How are pearls cultivated?

Answer 1

Answers

Mollusks from the family Bivalvia produce pearls. Oysters, from the family Osteridae, do not produce pearls; a common misconception.

Answer 2

Natural pearls occur in the wild - but they are very rare to find. Thus, pearls are farmed or cultured using pearl oysters. However, fresh water pearls are cultivated from fresh water mussels from the Uniondae family.

Answer 3

There are different sea creatures that are used in order to cultivate pearls. A pearl basically refers to a hard object which is produced inside the soft tissue or mantle of a shelled molusk. Contrary to what you may believe, pearls are not necessarily shiny or perfectly circular (although this is the ideal one.) A pearl is created through calcium carbonate deposits which are done in layers.

Fresh water pearls are cultivated from fresh water mussels from the Uniondae family. These creatures are found usually in fresh waters like lakes, ponds and rivers. They are bivalve mollusks. Most cultured fresh water pearls are baroque in form, which may give it a weird oblong or tear drop shape.

Marine bivalve mollusks are used to cultivate saltwater pearls. Oysters are aslo used. But basically, under the right conditions - any kind of shelled mollusk can create a pearl - by that, meaning a calcified deposit. These pearls though, are not usually iridescent and lack luster. These are basically valueless pearls that vary in look and size, some are circular and look like marbles. Some on the other hand look like heaped whipped cream! :) Most sea creatures that create these kinds of valueless pearls include edible oysters, edible pearls, escargot snails and more.

Answer 4

The general method of cultivating pearls is to grow oysters on "strings" in a cage submerged in a "farm plot" in the ocean until they are large enough to be worked with. Then they are opened carefully and a seed (a round "blank") is inserted in a specific location inside the oyster. (This is called seeding, naturally.) The oyster sees this seed as an irritation and covers it with nacre. By using a seed as a "starter pearl" inside the oyster, the creature doesn't have to build a whole pearl from scratch. The seed, which is usually made out of fresh water clam shell, can be covered with nacre in just a couple of years. The oyster is pulled up after that time, the pearl is removed and the (now larger) oyster is reseeded with a larger "blank" and allowed to grow another pearl. The oysters can live some 10 to 12 years like this, delivering a pearl every couple of years. Use the link below for more information.

Answer 5

None of them. Pearls are produced by bivalve muliscans (oyster) or clams.
