Freshwater Pearls

BY ARTHUR THOMAS


The freshwater pearls that are recovered from various varieties of unio mussels have enjoyed a long history of use in items of personal adornment.

The Romans, under Julius Caesar, invaded the Cassiterides or tin islands (Britain) in 55 BC in search of plunder and slaves. In addition to tin and zinc the islands were an important source of gold, silver, lead, wool and corn.

However the Romans did not discover the river pearls until 43 AD when the Emperor Claudius decided to occupy the islands and incorporate them into the Roman Empire. Continue reading…


Akoya Cultured Pearls

In Japan the pearl farmers begin to lift their harvest in December.  It is winter, the water is and nacre deposition has virtually stopped but they believe this is the time that the lustre of their pearls reaches its peak.

Once the flesh of the parent molluscs has been removed the whole crop is immersed in a saline solution.

Pearl Farms - Marge Dawson

Many interesting and different Pearl Farms are scattered around the World. Pearls from rivers and lakes are called ‘freshwater pearls’ while all others are called ‘sea pearls’.

Hazards Pearl Farmers face, include wild storms at sea resulting in loss of crops, ‘Red Tides’ that use up the water’s oxygen, thieves that steal crops and others that blow up coral reefs for the calcium content.

It takes a minimum of 18 months to 2 years years for strong pearl nacre growth. Pearl divers need to continually clean the undergrowth off the oyster shells, growing in heavy wire baskets underwater, so that oysters can feed and grow their pearls. Continue reading…
