ornate stone staircase 3d model

**“Create a highly detailed 3D model of a grand double staircase inspired by classical palace architecture. The staircase is made of polished dark marble with subtle gold veining. It begins with a large semi-circular base platform, from which broad stone steps rise symmetrically to a central landing. Both sides of the staircase curve outward gracefully, supported by ornate balustrades. The railings feature antique carved balusters, gold-accented detailing, and decorative post capitals topped with spherical white lamps. The overall design should feel regal, elegant, and monumental, with smooth stone surfaces, accurate step proportions, and detailed ornamental carving on posts and railings. White or transparent background for export. Perfect for cinematic interior environments or game-ready palace assets.”**
