This is a single Kebeyle irregular coral nugget and green, blue and yellow enamel on low or no silver. The enamel is intact around the middle, but the 2 and three petals have lost their enamel. There is a curved rod for a pierced ear. I never had a pair. The earring is 7/8" not counting the hook and 9/16" wide and 7/8" deep. I lived in Algeria for 4 years in the 1970s and there was little enamel Kebeyle jewelry. This is from the first half of the 20th century.
