Pearl coated on a plastic base. These faux pearl beads are sold loose, but are ready to be strung in your jewelry, craft and clothing designs. Our plastic pearl cabochons are a good quality and value when compared to our line of glass based pearls, but always keep in mind that imitation pearl coatings are a surface coating that can be affected by certain cosmetics or chemicals. As with most imitation pearl items, colors may vary slightly from lot to lot.
