I'd love to see the dress for which Ms Carnegie designed this pin. Maybe linen in yellow, white with light greens. This is a lovely pin, The petals are a light, clean green enamel with a small yellow enamelled tedril at the bottom. White beads & some rhinestones complete the look.
It is about 2 5/8" long. One of the beads is topped with a rhinestone, but the others do not show signs of ever having had stones on them
