Typically produced in marine oysters, these pearls form when an irritant is intentionally placed within the oyster. Japan is renowned for Akoya pearls, while areas like Australia, Tahiti, and French Polynesia are known for South Sea and Tahitian pearls, respectively.

Saltwater pearls, such as the luxurious Tahitian, often boast a more uniform shape and a higher luster. These characteristics, alongside their rarity, contribute to their higher price point.
