Gemstone Properties
Cultured Pearls
Treasures from the sea
Long known as the “Queen of Gems,” the pearl possesses a history
and allure more compelling than any other gem. In fact, a beautifully
matched strand of natural pearls is a treasure of incomparable
value. Given the incredible rarity of natural pearls, today’s cultured
pearls combine the beauty of nature with the genius of man to
create an organic gem available in a wide array of styles and prices.

Cultured pearls are formed when a small piece of mantle tissue,
a bead, or both is implanted into an oyster. Implanted
material encourages the oyster to begin producing a rich
and luxurious material, called nacre, that creates the pearl’s
lustrous outer glow. Cultivated in both fresh and salt
water, cultured pearls come in many different shapes and colors.
The most popular shapes have traditionally been round,
but more unusual shapes like baroque and button are also
available. Colors range from white and cream to gray and
black, as well as rich purples, golds and yellows.
BIRTHSTONE
Cultured pearl is the birthstone for June.
ORIGINS
Saltwater cultured pearls are produced in the ocean bays,
atolls and inlets of Japan, China, Australia, French Polynesia,
Myanmar, Indonesia and the Philippines. Freshwater cultured
pearls are produced in the lakes and rivers of China
and the United States.
TREATMENTS
Most of the lighter shades of cultured pearls are mildly bleached
to even out their color. Cultured pearls are sometimes tumbled
to enhance roundness. They may be dyed to produce overtones
of pink or strong body colors like teal, magenta or gold.
Occasionally cultured pearls are irradiated to create strong
iridescence or dark hues like black or gray.
CARE
Cultured pearls are softer than most gemstones but durable
enough for everyday wear. Because oils, soaps and chemicals
can damage the beautiful nacre, you should apply cosmetics,
perfumes and hairspray before putting on your pearls. Wipe
your pearls with a dry, soft cloth after each wearing. Never
clean cultured pearls with any harsh chemical, and only use
a commercial jewellery cleaner specifically made for cultured
pearls. The safest cleaning method is using a mild soap and
lukewarm water solution, wiping with a soft cloth.
Always lay strands flat to dry to prevent the cord from
stretching. To ensure years of enjoyment, be sure to have
your cultured pearl strands inspected regularly and re-strung
as needed by your jeweller.
