Old Silver Hoop Earring from Morocco

This single Moroccan earring is from the 19th century or early twentieth century.  The earring features a raised circular central section that has dark blue, green, and red glass insets. This is flanked by smaller elements, each with a glass inset.  The earring tests as high-grade silver.
