CULTURING OF PEARLS

A method of producing cultured pearls in abalones without endangering their lives, which comprises the steps of: perforating a hole through the shell of the abalone, depositing a nucleus bead on the reproductive organ of the abalone through said hole of the shell, covering the hole with a lid and bonding agent, and raising the thus treated abalone until the nacreous concretion to be gradually formed about the bed grows sufficiently great within the body of the abalone; in order to culture desirably round pearls, the method insures that the bead is firmly held in the prescribed position on said reproductive organ through the period of culturing.
