An empty oyster is an oyster which has been opened and does not contain a pearl.
It can be caught with a big fishing net at the Fishing site just east-south-east of Catherby or it is a common drop from a Rock Crab which are found in Rellekka. They were once tradeable on the Grand Exchange, but were taken off the Grand Exchange in a hidden update.
