True micro mosaic from long ago! this 1 inch in diameter has very tiny tiles in many colors with flowers, leaves and more geometric borders. It is not stamped Italy but there is some sort of little mark under the pin stem. Stem is C clasp that works well. Excellent early vintage condition. If you would like to view a newer pin to see something that is NOT micro mosaic, 2569.
