Pearl Farming
Production Of Cultured Pearls On Pearl Farm
So what exactly does "cultured" mean? Is it a "real" pearl? Well....are the strawberries you buy at the grocery store "real strawberries"? Yes, "cultured pearls" are "real pearls." Say someone really liked strawberries, but could never find enough of them in the woods, or the ones they found were too small, or too tasteless?That person is glad that some intelligent folks figured out how to propagate strawberries and develop them into large, sweet, red gems that explode with flavor.
Cultured pearls happen much the same way...through planning, development and farming techniques. My son planted strawberry seeds this year in a planter. Without the seeds, no strawberry plants would have sprouted. Without a little help, most mussels or oysters won't grow a pearl either.
But there are ways to "start a pearl" growing in these mollusks (or mollusks). (Mollusks are any of numerous chiefly marine invertebrates of the phylum Mollusk, typically having a soft un-segmented body, a mantle, and a protective calcareous shell and including the edible shellfish and the snails.) Several people worked on figuring out how to start a pearl growing, but Mikimoto is often the man credited with carrying the process to full development.
It's similar to taking a plant cutting. Has your mother ever visited a friend's garden who shared a "slip" of geranium with her so she could start her own plant? Well, in a similar way, to get a cultured pearl started, the mollusk needs a piece of mantle tissue from another mollusk. A tiny piece of mantle tissue from a mussel or oyster is inserted into a live mollusk which is set back into a body of water. A "pearl sac" is developed around the piece and the mollusk began coating the tissue with layers of nacre....the substance of pearls....making a pearl.
Often, for both sea and freshwater pearls, along with the tissue is placed a shell bead which can be a variety of shapes. The mollusk then coats this bead with pearl substance. This way, the shape of pearl can be controlled. Those big, beautiful, round, lustrous pearls that have always been popular are often mostly a shell bead inside with a coating of pearl on the outside. Are they real pearls? Yes! But be sure to buy from a reputable seller to make sure the coating is thick enough not to peel or wear off. An Akoya pearl, by the way, is a pearl from the akoya oyster (Pinctada Fucata Martensii), which lives in salt water. Most freshwater pearls from Asia are nearly solid nacre...you don't need to worry about them peeling.
In Tennessee, however, cultured freshwater pearls are grown around a shell shape making intriguing pearls which are extremely durable and lustrous. Because more pearls can be grown in freshwater mussels than saltwater oysters, the price is often much more affordable. Saltwater, freshwater, natural or cultured pearls...all are amazing gifts from God...and the lowly, humble mollusk. Enjoy those pearls! The mollusks worked hard to make them for you.
