Create a premium jewelry photograph featuring one gold ring with a small oval green gemstone. Place the ring upright on a gently folded ivory linen surface, with its setting and band clearly visible. Composition: close-up three-quarter view, ring slightly right of center, shallow depth of field, 4:5 vertical format. Lighting: a large soft studio light from the left with controlled reflections on the gold and a subtle highlight inside the gemstone. Style: refined accessories photography with realistic metal texture, precise gemstone facets, and a warm neutral palette. Keep the ring's shape continuous and the gemstone setting structurally plausible. Do not add extra jewelry, floating stones, hands, text, logos, or watermark.
