Definition of South Sea Pearls

A South Sea pearl is a specific kind of pearl that is produced only by the pinctada maxima mollusk. These pearls are produced in both the Indian and Pacific Oceans in the Philippines, Australia, Myanmar and Indonesia.

Geography

The South Sea is between northern Australia and southern China. The South Sea is the natural home of the pinctada maxima mollusk.

Identification

The pinctada maxima mollusk comes in two varieties that are set apart by the different colors of the outer edge of the inside of the shell. This mollusk can only accept a single nucleation at one time, although the mollusk can be successfully nucleated as many as three times during their lifespan.

Size

South Sea pearls grow to be one of the biggest cultured pearls in the entire world. An average sized South Sea pearl is 13 mm. The average size range of South Sea pearls is between 9 mm and 20 mm.

Effects

South Sea pearls become as large as they do for several reasons. One reason is the large size of the pinctada mollusk to begin with. This oyster mollusk can grow to be as large as twelve inches across. Another reason is the length of time that it takes for the pearl to grow within the mollusk. South Sea pearls are left to grow within the mollusk for at least two years. A third factor that contributes to the large pearl size is the environment of the South Sea. The temperature of the water in the South Sea is warm and this warm water temperature increases the metabolism of the mollusk. Additionally, the South Seas are very clean waters that are abundant with plankton. This healthy environment enhances the pearl production within the mollusk.

Features

South Sea pearls have distinctive features. They have a satin-like shine that is unlike any other kind of pearl. This is due to the warm water environment in which they grow. South Sea pearls also have a color range that is uniquely their own. The colors range from white to silver to even a golden hue that is considered quite rare.
