PROMPT — Art Deco “Flip-Halo” Ring (Landscape 7:5)  Create an ultra-realistic jewelry render of a never-before-seen Art Deco target ring with a lenticular “flip” halo effect.  Design: - Center stone: square cushion (squircle) vivid blue sapphire, 2.5–4.5 ct, medium crown. - Double concentric halos built from thin louver-like blades:   • Odd blades hold French-cut sapphires, each tilted +15° toward the viewer.     • Even blades hold carré-cut diamonds, each tilted −15° inward.     → From a head-on view the halo reads as a continuous blue band; at ~25–30° the diamonds flare, forming a dotted radial corona (“flip” effect). - Bezel & steps: platinum (or 18K white, nickel-free), stepped geometric bezel (3 tiers) with crisp edges and fine milgrain on the outer rim. - Outer frame: seamless calibré-cut sapphires following a square-cushion outline with strengthened keystone corners. - Gallery (side view): pierced “skyscraper grille” architecture; include a single hidden baguette accent (tsavorite or pink sapphire) as a maker’s mark. - Shoulders/shank: three parallel Deco buttress steps, V-notch detail; comfort-fit underside. - Ring size reference: EU 54 (Ø ≈ 17.2 mm).  Art direction: - Primary hero angle: three-quarter macro at ~30° to reveal the flip effect; include a secondary top-down reflection on the surface to hint the continuous blue state. - Lighting: museum-grade softbox, ~4500–5000K; clean caustics; controlled speculars; polarization to reduce glare; realistic diamond fire/dispersion. - Materials & finish: razor-clean facets, crisp prongs/walls, precise seat geometry; fine milgrain texture visible; no dust/fingerprints. - Background: neutral dark velvet or matte graphite; subtle vignette; luxury editorial style. - Quality: 8k, photorealistic, physically based ray tracing, shallow depth of field with tasteful bokeh.  Negative cues: - No filigree lace, no Edwardian/flowery motifs, no logos/watermarks, no excessive HDR bloom, no cartoonish stylization, no hand/finger model.  Aspect ratio: 7:5 (landscape).
