Rich brown studs in a moonglow finish. Each post earring measures approximately 1/2" or 12mm in diameter. See the last pic of a model wearing these earrings in the steel grey, to get an idea of the size & scale when worn.
Most all earrings are made with vintage lucite parts that were made in the US in the 1960's - early 80's. We hand-set them with surgical steel earring posts and they have sturdy surgical steel/acrylic backings on them as well. Light-weight & fun to wear.
