South Sea Pearls Characteristics

The main characteristic that differentiates South Sea pearls is the nacre, which is thicker than other types of pearls (2-4mm). The nacre is the natural coating with which the pearl covers the nucleus. Another characteristic is the size, that while in Akoya pearls goes from 3-9mm, in South Sea pearls it goes from 8-20mm, in some exceptional cases with 22mm pearls. It also highlights the luster, which has a satin luster compared to akoya or freshwater pearls.
