Pearl harvesting
Pearl farms are establishments wherein mollusks are maintained to produce natural pearls.
It takes 8 months to 6 years to develop saltwater pearls before harvesting while it takes 2 to 6 years for freshwater pearls.
Winter is usually the time when pearls are harvested from pearl farms. This is due to the fact that during winter, the mollusk produces less nacre. Once harvested, the pearls are cleaned and polished and sent on to become fine pearl jewelry.
