Unlike synthetic glass pearls, SWAROVSKI ELEMENTS's Tahitian-look crystal 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. They are also resistent to perspiration, perfumes, UV rays, scratches and washing and warms to the skin as do real pearls. When wanting to look your best, use only genuine SWAROVSKI ELEMENTS beads!
