Shell pearl - Kai Pearl

Japanese: 貝パール - かいぱーる
Shell pearl - Kai Pearl

...Nowadays, fish scale foil, which has the drawback of discoloration, is no longer used, and instead white lead, titanium dioxide, and even synthetic resin pearl foil are used. Among artificial pearls, those called "shell pearls" or "semi-pearls" are artificial nuclei for cultured pearls that have been coated with pearl foil (about seven times). Those called "imitation pearls" or "majolica pearls" are glass beads or plastic spheres that have been similarly painted (five times or less).

*Some of the terminology that refers to "shell pearl" is listed below.
