Many simulated pearls offer some drawbacks. Contact with perfume or perspiration can cause plastic imitation pearls to lose their pearl coating. Because faux pearls are easily scratched, cleaning them can be challenging. Crystal pearls, on the other hand, are washable and are not susceptible to damage from perfume or perspiration. They are also resistant to scratches.
And as is the case with genuine, cultured pearls, the temperature of Crystal pearls changes to reflect the temperature of the wearer's skin. Because this quality is one reason jewelry lovers cherish genuine pearls, the realistic color, luster and feel of Crystal pearls are major selling points.
