Gold necklaces can break, depending on their particular construction and the care given to them. Gold is a malleable metal that can be bent or stretched if it receives excessive pressure. This means that if a necklace is dropped or handled roughly, it may easily become damaged. Poorly made gold necklaces may also be more prone to breakage due to weak links or clasps in the chain.
Another factor that could contribute to a gold necklace breaking is wear-and-tear from overuse. The chain may become brittle and eventually snap from stretching or other damage if regularly worn.
Taking good care of a gold necklace by avoiding contact with harsh chemicals, not pulling on the chain too hard when taking it off or putting it on, and storing it properly when not in use can help ensure its longevity and keep it looking beautiful for years to come.
