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: refined rectangular-profile plain band with gently rounded corners, about 3.6 mm wide; simple and contemporary, clearly visible but not bulky.
Material and visibility: mirror-polished light champagne yellow gold, midway between white metal and rich yellow gold. Let one clean white-gold highlight travel across the upper edge and a warmer reflection define the lower edge for strong motion readability.
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.
