Preciosa® Round Pearls MAXIMA 1H are a superb imitation of natural or cultivated pearls. They have a crystal ballcore which has several coats of nacre applied, using a technology that is very similar to the natural production of pearls. Preciosa® Nacre Pearls have a gloss on them which makes them indistinguishable from genuine pearls. They are also highly resistant to abrasion, UV radiation, and to alcohol-based perfumes. Available in a variety of shapes, sizes and colours. The production of CRYSTAL NACRE PEARLS by Preciosa® involves environment-friendly methods and work procedures that are in accordance with European Community regulations.
