  • Pearl History Timeline - Part 2

    Rome The Romans acquired their taste for pearls from the Greeks, and for some centuries rivaled or overtook India as the world's biggest pearl depository. There was such competition for pearls in Rome that laws were made that only the elite could wear them. Statues of the goddesses especially Venus wore only the absolute best, largest, and most perfectly matched pearl earrings, in their marble pierced ears. Mortals got to fight over the rest. Large, perfectly matched pairs of pearls were wildly...

  • Pearl-Producing Mollusks (Mollusks)

    Pearl-Producing Mollusks (Pearl-Producing Bivalves)

    Mollusks represent one of the world's earliest forms of animal life, and date back over 550 million years. Actual pearl-producing mollusks first appeared 530 million years ago, when mollusks developed shells. The scientific discoveries of pearl producing mollusks illustrate the intrinsic and irrefutable value of the world's most historically treasured organic gem. Abalone are not bivalves nor part of the "Conchifera" sub-phylum; inste...

    More Famous Pearls from History

    This short list of some of the world's most famous naturals pearls is a continuation from page one.

    Charles I Pearl

    A famous pearl, now lost, destroyed, or hidden away by a discreet collector, was that of King Charles I. Artist Anthony van Dyck (1599-1641) painted several portraits of the king, many of which show a large drop pearl hanging from his left ear. In the portrait, Charles I, King of England, from Three Angles, 1636,...

  • The French Blue by Richard Wise

    I was fortunate enough to get an early Kindle edition of Richard Wise's newest masterpiece "The French Blue". I also own a copy of Wise's "Secrets of the Gem Trade", and it is one of the very few gem books that I've read cover to cover, not just skipping ahead to the sections about pearls. The French Blue is a completely different kind of work. It is a novel that begs to be read slowly, but once one becomes entranced in the story, it is nearly impossible to put down. Not for the faint of heart, i...

  • The Pearl Necklace

    The Pearl Necklace Comes in Many Sizes and Colors The "classic" piece of pearl jewelry is, of course, the pearl necklace. Akoya pearls are the most traditional type of pearl used in necklaces, but freshwater pearls, Black Tahitian pearls, and large South Sea pearls are also used, often to stunning effect. Akoyas, of course, exhibit the traditional white, silver, or cream colors, while Tahitians and South Sea pearls yield pearl necklaces ranging from bright white to darker tones. Freshwater pearls can ...

    Matching can encompass size, color, and quality. A well-matched strand is composed of pearls that complement each pearl above and below, and directly across as the strand drapes.

  • Pearl Luster

    Pearl Luster Defined

    Pearl Luster (also spelled Lustre) is the measurement of the quality and quantity of light that reflects from the surface and just under the surface of a pearl. The word comes from the Latin Lux which translates into "Light".

    Pearl Luster is the Unique Shine that give Pearls their Beauty Luster is the quality or quantity of brilliance of the surface of the pearl. The more lustrous the pearl, the more it shines and reflects light and images. In general,...

    Pearl Grading Defined

    Pearl Grading is the practice of assigning degrees of quality to a pearl or a piece of pearl jewelry based of the quality attributes designated by industry best practices and authority groups such as PSLJ (Pearl Science Laboratory of Japan), SSEF (Swiss Gemological Institute), GIA (Gemological Institute of America) and EGL USA.

  • 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...

  • A review: The History of Pearls in the Gulf of California, Mexico Part 4
    by CortezPearls
    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...
