  • Pearl Farming

    Marine Pearl Farming Defined

    Pearl farming is the industry responsible for growing farm-raised pearl mollusks and producing cultured pearls. These cultured pearls make up nearly 100% of the pearls sold today.

    What Is Pearl Farming? Cultured pearls are grown on what are known as pearl farms. Depending on the variety of mollusk employed at the farm, these will be located in protected bays or in channels or in lakes, ponds or streams (for pearly freshwater mussels). In this cha...

  • Pearl Harvest

    The Pearl Harvest

    The pearl harvest is the pay-off for years of investment and arduous work. The harvest most-often happens during the winter months as the host mollusks' metabolism slows and nacre platelets become thinner as deposition decreases. This has proven to increase the luster upon harvest.


    Pearl Production Times Vary Cultured pearls are harvested from the pearl farms after a period that may stretch from 8 months to 6 years. Akoya pearls are typically c...

  • The Pearl Nucleus

    Pearl Nucleus Defined

    A pearl nucleus is a bead or other object implanted into the gonad of a marine mollusk or into an existing pearl sac in the gonad or mantle of a freshwater mussel around which nacre deposition occurs.



    The Pearl Nucleus and Nucleation/Grafting Pearl farms vary depending on the type of mollusks being produced. But the one thing all pearl farms share is the process of nucleating the mollusks to produce a pearl. Every cultured pearl produ...

  • Pearl Nucleus Composition

    The Proper Pearl Nucleus

    A pearl nucleus is usually made using freshwater mussel shells that has been cut and ground into a polished, spherical bead. Other nuclei do exist, these have been produced from other marine shells, such as from the large black and silver-lipped pearl oysters and from Bironite TM.

    Nacre Deposition will occur over any Solid Object An oyster's "pearl sac" will secrete nacre over nearly any solid object. This has led to countless attempts to nucleate...

  • Pearl Nucleus Manufacturing

    Manufacturing the Pearl Nucleus

    A pearl nucleus is manufactured from freshwater mussel shell which has been worked into a perfect sphere and polished.


    The Nucleus is an Essential part of Perliculture The nucleus of a pearl, although it is not typically visible in a harvested pearl, is extremely important in the culturing process. The nucleus is the seed that the oyster "impregnates" to create and produce the cultured pearl. Without high quality nucleus it is impos...

    The 4000 Year History of Pearls

  • Pearl History Timeline

    Pearl History of Egypt We know that in ancient civilizations, long before recorded history, people adorned themselves with seashells and beads made from seashells. Therefore, it is not surprising that the earliest use of mother of pearl in jewelry occurred in Egypt, about 5,200 years ago. Mother of pearl was used to make cartouches and beads. There are rare examples of pearls in the paintings and statuary of these eras in ancient Egypt, but pearls themselves appear to have been uncommon in these an...

    Pearls have long been attributed with having great powers and have been incorporated into the mythology of every culture that has encountered them. And no wonder! Given the natural pearls' rarity, as well as their mysterious beauty, who could argue that pearls might not indeed be a gift from the gods?

  • 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,...
