An Art Nouveau adjustable woven gold bracelet in the form of a coiled serpent with a rose-diamond set head and ruby eyes, in 18k. France

Serpent jewelry is a perennial theme. The motif reached a feverish level of popularity after Prince Albert
gave a snake engagement ring to Queen Victoria. The snake in this
case signified eternal love. But snake jewelry dates back to ancient times. For the Egyptians, the creature represented royalty and the divine; for the Greeks, the full circle formed by a serpent eating its tail - the ouroboros, which literally means "tail-devourer" - evoked the circle of life. Snake jewelry continues to make a striking statement, and many pieces feature eyes and
foreheads encrusted with gemstones, as seen in this extraordinary example.
