A Brief History of South Sea Pearls
This saltwater mollusk can reach very large sizes. In the wild, specimens 30 cm across weighing 5 kg are not unheard of. Because of their large size, they can accept large bead nuclei and produce very large pearls, from 8 to 20 mm.
The northwest coast of Australia produces most of the world’s white South Sea pearls, while production in the Philippines focuses on the golden variety. Indonesia also produces large numbers of South Sea pearls in both colors. The white-lipped Pinctada maxima produces white pearls, while the gold-lipped variety produces golden pearls.
Although cultured blister pearl operations in Australia began as early as 1906, they didn’t successfully cultivate whole pearls until after World War II. In fact, the Australian government passed a law in 1912 prohibiting any cultured pearl operations in an effort to prevent competition for the natural pearl industry.?Nevertheless, once the cultured pearl industry boomed in Japan, it was clear that was the way forward.
