To wear this 14k yellow gold heart pendant necklace, simply open the lobster lock and attach it around your neck. You can wear it on its own for a minimalist look or layer it with other necklaces for a more stylish appearance. When not in use, store it in a jewelry box or a soft pouch to prevent scratches. Clean it gently with a soft, dry cloth to keep its shine. Avoid contact with harsh chemicals, like perfumes and cleaning agents, as they may damage the gold.
