  • Freshwater Pearls

    Freshwater Pearls Defined

    Freshwater pearls are pearls which grow in non-saline environment in freshwater mussels.



    Freshwater Pearl Grading There currently is no internationally recognized grading standard for freshwater pearls. Every system in use is subjective and unique to the company or organization that creates the system. The Chinese government has begun work on a system, but the tremendous number of variants strongly discourage adaptability. In additi...

  • Choosing the Perfect Pearl Necklace for You: Length and Size

    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 pearl...

  • VI. Common Mabe Pearl Varieties - Abalone Mabe
    by CortezPearls
    C. Abalone Mabe (Genus Haliotis)

    Abalone (or “Ear-shells” as they are sometimes referred) are not pearl oysters at all; they are, instead, an ancient group of marine “snails” known as Archaeogastropoda (Ancient belly-crawlers). Because they are snails, they move about their environment, living on rocks and grazing on brown seaweeds (kelp). Another interesting difference with pearl oysters is that these animals have a temperate water affinity: they prefer cold...

    B. Mother-of-Pearl Oysters (genus Pinctada)

    Black Lip Pearl oysters (Pinctada margaritifera)

    Black lip pearl oysters are known mainly for their beautiful, dark, cultured pearls but they have also been used to produce Mabe pearls, although in not great numbers.

    Part of the production strategy for Mabe pearls in French Polynesia and Fiji is at the very last part of the pearl producing cycle:
    Cultured (loose) pearls are produced for up to three cycles (first,...

  • VI. Common Mabe Pearl Varieties - “Rainbow Lipped Pearl Oyster”
    by CortezPearls
    “Concha Nácar” or “Rainbow Lipped Pearl Oyster”

    This species of pearl oyster (Pteria sterna) has been used to produce both cultured loose pearls and Mabe pearls in Mexico. The first Mabe pearls were obtained back in 1994 and were the main product for the Guaymas based pearl farm until loose cultured pearls became more common (2002). Since 2010, “Cortez Mabe” have been produced in a steady number between 1 to 5-thousand pearls per year. There is an experimental Mabe pearl...

  • VI. Common Mabe Pearl Varieties - A. Winged Pearl Oysters (genus Pteria)
    by CortezPearls
    There are several varieties of commercially grown Mabe Pearls that can be found at jeweler’s displays or on online vendors, but many have become rare over the years. The three main sources for Mabe pearls today are:
    1. Winged Pearl oysters from genus Pteria, including the “original” Mabe-gai (Pteria penguin) and the “Rainbow-lip” pearl oyster (Pteria sterna).
    2. Mother-of-Pearl oysters from genus Pinctada, mainly from the larger Silver (Pinctada maxima) and Black (Pinctada margaritifera) lipped pearl

  • V. Processing Mabe or Natural Blisters
    by CortezPearls
    Since these pearls are not very useable in jewelry with the entire shell, they are processed: first they are cut from the shell, with the help of a handsaw, Dremel tool, core-drill or tile cutting saw. The type of tool will depend on availability and production volume, the first used mainly by occasional processing and the latter for commercial production.

    A lineup of the Mabe pearl process.

    Once the blister is separated from the shell, these are rinsed to remove grime,...
