Hoop Earrings can be fun. Some of these hoops can be opened and the beads exchanged for others. They come in gold-plated and silver-plated; acrylic, glass, crystal, or lampwork glass. The small bead at the top is stationary. The earwires can be pierced or clip-ons. Please include in the notes section on your order form if you need clip-ons. Otherwise, you will received pierced ear wires.
