We wear history. The ornate, symbolic jewelry worn by ancient Egyptians inspired revivals over the last few centuries. In the late 1700s, Napolean's war in Africa sparked a widespread interest in Egypt among Europeans. These were reflected in popular jewelry designs of the time. This popularity "boomed again during the 1920s, after the discovery of Tutankhamun’s tomb in 1922 spread Egyptian imagery throughout the western world", according to Collectors' Weekly.
Fashion is always a response.
