Pearl Types
Freshwater
PearlsFreshwater pearls are best
known for their wide range of shapes, sizes, and colors, and their
attractive prices. They are produced by the Hyriopsis cumingi
mussels, which live in lakes and rivers in remote areas of China.
The mussels are nucleated with tiny pieces of mantle tissue, resulting
in pearls made of solid nacre. Roughly the size of a human hand,
these prolific mussels are able to produce up to 50 pearls at a
time, densely clustered on each shell.
Saltwater
Akoya Pearls - - - - - - - - - - - - - - - - -
Akoya pearls are treasured for their
true roundness and reflective shine. They come from
a small Japanese oyster that produces only one pearl at a time.
The saltwater Pinctada fucata oyster lives along the coasts
of Japan and China. A nucleating bead is surgically implanted in
the body of the oyster, who coats it with layer upon layer of beautiful
nacre. These relatively small pearls range from 2 to 10mm; Akoyas
larger than 8mm are quite rare and valuable.
Tahitian
Pearls & Black South Sea Pearls - - - - - -
Tahitian pearls are the only pearls in the world that are naturally
black. Rare, exotic, and luxurious, Black South Sea pearls are produced by the
Pinctada margaritifera oyster, native to Tahiti and the
French Polynesian islands. These saltwater oysters can grow as large as a dinner plate, resulting in pearls that range from 8 to 18mm in size! Tahitian pearls come in a mesmerizing array
of colors, from silver to deep black, with shades of green,
blue, and pink.
White
South Sea & Golden South Sea Pearls - - - -
White South Sea and Golden South Sea pearls are treasured for their
luxurious size and brilliant satin luster. These valuable pearls
are produced by the famous silver-lipped oyster, Pinctada maxima,
along the coasts of Australia, Indonesia, and the Philippines. As
the rarest pearls on earth, a single strand of these magnificent
gems can take many years' of harvests to assemble, as each pearl
must be painstakingly matched for size, roundness, color,
and quality.
Mabe
& Half Pearls
Mabe pearls are hemispherical cultured pearls grown against the
inside shell of an oyster, rather than in the body. They are typically
used in settings such as earrings or rings to conceal their flat
backs. Mostly produced by saltwater oysters, Mabe pearls are grown
in Japan, Indonesia, French Polynesia, and Australia. These "half
pearls" range from light pink to bluish in color. Although
they are beautiful, they do not retain nearly as much value as full
round pearls.
Imitation
Pearls
Imitation pearls are manufactured by humans and have no true value.
They are often sold under misleading names, such as faux
pearls, Mallorca pearls, organic, or simulated pearls. An experienced
jeweler can distinguish between real and imitation pearls by examining
the drill hole or taking x-rays. An easy way to tell the difference
is the "tooth test". An imitation pearl rubbed against
your teeth will feel smooth and glossy, while a real cultured pearl
will feel gritty.
