Preciosa Nacre Pearls are a superb imitation of natural or cultivated pearls. They 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.
Their lustre and shine makes them hard to distinguish from genuine pearls. They are also highly resistant to abrasion, UV radiation, and to alcohol-based perfumes. The production of CRYSTAL NACRE PEARLS by Preciosa involves environment-friendly methods and work procedures in accordance with EC regulations.
4 mm diameter round beads, sold in 11.5 cm strands containing 31 beads. The black colour pearls are very black and do not have such a noticable pearly lustre, a little like opaque black glass.
