Title: High-Resolution, Precision-Engraved Art Deco Cushion Cocktail Ring with Radiating Sapphire and Diamond Mosaic Cluster, Under-Gallery Filigree, and Technical Dimension Call-Outs.This is a high-poly, intricately detailed 3D model of a spectacular high-jewelry cocktail ring, meticulously designed with a geometric Art Deco sensibility and a complex, radiant mosaic cluster setting. The design balances the luxurious brilliance of the primary render (Image 0) with the precise, technical specifications shown in the CAD/dimensional images (Images 1-3). The model is ready for high-resolution studio rendering, virtual try-ons, and high-fidelity product visualization.Visual Aesthetic and Design:Style: Cushion-shaped, intricate cluster cocktail ring with a powerful radial symmetry, characteristic of late Art Deco and high-jewelry design.The Crown: The central element is a large, cushion-cut natural blue sapphire with a complex, multi-faceted step-cut bezel.The Radial Mosaic: From the central sapphire, a mesmerizing mosaic of gems radiates outwards. These include:Alternating radiating channels of custom step-cut (baguette or multi-square step-cut) deep blue sapphires.Radiating channels of round pavé-set diamonds in groups of four (creating a clover-like pattern), bordered by delicate milgrain (beaded) edging.This pattern is repeated to create a perfectly symmetrical, almost architectural pattern on a complex cushion-shaped frame.The Milgrain Work: The entire cushion perimeter and the radiating borders between gem sections are finished with ultra-precise milgrain beadwork. This is visible as the intricate beaded texture in the primary render and explicitly defined on the green plate of the technical drawings.The Filigree Under-Gallery: Beneath the massive crown, a sophisticated filigree gallery of scrollwork, geometric cutouts, and floral-scroll motifs is rendered in blackened or oxidized metal (as seen in the technical drawings' dark under-carriage and the blackened metal of the under-gallery in Image 0). This provides structural support and aesthetic contrast, visible through the side.The Shank: A sleek, high-polish metal shank features a hidden channel of pavé-set small round diamonds running along its side. Plan View:Width: 22.29 mmLength: 22.29 mmTotal Height (from bottom of shank to top of center stone):Side Profile ViewHeight: 9.06 mmShank (Bottom Profile):Shank Width (cross-section): 2.20 mmShank Thickness (bottom profile): 1.50 mmGems and Settings:Center Stone: Cushion-cut sapphire. Bezel facets with complex modified steps.Accent Gems (Crown): Stepped baguette sapphires and round brilliant diamonds (pavé).Shank Accents: Round brilliant diamonds (pavé).Setting Styles: Milgrain beaded bezels and pavé settings with individual micro-prongs.Metal Finishes: Two-tone or blackened-oxidized effect on the filigree and shank vs. bright polish on the primary top cluster (technically a dual-color CAD model).3D Model Specifications:Geometry: High-poly, cleanly topology-optimized (quads), with a focus on geometric precision to replicate the complex milgrain and filigree. Ready for subdivision.UVs: Fully unwrapped and non-overlapping.Texturing:Includes PBR metal maps for multiple finishes: polished platinum, polished yellow gold, and blackened/oxidized metal (to replicate the under-gallery).Custom stone textures for the specific cushion sapphire and radiating mosaic.Render Readiness: The primary render is a representation of the finished high-end studio render.
