Premium 3D-rendered Image Showcasing an Intricate Geometric Sculpture

Create a premium 3D-rendered image showcasing an intricate geometric sculpture that consists of eight metallic triangular prisms seamlessly connected into a balanced starburst arrangement. Each prism features a highly polished, mirror-like surface that reflects delicate shades of silver and gold. The semi-reflective finish gives rise to dynamic interplay of light where the edges and planes converge. Set against a smooth, dark charcoal gray background with subtle radial lighting, the overall aesthetic is modern, sleek, and refined. No text is included.
