A pearl originates when a small irritant or object is placed within the tissue of a mollusk or oyster. In response to this process, the mollusk or oyster releases a nacre. A nacre is a mix of organic and crystalline substances. As the layers of the nacre begin to build gradually, eventually it will form a pearl when it is surrounded by the irritant.

Cultured pearls are the ones that are given a helping hand by a human. While natural pearls are the ones that are formed by nature. By inserting a foreign object into the tissue of the mollusk or oyster, pearl farmers are given the ability to induce the pearl creation. Don’t let this statement fool you, the natural creation of a pearl still does occur. The only difference is that with the production of cultured pearls, the creation of the pearls are not accidental. Natural pearls are formed more or less by chance, by a piece of food or a parasite lodging itself within the gonad or muscle tissue of the oyster.

Japanese researchers have made quite a few discoveries in the late 19th and early 20th centuries that ended up resulting in the production of the modern-day cultured pearls we are able to see produced to this day. Certain cultures have long been unable to artificially stimulate a freshwater mollusk in order to produce a type of pearl. A remarkable discovery would have to be one by Kokichi Mikimoto that suggested a specific technique for releasing the creation of a round pearl within the tissue of an oyster.

That certain discovery made by Kokichi Mikimoto modernized the pearl industry. The reason for this modernization was because it gave pearl farmers the ability to cultivate large amounts of high-quality pearls in a reliable manner. Unlike the natural pearls that have a wide variety of shapes, sizes, and characteristics, the cultured pearls can be designed from the beginning to be round and flawless for the most part. To better serve the health and survival of the oysters, the ability of monitoring these oysters during the several years that they produce, is an ability that pearl farmers can find to be quite useful. The accessibility of pearls for a large amount of people around the world is a good example of the effect of pearl farmers having the ability to grow tens of thousands of pearls.

The history and modernization that cultured pearls hold is a rather interesting subject when dealing with pearls. It is miraculous how far the pearl industry has came over time. Usually, cultured pearls can be identified against natural pearls by being placed within x-rays. Placing pearls in an x-ray will reveal the nucleus that lays within the pearl.
