[Problem] To provide a technology whereby a mantle inserted together with a pearl nucleus forms a pearl sac so as to surround the pearl nucleus and whereby the pearl nucleus encased in the pearl sac can be engrafted inside a mother-of-pearl. If the pearl sac fails to form, the pearl nucleus is ejected from the mother-of-pearl. Pearl productivity can be increased by promoting the early formation of a pearl sac. [Solution] The present invention provides a pearl nucleus characterized by the surface thereof being positively charged. The present invention also provides a pearl nucleus having coated on the surface thereof a substance having a positive charge. The substance having the positive charge is an organic or inorganic compound that has a plurality of functional groups exhibiting positive charge.
[Problem] The properties of artificially produced pearls are determined by the mother-of-pearl and the inserted mantle. In conventional technology, the type of pearls that can be artificially produced have been limited because the mother-of-pearl and the shell from which the mantle is derived were the same type. [Solution] Provided are: a mother-of-pearl holding therein cells derived from a type of shell different from the mother-of-pearl; a production method for said mother-of-pearl; and a production method for pearls using said mother-of-pearl. This mother-of-pearl has reduced nucleus rejection and mortality, even when a piece of mantle from a different type of shell is inserted into the mother-of-pearl. A pearl is formed from the inserted mantle piece, therefore a pearl can be produced that has the properties of the shell from which the mantel was derived.

A column (1) is assembled by packing a first column (10) with an upper layer (14) constituted of sulfuric acid/silica gel and a lower layer (15) underlying the layer (14) and constituted of silver nitrate/silica gel and detachably connecting a second column (20) packed with an alumina layer (23) to a lower end part of the first column (10). An oily liquid containing a polychlorinated biphenyl, such as an electrically insulating oil, is added to the upper layer (14) and this column 10 is kept for a certain time while being heated at 35°C or higher. An aliphatic hydrocarbon solvent such as n-hexane is supplied to the upper layer (14) having been cooled to ordinary temperature. As a result, the polychlorinated biphenyl trapped in the first column (10) is dissolved in this aliphatic hydrocarbon solvent and then flows to the second column (20). This polychlorinated biphenyl is trapped by that part of the alumina layer (23) which is located near the inlet of the second column (20). The second column (20) is then detached from the first column (10). A hydrophobic solvent such as toluene is supplied to and passed through the second column (20) in the direction reverse to the n-hexane passing direction. Thus, an extract comprising a small amount of the hydrophobic solvent and the polychlorinated biphenyl dissolved therein is obtained. The time required for obtaining the polychlorinated-biphenyl extract after addition of the oily liquid to the first column (10) is generally as short as about 2-10 hours.
