The History of Human Adornment… since Cavemen
An intriguing and hands-on overview of the origin of humans’ desire to wear jewelry. As beads were the first material object not necessary for survival, they have been considered an indicator of when early hominids developed the ability to symbolize and thus become “modern man”.
