The Seashell Pearl Collection features onyx, mother of pearl and the finest seashell pearls. The inner nucleus of a Belle Étoile seashell pearl is created from carefully carved and polished shells of giant fossilized deep sea oysters. This gives the seashell pearls their consistent weight and causes them to often be mistaken for Tahitian or South Sea pearls. The final product is a strong and lustrous pearl which, with the proper care, can last a lifetime.
