Fine cultured pearls with thick nacre layers will last for generations if cared for properly. Cultured pearls should be kept free of perfumes, cosmetics, perspiration and dirt. You may gently wipe cultured pearls with a slightly damp cloth. Over time, the silk will stretch, weaken and become soiled. If you wear your cultured pearls regularly, we encourage you to have your cultured pearls cleaned and restrung annually.
