How Do Pearls Become Pearls
The formation of a pearl takes years. The first step is the growth of a nacreous layer around the nucleus which takes several months. The second stage is the development of the shell around this layer which requires another year.
Finally, the third stage is the maturation of the pearl itself, which lasts up to 20 years. Pearls are an incredibly unique gemstone. While most precious gems are formed in the ground, surrounded by rocks, pearls are the only gemstone created inside a living creature.

How Long Does It Take for A Pearl to Form?
A pearl forms when water touches the shell. A pearl is formed from minerals and organic matter which are dissolved into the surrounding seawater. The process takes several years before the shell becomes hard enough to protect the pearl inside. Once formed, pearls usually remain intact until they are taken out of the ocean. They are then cleaned, polished, and sold.
The formation of a pearl depends on many factors including the size of the oyster, its diet, and the amount of oxygen available in the environment. In addition, the temperature of the surrounding water affects how quickly the mineral deposits form around the nucleus.
Pearl production occurs naturally in the wild. However, most people who collect them do so intentionally. Pearls are collected during their natural maturation period, which varies depending on the species. Some types of pearls mature faster than others. For example, some species of oysters produce pearls at a rate of one per year while others produce up to 100 per year.
Most pearls are produced by members of the genus Pinctada. This includes the common black-lip pearl (Pinctada margaritifera) and the green-lip pearl (P. maxima). Other species include the Pacific white-spotted (P. albiflora), the pink (P. fucata), the Japanese black-lip (P. japanica), and the Chinese black-lip (Pinctada imbricata).
How Do Oysters Form Pearls?
Oysters are bivalve mollusks, which means they have two shells. The outer shell is called the mantle and the inner one is called the operculum. They live in shallow waters around the world. In some places, like the Gulf Coast, there are many oysters. There are different types of oysters. Some oysters eat plants and others eat dead animals. Some oysters are edible while others are poisonous.
There are three main ways that oysters make their pearl. First, they use calcium carbonate from their food to build up their own shells. Second, when they are mature, they release mucous into the water. This makes them sticky so that they stick together. Finally, if they get enough pressure inside their body, they can push out a small piece of themselves. This piece becomes a pearl.
The pearls’ formation process is quite mysterious. To those not deeply versed in the process, it may appear to be a little bit like mother earth’s magic. Indeed, it is. How does this seemingly mundane little creature turn into an exquisite sphere? Like many natural phenomena, the creation of a beautiful gemstone takes time. But once the process is complete, it results in something breathtakingly gorgeous. In this article, we’ll answer all your burning queries about how a gemstone is made.
How Do Oysters Make Pearls
Oysters are mollusks that live in saltwater environments. They filter food from water through their gills. The shells they use to protect themselves are called exoskeletons. When these shells break down, the soft tissue inside them becomes part of the pearl. This process takes place when the oyster dies and its body breaks down.
The formation of a pearl begins when the nucleus of the egg cell divides into two cells. One of these cells forms the inner layer of the shell while the other forms the outer layer. Once the shell has formed around this nucleus, the mantle secretes nacre onto the surface of the shell. Nacre is made up of calcium carbonate and organic material. It grows very slowly, so it takes several years before a mature pearl is produced.
After the shell has been covered in nacre, the nucleus continues dividing until there are hundreds of nuclei inside the shell. Then the growth of the pearl slows down. At this point, the nucleus stops dividing and the pearl starts growing. After many months, the nucleus finally reaches maturity and the pearl is ready to form.
Once the nucleus has reached maturity, the pearl starts forming. First comes a cap, which is a hard substance that protects the nucleus. Next comes the nucleus itself, which contains thousands of tiny crystals. Finally, the nucleus splits open and the seed crystal falls out. If the nucleus was large enough, the seed crystal would fall directly into the center of the cavity. However, if the nucleus was small, the seed crystal might get stuck at one end of the cavity. In either case, once the seed crystal has fallen out, the next step is to grow the rest of the pearl.
When the seed crystal drops into the cavity, it attaches to the bottom of the cavity and begins to grow. The first thing to happen is that the nucleus pushes against the bottom of the cavity. This causes the cavity to expand slightly. Then the nucleus begins to push the surrounding nacre away from the bottom of the cavity, causing the nacre to start growing outward. This process continues until the entire cavity is filled with nacre.
As the nacre grows, it gets thicker and harder. Eventually, the nacre completely covers the seed crystal. Now the pearl is finished!
The Birth of a Pearl
Oysters make pearls in response to an irritant, such as a grain of sand or another object. When any irritant makes its way between the mollusk’s shell and mantle, the creature produces nacre, a protective coating that helps reduce irritation. Nacre is also referred to as mother-of-pearl; it’s made of microscopic crystals of calcium carbonate, and it also lines the interior of a mollusk’s shell. Layers of nacre coat the irritant, eventually forming an iridescent gem (the pearl).
The only difference between naturally developed pearls and cultured pearls is that, with cultured pearls, a pearl farmer embeds an irritant between the shell and the mantle by cutting into the mollusk’s tissues. With freshwater pearls, irritants do not need to be introduced. S imply cutting the oyster’s soft tissues is enough to begin the pearl-making process.
How Long Does it Take to Make a Pearl?
Once the irritant has been planted, how long does it take for a pearl to form? Some pearls can develop in a period of six months. Larger pearls can take up to four years to develop. This is one of several reasons why larger pearls can yield higher values.
Harvesting Pearls
Pearl farmers must have immense patience to wait for a pearl inside an oyster shell to develop. When a pearl in an oyster is ready, the harvester opens the shell, extracts the pearl and evaluates it for quality. Some oysters can produce two to three pearls over the course of their lifetime, but only an oyster with pearls of good quality will repeat the process of producing a pearl.
