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
Preparation ofmantle tissue taken from a donor oyster. The nucleus
and mantle tissue are then implanted into the oyster's gonad.

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.
