BIRTH OF A PEARL
Ancient Greeks believed, when the sun went down, oysters, attracted by moonlight, would float to the surface, open their shells, and collect the glistening evening dew. The dew would soon be transformed into a radiant pearl.
Many scientists and poets have tried to explain how pearls are formed, but recent observations showed that few if any of natural pearls x-rayed contain the grain of sand or irritant at the origin of the gem,
The latest acknowledged explanation is that pearl formation is triggered by an occurrence resulting in the disruption of the epithelial cells of the mollusks within its soft tissues,
This occurrence can be an accident, an intrusion and/ or a reaction to a parasite. The fact that it takes up to 20,000 oysters to find a decent pearl combined with the button industry appetite for oyster nacre lead to the progressive depletion of natural oyster beds.
