Not strictly a pearl matter since it isn’t a pearl producing oyster but we can still note this huge record breaking oyster which is reckoned to be possibly as old as 20 years.
The oyster is a Pacific Oyster (Crassostrea gigas), found in the Wadden Sea, off southeastern Denmark and part of the North Sea.
It is still alive and growing in a sea centre. It is 35cm and 11cm wide. It’s attached to five other oysters, so the total weight is 1.62kg
It will now live out a comfortable and cosseted retirement in the sea life centre in Denmark, fed on plankton and algae.
