The oyster fishers would go out into the sea on ships, The diver’s equipment was basic, a loin cloth, nose clip of wood and a leather sheath to hold the oysters.
The diver descended with two ropes: one attached to a net for collecting the oysters the second attached to a stone weighing five to seven kilograms to speed up descent. They would free dive and collect oysters.
2000 oyster shells need to be opened before finding a single beautiful pearl.
So on the docs of a small village there would be ships brining crates or nets of oysters into a outdoor working place on the docs, they would empty the oysters and cut them open the ones that didn't have pearls in them they would trade, export, toss away, eat, or sell to other places, the ones with pearls would set on a table where the pearl was carved out and set in a large container of water to clean off, then the pearls would be given to jewlers to make jewelers then would be shipped off for trade.
There was no Oyster farms per say in this area, they would hut them then clean them off in a outdoor working place and then given to jewelers or blacksmiths
the picture is a example, it would be under a roof like with open sides, some nets with oysters in it that are collected and hunted then they are cut open, non pearl oysters go into a separate bucket to be traded, and the pearls are cut away places in water, cleaned, then placed in different buckets and exported
