A LOCKET is a small, usually round or oval-shaped container that is used to hold a tiny portrait or other small item. It is typically made of metal, such as gold or silver, and often has a clasp or hinge that opens to reveal the contents inside. The term 'LOCKET' comes from the French word 'lachette, ' which means 'little box.' Lockets have been popular since the 16th century, when they were used to store locks of hair or other mementos. Today, lockets are often worn as jewelry and can be personalized with a photo or other meaningful image.
