Cultured 3/4 Blister Pearls

More information is now available on the cultured 3/4 blister pearls that were recently introduced into the marketplace. Cultivated with both salt water and fresh-water nuclei, the material is attractive and durable. This article describes the method of culturing these "pearls" as well as the differences between this material and 3/4 South Sea cultured pearls or assembled cultured blister pearls (Mabe pearls).
