The invention discloses a method for cultivating a round pearl of a penguin pearl shell. The method uses the penguin pearl shell with height of about 10 cm as a pearl cultivating shell, the penguin pearl shell with shell height of about 6-7 cm or martensite as a small slice shell. The planted pearl core shall be small in diameter, and the core inserting part is a left bag core position of the pearl cultivating shell. The pearl cultivating shell uses the penguin shell with growth age for about one year and a half and the shell height of about 10 cm, and the penguin shell is quick in growth rate and big in core position; after the core plugging treatment, the death rate is low and the core remaining rate is high. The small slice shell uses the 6-7 cm small shell, and this specification of shell has thin outer sleeve film, and the produced small slice can be more tightly combined with the pearl core. Before plugging the core, byssus is sheared off by an oblique caliber, so as to reduce the influence on view and cutting opening in the course of plugging the core. Besides, by adopting the small bead core, the method avoids contacting and contaminating livers of the pearl cultivating shell in the course of planting the core, and improves the core remaining rate and the pearl quality.
