Most South Sea cultured pearls are grown in Australia, the Philippines or which other country?
Correct Answer:
Indonesia
Explanation:
South Sea cultured pearls come from warm tropical seas where the large Pinctada maxima oysters thrive, allowing the production of the biggest cultured pearls. The primary producing regions are Australia, the Philippines, and Indonesia. Indonesia completes the trio because its extensive warm coastal waters host many Pinctada maxima farms, yielding the large, lustrous pearls that define the South Sea category. Other options fit different pearl types: Japan is famous for Akoya pearls from a smaller oyster, while India and Vietnam are not major suppliers of South Sea pearls.
