Pearls are stunning and often made into jewelry. The prices for pearls vary based on the quality, color, size and type of pearl, but harvesting pearls can be a very profitable business. The ideal harvesting is done at a pearl farm, where the pearls are guaranteed due to grafting, but harvesting can be done with wild oysters, muscles or clams as well. Wild pearls are often more valuable because they are often larger and higher in quality than the cultured pearls, which are allowed to form for a specific amount of time, but they are hard to find.
Things You'll Need
- Thin knife or oyster knife
- Pearl oysters, mussels or clams
Wait until the winter months to start harvesting. According to Pearl Guide, winter harvesting is common because the oyster’s metabolism is slowed and the slowed nacre deposits will result in better luster on the pearl.
Pull the pearl oysters, clams or mussels out of the water. A pearl farm will usually require only pulling up a net that contains the animals. For capturing the wild creatures, the process will vary based on the location, size of the animal and supplies available, but the easiest option is to capture it in a net and pull it out of the water.
Slide the knife between the shells and gently pull the oyster, clam or mussel open. Some species of pearl producing animals are killed to extract the pearl while others are not. When dealing with the animals that are killed, the shell can be pulled apart until completely open; otherwise, it should only be opened enough to pull out the pearl.
Put a plug into the clam to keep it open. Like the grafting process, extracting the pearl without killing the oyster requires putting in a plug to hold the shell apart.
Cut the oyster and use tweezers to remove the pearl. Remove the plug and allow the oyster time to recover before grafting with the oyster again. Species that are killed can be pulled open and have the pearl cut free without as much gentle or careful work.
