Most of the pearls we see in jewelry stores are culture. They actually were grown on a pearl farm. Rivers, lakes or oceans can be served as pearl farms.

Oyster and mollusks need clear, tranquil waters at a temperature of about 20-30 º C (or about 68-86º F)to ensure proper growth. When an oyster or mollusk is between 2 and 2.5 years old, it is time to be implanted with a tiny bead that will grow into a pearl. It will take an oyster or mollusk 2 to 5 years to produce a pearl. The implanting process involves special technology that ensures a high survival rate. Winter is the best season for pearl harvesting, because pearls tend to have a deeper luster at this time of year. Before the pearls are available in the market, they go through a process of sorting, cleaning, bleaching, and polishing.
