Antique Cloisonné Pin - Sterling

Antique Cloisonné Pin most likely Victorian. Two deep emerald greens on sterling silver. I’ve always worn this as a pendant but the 1.5” closure pin is fully functional & secure. Pin is not perfect but luckily the imperfections are along the edges and do not detract from its elegant beauty. Approximately 1 3/4” x 3/4”. Purchased from an antique store in Melrose, MA in the late ‘70’s ( one owner since then).
