  • Pearl Color

    Pearl Color Defined

    A pearl's color is described as a combination of its body-color and its overtone.

    Body colors are separated into two categories: cool hues and warm hues.
    Cool hues range from reddish purple to yellowish green while warm hues range from purplish red to greenish yellow.

    Overtones (also referred to as "Orient") are the overlying color that appears to float over the surface of the pearl.

  • Caring for Your Pearls

    Pearl Care

    Pearls are the world's only organic gem and are composed of calcium carbonate. This means special attention is required to ensure pearls will stay beautiful and last a lifetime.

    Pearls Require Special Care Because pearls are an organic gemstone, they are different from other gemstones and precious metals. They are softer and more delicate, and they can therefore be more easily scratched, cracked, and damaged. In addition, substances such as perfume and hair sp...

  • Nacre

    Pearl Nacre Defined

    Nacre, also known as mother-of-pearl, is a crystalline substance that creates the iridescent visual effect attributed to pearls.
    Nacre is an organic substance secreted by mollusks to produce their shells. It may be used to protect the animal against an intruder (the so called "irritant") or an implanted nucleus in pearl farming. It is a strong and resilient material that is lightweight, reflective and translucent, allowing light to pass through its sur...

  • The Pearl of Allah: The Facts, the Fiction, and the Fraud

    By Caitlin Williams and Kathie Hodson

    The Pearl Millions of dollars, arranged murder, historical fabrications, journeys across vast oceans and battles in court ? all are attached to what some people have called the ugliest pearl in the world. Complex and treacherous like the myriad folds on the surface of the 14-pound baroque pearl (the world?s largest), so too are the tales and trials surrounding the famed Pearl of Allah. Since the day of its discovery, the Pearl of Allah, other...

  • Pinctada radiata

    Naming Problems
    Ever since Shohei Shirahi's book "Pearls and Pearl Oysters of the World" (1994) came out, many species that were once believed to be different have been confirmed as actually belonging to one species. Such is the case for the Pinctada imbricata species, that now encompasses species that were once considered unique to one area. Under this name we now have the former species of "Akoya" pearl oysters: P. fucata, P. martensii, P.radiata, P.anomioides, P.vulgaris, and several others....

  • Scallop Pearls (Pectinidae)

    Scallop Pearls Defined

    A scallop pearl is a non-nacreous calcareous concretion produced by any member of the Pectinidae (scallop) family. Pectinids are known for their uniquely blue colored "eyes" (actually, known as simple-eyes) found in their mantle and for their ability to "swim" using their shells and mantle to create stong "jet-streams".

  • Pinctada maculata ("Pipi" pearls)

    Pinctada maculata (Gould, 1850)

    Distinguishing Characteristics

  • 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...

    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.
