I love these little pins. This one has the hallmark for 10K gold. The enamel is very fine Colors are pinks, and green. The enamel has a shine to it. In the center of the flower is a small cultured freshwater pearl. The little brooch measures 1" X 3/4". Weight is 2.5 grms. The clasp is an old C clasp that holds fine. With my loupe I see what looks like enamel loss to the green leaves, but it is so uniform that I think the enamel was made like this. Some people call these beauty pins, but I just call them lovely little pieces. Condition is excellent. I would date this cute little brooch at c1900-1910.
