Download scientific diagram | The cultured pearl samples investigated in this study. The pearls from group A were formed as a 1st generation product with an organic gelatinous nucleus. These cultured pearls are not introduced into the pearl trade but are only created to produce an inflated pearl sac. The upper two pearls are from Pinctada margaritifera (Micronesia), the lower two from Pinctada fucata (Japan). The cultured pearls of group B are the 2nd generation product and all come from French Polynesian Pinctada margaritifera production. The 2nd generation pearls contain a baroque shaped bead made from a freshwater shell. © M.S. Krzemnicki from publication: New developments in cultured pearl production: use of organic and baroque shell nuclei | Cultured pearls can be produced both with and without a nucleus. Marine pearl oysters that produce Akoya, South Sea and Tahitian cultured pearls typically use nuclei for their pearl products. The nucleus material used for these beaded cultured pearls is traditionally from | Pearl, Shell and Nucleus | ResearchGate, the professional network for scientists.
