"Cameos are often worn as jewelry. Stone cameos of great artistry were made in Greece dating back as far as the 6th century BC. They were very popular in Ancient Rome, and one of the most famous stone cameos from this period is the Gemma Claudia made for the Emperor Claudius.
The technique has since enjoyed periodic revivals, notably in the early Renaissance, and again in the 18th and 19th centuries. The Neoclassical revival began in France with Napoleon's support of the glyptic arts, and even his coronation crown was decorated with cameos.

reign, and his granddaughter, Queen Victoria, was a major proponent of
the cameo trend, to the extent that they would become mass produced by
the second half of the 19th century." READ MORE
