composition: the right side rises higher and contains a more elaborate cluster of leaves, rubies, and diamonds, while the left side remains slightly lower and more restrained. Despite the asymmetry, the finished design should feel visually balanced around the center stone. The shoulders should transition into split, intertwined vine-like rails, eventually merging smoothly into a conventional polished rounded band toward the bottom of the shank. Maintain open negative spaces between the vines so the ring remains delicate rather than becoming a solid mass of metal. Important construction details: all decorative vines must physically connect to the main gallery or shoulders; every gemstone setting must have adequate metal beneath it; no floating components; no unsupported prongs; no impossibly thin wires; no intersecting geometry. Prongs should have sufficient thickness for casting and final stone setting. The center basket should provide continuous structural support beneath the cabochon while allowing an open underside. Finish: highly polished white gold, smooth organic transitions, rounded edges, fine-jewelry proportions, realistic castable construction. Avoid bulky CAD geometry, oversized prongs, generic halo-ring architecture, perfect bilateral symmetry, or disconnected decorative elements. Priority: match the reference ring’s silhouette and layout before introducing any creative interpretation. Treat the supplied image as the primary design reference. The finished model should immediately be recognizable as the same ring when viewed from the same three-quarter angle. Required dimensions: US ring size 7. Center setting designed specifically for a 6.0 × 7.2 mm oval cabochon. Model the center stone only as a removable reference volume; final manufacturing model should contain an empty seat for the cabochon. All accent gemstones should likewise be represented as setting blanks/seats rather than permanent stones. Preserve the apparent proportions of the reference design while scaling the surrounding ornamentation appropriately around the 6.0 × 7.2 mm center. Design for lost-wax investment casting and subsequent hand stone setting. Use practical minimum wall thicknesses, structurally supported galleries, properly connected prongs, accessible stone seats, and sufficient finishing allowance. Produce a watertight/manifold solid suitable for STL export, with no floating shells, non-manifold edges, self-intersections, or decorative geometry that cannot be cast or finished.
