  • The Genus Pteria Scoppoli 1777

    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...

  • Tahitian Pearls

    Tahitian Pearls Defined

    Tahitian pearls are bead-nucleated pearls grown in the gonad of the Pinctada margaritifera mollusk in French Polynesia.



    Tahitian Pearls - Among the Most Beautiful in the World

    Tahitian pearls are produced in the black-lipped oyster Pinctada margaritifera, in and around Tahiti and the French Polynesian islands. This oyster itself is quite large - sometimes over 12 inches (30 cm) across and weighing as much as 10 pounds (4.5...

  • Cultured Pearls

    Cultured Pearls

    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...

    A review: The History of Pearls in the Gulf of California, Mexico Part 4

    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...

    A review: The History of Pearls in the Gulf of California, Mexico Part 3

    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...

  • Debunking a Widely Held Japanese Myth

    By C. Denis George Abstract by Anna Kerrig

    Historical Aspects on the Early Discovery of the Pearl Cultivating Technique Japanese scientists, Nishikawa and Mise are typically recognized for discovering the technology that led to cultivating spherical pearls. C. Denis George was an Australian enthusiast who challenged the credit given to the Japanese for this discovery. George argues that Nishikawa and Mise's step-father were first exposed to successful pearl cultivation at Thursday...

  • Natural Pearls

    Natural Pearls Defined

    Natural pearls are calcium carbonate secretions which form within mollusks without human intervention.



    Natural Pearls - Accidents of Nature Natural pearls are formed randomly and really are simple accidents of nature. When a certain type of irritant, such as a parasite, becomes lodged in the tissue of a mollusk, the animal responds by secreting a calcium carbonate substance called nacre to coat the intruder and protect the mollusk...
