Preciosa Crystal Nacre Pearls are a luxurious compliment to Preciosa cut crystal beads. The brilliantly sparkling facets of crystal beads paired with the sensuous luster of Preciosa pearls result in an enchanting marriage of surface glow and texture. Preciosa pearls have a crystal ball core which has several coats of nacre applied, using a technology that is very similar to the natural production of pearls. Crystal nacre pearls have a gloss on them which makes them indistinguishable from natural pearls. They are also highly resistant to abrasion, UV radiation, and to alcohol based perfumes.
