Unlike synthetic glass pearls, SWAROVSKI ELEMENTS's crystal faux pearls have a leaded crystal core that makes them heavier, and SWAROVSKI ELEMENTS's pearl coating is similar to a natural pearl lustre and is consistent in color. It is also resistant to perspiration, UV rays, perfumes, scratches and washing and warms to the skin like real pearls do. This brilliant and bold color complements a wide range of the existing crystal colors, opening up new and innovative combination possibilities.
