14K Yellow Gold with Blue and Yellow Cloisonne Enamel Butterfly Stick best Pin, Marked

Beautiful gleaming 14K yellow gold stick pin with a beautifully enameled cloisonné butterfly in blue and clear yellow. 1910s or 20s, at best guess, although it's hard to tell with quality enamel pieces, since they are so timeless. Good vintage condition, about 2" long. Base is NOT gold. SJB8
