The invention discloses a method for culturing nucleated pearls, which comprises the following steps of: taking a non-nucleated pearl as a nucleus or grinding shells to form the nucleus; cushioning a cell sheet under the nucleus, and implanting at the position of the viscera or foot of a freshwater mussel or nacre; returning the freshwater mussel or nacre to water for culture; and opening the freshwater mussel or nacre to harvest the pearls formed around the nucleus. Because the foot of the freshwater mussel or nacre is positioned above the visceral sac thereof, has a larger space and secretes more nacrum than the visceral sac or a mantle tissue, the implanted nucleus is difficult to be spit out, the self diameter of the nucleus is increased, and the freshwater mussel or nacre secretes more nacrum after the nucleus is coated. The pearls have the advantages of large particles, good transparency and gloss, short growth period and high economic value.

The invention discloses a pearl cultivating method for nuclear pearl, a tool adopting the method and cultivated pearl. The pearl cultivating method for nuclear pearl comprises the following steps: nuclear-free pearl is used as a pearl nucleus or a shell is grinded to form the pearl nucleus; the pearl nucleus is arranged on a cell sheet and then the pearl nucleus with the cell sheet is implanted on viscera or pelecypodium of a mussel or a pearl shell with a tool; the mussel and the pearl shell is restored in water for culture; the mussel or the pearl shell are opened and a pearl formed around the pearl nucleus is harvested. As the pelecypodium of the mussel or the pearl shell is above a visceral sac and has large space compared with the visceral sac or a mantle, and the pelecypodium secretes more nacre, the pearl nucleus cannot be spit out easily if the pearl nucleus is implanted on the pelecypodium and the diameter of the pearl nucleus is expanded, moreover, the mussel or the pearl shell secretes more nacre after the pearl nucleus is coated. The pearl cultivating method ensures that the pearl nucleus can be inserted into the pelecypodium accurately, the cell sheet can wrap the pearl nucleus better and the pearl nucleus has no need of punching a hole. The pearl has large particle, good translucent luster, short growth cycle and high economic value.
