Alex and Ani Sugar Skull or Calaveras earrings. These retired earrings are a very unique and cute piece. Made from their trademark Rafaelian Gold. Perfect for Day of the Dead or Dios de Los Muertos, they would also work for a subtle Halloween vibe. You can definitely wear them daily as they are so sweetly understated. No visible flaws as they were tucked away in my jewelry box for about a decade. Calaveras are a representation of a human skull or skeleton and are a symbol of mortality and death. They are also a popular offering during the Day of the Dead because they represent the sweetness of life. Calaveras are used in the Mexican celebration of the Day of the Dead and All Souls' Day.
