    PEARL FARMING

    The first step in the pearl

    production process is to

    obtain pearl-producing

    oysters to be nucleated.

    The pearl farmer collects

    oyster sperm and eggs

    from high-quality oysters

    already on the farm. The

    sperm are used to fertilizethe eggs, and so create a

    new generation of oyster

    larvae. Over a period of a

    few months, the larvae

    develop into baby oysters.

    They are generally then

    moved into a separate

    "nursery" area of the farm.

    Here they are tended for

    around 1-2 years, until

    they have grown

    sufficiently large to be

    nucleated.

    PEARL FARMING

    Creating the pearl nucleus. The nucleus used in all

    saltwater pearl farming today is a mother-of-pearl bead.

    This bead is composed of mussel shell that has been cut,

    rounded, and polished.

    A nucleus of high qualitywill be white, without

    calcium carbonate

    streaking (striation or

    banding), that may show

    through the pearl nacre.

    PEARL FARMING

    The process of nucleation is

    a surgical procedure,whereby a foreign object is

    implanted into the oyster.

    This object causes irritation,

    which the oyster

    counteracts by secreting

    nacre to surround theobject; this produces the

    pearl. The mother of pearl

    nucleus is inserted into this

    incision, which is then

    followed with a very small

    piece of mantle tissue froma donor mollusk. The mantle

    tissue is placed between the

    mother of pearl bead and

    the gonad, with the side

    containing epithelial cells

    facing the nucleus.

    PEARL FARMING

    Pearl Harvest: Akoya

    cultured pearls areharvested from the pearl

    farm after a nucleation

    period of 18 months to 2

    years. A good harvest is

    determined by the number

    of marketable pearls

    produced in relation to thenumber of oysters that were

    nucleated.

    On average, only half of the pearls

    will be marketable, and less than

    10% of these will be considered

    top-quality.
