thick gold rope chain 3d model

Create a wearable thick gold rope chain necklace for a character. The necklace must look like a real luxury rope chain, with clearly visible twisted interwoven links. Make it very thick and heavy-looking, similar to a premium 18k gold chain. The chain should have strong volume, rounded form, deep braided detail, and realistic jewelry proportions. It must be a proper necklace for wearing on a human character, sized naturally around the neck. Keep the chain clean, symmetrical, and fully connected. Do not make it look like a simple rope, tube, or solid block. Do not flatten the shape. Do not turn it into a fuzzy mass. Use a realistic polished gold material. Isolated object only, clean studio presentation, focused on the necklace geometry.
