    Cultured Pearls Defined

    A cultured pearl is any pearl grown with the influence of human intervention.

    Cultured Pearl Formation

    A pearl is formed when a small irritant or parasite penetrates and lodges in the mantle tissue of a mollusk. In response, a substance called nacre is secreted, and the creation of a pearl begins. Nacre is a combination of crystalline and organic substances. The nacre builds up in layers, as it surrounds the irritant to protect the mollusk, and after a few years, this buildup of nacre creates a pearl.

    Natural Pearls vs. Cultured Pearls

    Natural pearls are pearls formed by chance. Cultured pearls have been given a helping hand by man. Today, nearly all pearls are cultured. By inserting a foreign object into a mollusk, pearl farmers can induce the creation of a pearl. From there, the same process of natural pearl creation takes place. The difference is that in this case, the inducement is intentional.

    Most cultured pearls can be distinguished from natural pearls using x-rays, which reveal the inner part of the pearl.

    The Early Days of Cultured Pearls

    Harvesting cultured pearls from the oyster. Modern-day cultured pearls are the result of discoveries made in the late 19th and early 20th centuries, by Japanese researchers Tatsuhei Mise, Tokishi Nishikawa, and the son of a noodle maker, Kokichi Mikimoto. Although some cultures had long been able to artificially stimulate freshwater mollusks into producing a type of pearl, the pearls produced in this way were hemispherical Mabes, rather than completely round pearls.

    Finally, Producing Round Cultured Pearls

    While early on in Mikimoto's career he focused on Mabe production, he eventually produced rounds with a technique involving tissue and bead insertion into the gonad of an akoya mollusk. He patented this technique in 1916.

    The Cultured Pearl Industry is Born

    This revolutionized the pearl industry because it allowed the reliable, consistent cultivation of large numbers of quality pearls. The cultured pearl industry of today was born. While natural pearls have widely varying shapes, sizes, and qualities, and are difficult to find, cultured pearls could now be "designed" round from the start. High quality, round pearls could now be produced by the millions, making them available and affordable to everyone.

    Today's Cultured Pearl Industry

    The development of pearl culturing took much of the chance, risk, and guesswork out of the pearl industry. It has allowed it to become stable and predictable, fostering rapid growth over the past one hundred years. Today, the cultured pearl industry has replaced the natural pearl industry with production of cultured freshwater, South Sea, Tahitian, and of course Mikimoto's original Akoya pearls.

    • The Genus Pteria Scoppoli 1777
      by CortezPearls
      The family Pteriidae is composed of three or four genera, and pearl oysters belonging to the Pinctada and Pteria genera are -of course- the most important from our point of view.

      Taxonomy

      An old name for this species is Magnavicula, which means “Large Wing”, with the “new” -Pteria- name originating after the Greek word “Ptero” which translates into “wing”, hence the name of “Winged oysters”.

      These species are identified by...

      Sustaining Life with Pearl Farming

      One of the most important aspects of pearl farming is its inherent ability to protect and create more life than the one that was available previously. And what do I mean by this? When you start a pearl farm in a location, you begin with a resource that has already been “pillaged & plundered”, probably for hundreds, if not thousands, of years. As an example, we have the pearl fisheries of the Persian Gulf -whose pearls were adorning...

      ENVIRONMENTAL AND SOCIAL IMPACT OF THE CCCP

      There was a positive ecological aspect of this venture: the pearl farm itself acted as a gigantic breeding station for the pearl oysters. When you consider that this farm contained between 8 to 10 million pearl oysters and let us say that at least one-third of these had reached ****** maturity (2.6 to 6.6 million individuals), it is very evident to see the astounding positive impact that this commercial operation would have in restocking...

      THE FIRST COMMERCIAL PEARL OYSTER FARM IN THE WORLD

      It is at this particular crossroad that we find a Mexican-French Medical Doctor by the name of Gastón Vivès, attempting what very none had tried before: initiate a commercially viable, large-scale pearl oyster farm to produce shell and pearls. The Vivès family owned a pearl fishing armada in La Paz, Baja California Sur, and they were experiencing diminishing profits every year, thus wanting to revert this trend we find Gastón Vivès...

      The arrival of the Iberian Conquerors

      The Native Nations had no real interest in establishing a commercial venture in pearl fishing and we understand little to nothing of the way they fished for pearls, since most of the information was either lost or destroyed during the conquest of Mexico. The rich plunder of the Conquistadores was sent to Spain and later dispersed all over Europe. The most significant information we have on the subject comes from the period of colonization of northwestern...

      A review: The History of Pearls in the Gulf of California, Mexico
      By Douglas McLaurin-Moreno


      Since unrecorded time, man has obtained many bounties from the world’s oceans: food, shells, corals, sponges, seaweeds, and the most desirable of all of these were the beautiful mother-pf-pearl shells and their valuable treasure, Pearls.

      Mexico has four species of pearl oysters inhabiting its coasts, two -the larger sized- on the Pacific side: the Panamic Black Lip...
