AKOYA
PEARLS Akoya pearl
is a cultured saltwater pearl that come primarily from Japan
and China. Size ranges from 2mm to 10mm, and is used in most
of the necklaces found in retail stores. Common Akoya
colors are white, yellow, pink and cream and are found on
the outer edge of the pearl. Pearls are characterized by
their translucence and lustre and by delicate play of
surface colour called orient. The more perfect its shape
(spherical or droplike) and the deeper its lustre, the
greater is value. FRESHWATER
PEARLS A great irony
of pearl history is that the least expensive cultured pearl
product in the market today rivals the quality of the most
expensive natural pearl ever found. Natural feshwater pearls
occur in mussels for the same reason that saltwater pearls
occur in oysters. Foreign material, usually a sharp object
or parasite, enters a mussel and cannot be expelled. To
reduce irritation, the mollusk coats the intruder with the
same secretion it uses for shell-building, nacre. Most cultured
freshwater pearls are composed entirely of nacre. Japanese
pearls farmers experimented with freshwater mussel in Lake
Biwa, a large lake near Kyoto. Initial commercial freshwater
pearls cropss appeared in the 1930's. The all-nacre Biwa
pearls formed in colors unseen in saltwater pearls. Almost
instantly appealing, their lustre and luminescent depht
rivaled naturals because they too, were pearls
throughout. TAHITIAN
PEARLS The black
Tahitian pearl is produced by the Black Lipped oyster
(Pinctada Margaritafera) which is found in the waters of
french Polynesia, Natural Black Tahitian pearl are extremely
rare since only one of about 10.000 oysters contains a
pearl. Most of the
pearls farms are in the Tuamoto and Gambier island groups.
The shape, color, and luster of these certified cultured
black Tahitian pearls are natural. The tahitian
pearls range in size from about 8 mm to about 25mm in
diameter which is the size of the largest black tahitian
pearl ever found. Black Tahitian pearls 12mm in diameter or
larger are considered to be rare. Most black
Tahitian pearls are not really black. Colors can be light
silver, gray, yellow bronze , green with pink overtone, and
peacock nearly all colors showing in play-of-color on the
surface of the pearl. Click to enlarge the
