Use case: precise-object-edit
Input image: a localized crop from the original photograph. The transparent mask marks the base of the index finger, the uppermost long finger touching the cheek.
Primary request: add one new simple ring only inside the masked area, unmistakably wrapped around the index finger. Keep the original ring on the ring finger, so two rings remain visible.
Ring design: understated single ridge or very soft knife-edge plain band, about 3.7 mm wide; a simple silhouette, moderate and refined rather than ornate.
Material and visibility: luminous polished champagne yellow gold, clearly warmer than silver and paler than saturated gold. The soft ridge should catch one distinct natural window-light highlight that stays visually legible in motion, without glowing.
Constraints: change only the masked index-finger ring area. Preserve the exact hand anatomy, finger pose, skin, existing ring, face, ear, hair, clothing, lighting, crop, camera, and every other pixel-level detail. No gemstones, engraving, extra jewelry, text, watermark, finger deformation, or beauty retouching.
