After the pearls are harvested from their oyster home, they are brought back to the main area for cleaning and grading. 

Pearls are sorted into groups of like details and washed together. First, they are placed into  rotating barrels filled with just water and salt. The barrels spin for an hour or two and then the pearls are rinsed with fresh water. 

The next step is to separate the pearls into shapes. The shapes can be drop, circle, baroque, near round, and finally, perfect round. After this, the pearls are graded roughly into High or Low grade. Now, the pearls put into different sizes.
