Gold necklaces come in various types, including chains, pendants, chokers, and layered necklaces. Chains can vary in thickness and style, such as cable, curb, or figaro. Pendant necklaces feature a charm or decorative piece hanging from the chain. Chokers fit snugly around the neck, often made from gold or mixed materials. Layered necklaces combine multiple chains or strands for a stylish, layered effect. Each type offers a unique look, catering to different fashion preferences and occasions.
