Lockets are usually worn on chains around the neck and carry small personal items, photos, or memories of a loved one.
They are the reason a small clipping or tress of hair is called a “lock of hair.”
The word locket probably arrived in England in 1066 with the invasion of William the Conqueror (circa 1028-1087), who would have used the Old French word loquet to describe a small lock or latch.
The small ornamental case with a hinged cover and latch, as we know it today, surfaced in 1679.
