Use the supplied reference image as the sole locked product input. Preserve the product's exact appearance, structure, materials, colors, proportions, logo, label, accessories, and product-set relationship.
Create a 3:4 photorealistic commercial product poster. Lay the single rose-gold teardrop pendant and chain across a pale blue reflective water surface. Add concentric ripples, bright sky reflections, a sun flare, and clear diamond sparkle.
Use a polished premium advertising finish with crisp product focus, coherent perspective, realistic materials, controlled depth of field, and physically plausible lighting. Keep all decorative elements physically plausible and subordinate to the product. Keep existing product text legible when present. No poster text, watermark, extra product, unrelated logo, distorted object, changed product appearance, or unnecessary person.
