Tiny diatoms inspire the pattern; bright enamel does the rest. Daria Salus layers powdered glass over copper and kiln-fires these long drop earrings by hand in the Bay Area. The disc measures about 5/8 inch, with an overall length of about 1 7/8 inches. The longer silhouette gives the intricate diatom pattern a little extra drama. In Enamel Diatom Long Drop Earrings, Daria Salus lets the shape, color, and materials carry the design.
