Rangiroa has a pearl farm. Pearl oysters are usually farmed far out in atolls without tourists, but this one is on Rangiroa.The workers chuck oysters that are grown right outside their door in the lagoon.
Oyster shells are shipped to India where they are made into buttons.
These workers attach oysters that are impregnated with a pearl seed to strings that are hung in the lagoon.
Although edible, there are too many oysters to be eaten.
Oyster nets will be filled with shells and hung in the lagoon. Not many of them will produce high quality pearls, but all of them wind up as fashion jewelery or buttons.
