The average size of Tahitian cultured pearls is about how many millimeters?

Explanation:
Tahitian cultured pearls are typically larger than many other cultured pearl types because they come from the bigger black-lipped oyster, and their growth conditions often produce pearls in the 8–10+ mm range. In practice, the average size is about 9 millimeters, with many pearls around 9 mm and some larger, but 11 mm is less common on average. That’s why 9 millimeters is the best match for the average size. Smaller options like 5 mm or 7 mm are below the typical average, while 11 mm is toward the high end rather than the average.
