History and Cultivation

Natural South Sea pearls were found in the sandy shallow waters inside of large oysters harvested for their shells as well as for food. These pearls were found only in a handful of the harvested oysters. As these oysters became depleted in shallower waters, diving techniques were invented and used to delve into deeper waters. In the 1950s the first Australian pearl farm was established to culture these large pearls.

However, since they come from different regions of the world and a different host oyster, we separate the two. Of the two colors, golden South Sea pearls are more prized.
