Create a detailed 3D model of a traditional Indian gold necklace with a large ornate pendant, intricate filigree, floral motifs, and geometric patterns. Highlight it with rubies, emeralds, sapphires, and pearls. The chain features interlocking links and small charms. Add Meenakari enamel work in red, green, and blue with motifs like peacocks and lotuses. Ensure it looks handcrafted and opulent.
