It is a popular souvenir in pearl-producing regions such as Ise-Shima, and is also distributed as educational material in schools and jewelry stores. It combines academic value with decorative appeal, capturing the long years it takes for a pearl to form in a single frame. Product Name: Cultured Pearl Growth Specimen (English Name: CULTURED PEARL Specimen Case) Top Section: Shells of Akoya oysters are arranged sequentially, from juvenile to mature, allowing you to observe the process of nacre formation. Middle Section: Several actual extracted pearls are fixed in place. A notable feature is the variety in size and luster. Bottom Section: Many types include mother-of-pearl shells that have opened to the left and right, or rare "twin pearls" that overlap like twins, illustrating how pearls grow inside the oyster. Picture Frame: Typically, the frame is a substantial wooden frame with glass panels, and the back has hardware for wall mounting. Akoya pearls are usually cultivated over a period of one to two years, from nucleus insertion to harvesting. This panel allows viewers to understand the process by which the "radiance of life" is created, making it popular among gem collectors and those interested in science education. 41*32*2cm 954g (I1158)
