The World is your Oyster
Pearls are formed in molluscs, living in both saltwater and freshwater. They occur when the mollusc is invaded by a foreign substance such as a small piece of grit washed in by the sea. At this point the mollusc will immediately start to build natural defences to protect its nucleus by way of adding layers of nacre, creating a pearl as we know it.
Natural pearls are now extremely rare and cultured pearls have become a popular alternative.
There are two distinct categories of cultured pearls:
These pearls are formed when a bead from a freshwater mollusc shell is implanted in the reproductive organ of a saltwater mollusc (oyster) along with a piece of mantle tissue. These pearls are called ‘saltwater beaded cultured pearls’.
These pearls are formed when freshwater mussels are implanted, usually with a piece of mantle tissue, in the mantle tissue area of the mussel instead of the reproductive organ. These pearls are called ‘non-beaded cultured pearls’.

There are five main ways in which a pearl can be treated and each has its own tell-tale signs that a gemmologist will look for when assessing a pearl.
