写实三维渲染，正方形画幅，平视正视角居中展示一件做旧银质执壶，壶身带有哑光银灰色金属质感和细微使用磨损痕迹，圆球形壶腹中部装饰一圈錾刻卷草缠枝纹样，纹样上下配有平行细边框；细长弯曲的流口朝向左上方，右侧为带卷涡端点的弧形把手，高颈部带有两道环形凸起装饰，穹顶形壶盖顶端配有桃形摘钮，下方为外撇式圈足；背景为从深炭黑到浅灰的渐变纯色背景，壶底带有柔和暗投影，影棚侧前方柔光照明，金属表面呈现柔和自然高光，整体画面干净无多余杂物。

Photorealistic 3D rendering, square format, front eye-level centered display of an antique pewter-toned silver ewer, with matte silver-gray metallic finish and subtle signs of wear. The bulbous midsection features a band of engraved scrolling foliate patterns framed by parallel thin borders; a slender curved spout angles toward the upper left, while the right side holds an arched scroll-ended handle. The tall neck has two raised ring bands, a domed lid topped with a peach-shaped finial, and a flared circular footed base. Background is a smooth gradient from deep charcoal black to light gray, soft dark shadow beneath the vessel, lit by studio soft light from the front side, creating natural gentle highlights on the metal surface, with no extra clutter in the frame.
