South sea pearls

Characteristics of South Seas pearls

Origin and cultivation

South Sea pearls are cultivated in Pinctada maxima pearlfish, which are the largest of all pearlfish species. There are two main varieties: golden pearlworms (producing gold and yellow pearls) and silver pearlworms (producing white and silver pearls). These molluscs are found in the warm, clear waters of the South Pacific and can take two to three years to cultivate, which contributes to their size and quality as well as their price.

Size

South Sea pearls are generally larger than other pearl species, with an average size between 10 mm and 15 mm, but can reach over 20 mm. Size is one of the factors that contributes to their high value.

Colour

These pearls feature a wide range of natural colors, including white, cream, gold, silver, pink and other shades. Gold pearls are particularly prized and can range in colour from pale yellow to deep gold. The white version can have different undertones.

Shape and lustre

South Sea pearls can come in a variety of shapes, including round, oval, drop-shaped, baroque (irregular) and circular. Perfectly round pearls are rare and very valuable. These pearls have a soft, satiny luster that is often less sharp than Akoya pearls, but deeper and more layered. This luster is due to the thick layer of nacre that forms over a long cultivation period.

Quality and price

The quality of South Sea pearls is assessed by several factors such as lustre, surface clarity, shape, size and colour. South Sea pearls are generally among the most expensive pearls on the market.

Uses

Due to their size, colour and beauty, South Sea pearls are popular in the jewellery industry. They are mainly used to make luxury necklaces, rings, earrings and bracelets. They are often considered a symbol of elegance and prestige.
