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: smooth flat band with softly beveled edges, about 3.8 mm wide; visually clear but refined, not oversized.
Material and visibility: highly polished light yellow gold with a restrained champagne tint, between silver and classic yellow gold. Use a broad clean window-light reflection and a bright rim highlight so the band reads clearly in motion and at smaller video scale, without artificial glow.
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.
