These dancing, dangling earrings are based off of this 1826 portrait of Eugenie de Beauharnais by Karl Joseph Stieler shown in the 2nd image.
These are long earrings measuring at nearly 3" in total. They are made with vintage acryllic Pearl beads.
They are shown here with historically accurate hoop findings but are also available as classic leverbacks or hinged leverbacks for non-pierced ears.
