Design a modern sculptural vase with a beautiful elegant silhouette and a refined decorative presence. Make it about 260 mm tall with a stable rounded base, a gently swelling body, and a graceful neck that narrows before opening into a soft flared rim. Give the overall form smooth continuous curvature and balanced proportions so it feels calm, sophisticated, and luxurious. Add a subtle creative detail by introducing a gentle faceted rhythm or soft vertical contouring around the body, keeping the effect understated and harmonious rather than busy. The vase should feel like a premium contemporary home object with clean surfaces, polished transitions, and a timeless artistic character.
