These earrings are made with an etched bead from the Czech Republic. The ferns are etched onto a rectangle, pressed glass bead, and are about 1.5". I have the fern on black glass, with the color of the leaf varying from grey to a more purple color. This earring is one of my best sellers. The ear wires are gold plate on a surgical steel, nickel free. All Earrings come carded.
