background and environment A dark, studio-controlled environment with a smooth black-to-deep-charcoal gradient background. The ring rests on a perfectly polished, glossy black surface that produces a clean, sharp mirror reflection directly beneath it. The background fades softly into darkness with no texture, props, particles, or visual distractions, creating a refined luxury atmosphere. camera and framing A tight macro-to-medium close-up captured from a low, surface-level front-facing angle. The camera is aligned parallel to the surface plane. The composition is centered and balanced for a square 1:1 layout in true 4K resolution. Perspective is natural and optically correct, with no distortion, tilt, or top-down angle. subject and pose or placement The exact same ring as the reference image, preserved with identical design, proportions, stone sizes, prong shapes, pavĂ© layout, engravings, materials, and surface finish. The ring is always lying flat on its side on the reflective surface, forming a clear horizontal oval. The band rests fully on the surface along its lower curve. The main gemstone faces upward toward the camera while the ring body remains completely grounded and horizontal. This lying, horizontal position is absolute and enforced regardless of the reference image orientation. The ring is never upright, standing, tilted vertically, floating, leaning, or partially lifted. product behavior and physical interaction The ring makes full, realistic contact with the glossy surface along the lower curve of the band. A soft, precise contact shadow anchors it to the surface. Beneath the ring, a clean mirror reflection is visible, accurately matching the ringâs exact silhouette, gemstone, prongs, and pavĂ© details, with subtle falloff and slight blur consistent with polished black glass. Gravity is clearly respected with no suspension or instability. lighting and materials Controlled studio lighting with a primary soft key light from the front-left at surface level, producing crisp highlights along polished metal edges and controlled sparkle within the gemstone. A subtle fill light from the opposite side preserves detail without flattening contrast. Metal reflections are smooth and mirror-like with clean gradients. Gemstone refraction is sharp, physically accurate, and consistent with the real cut, with no exaggerated glow, bloom, or altered facets. final constraints The product must remain completely unchanged from the reference image in every aspect of design and construction. No redesign, reinterpretation, or camera angle that causes the ring to appear standing or elevated. The ring must always appear lying flat and horizontally on the reflective surface. No text, hands, props, dust, fog, or decorative elements. Ultra-clean, premium studio quality, high contrast, true 4K resolution, square 1:1 format, with a clean mirror reflection beneath the product.
