Press Release Summary: Unlike other gems such as precious stones that are cut and
polished in order to reveal their hidden beauty, many believe that pearls are
harvested and presented in their natural state without any enhancing treatments. In
reality, this is not the case. Nearly all pearls harvested and sold today undergo
some form of pearl treatment.



Press Release Body: Pearl Polishing



Unlike other gems such as precious stones that are cut and polished in order to
reveal their hidden beauty, many believe that pearls are harvested and presented in
their natural state without any enhancing treatments. In reality, this is not the
case. Nearly all pearls harvested and sold today undergo some form of pearl
treatment.

One treatment common to most harvested pearls is pearl polishing. Pearl polishing
was not too common 20 years ago, but today has become standard practice in order to
enhance the natural beauty, surface quality and luster of most pearls. The polishing
process consists of an initial tumbling and cleaning process that removes various
natural deposits and residue that might cause irregularities in the pearl surface as
well as sea-borne odors. Next the pearls may be tumbled again with various natural
materials such as bamboo slivers to further smooth out imperfections in the pearl\'s
surface.

Though these processes are rather benign and do not decrease the quality of the
pearl, some practices that include infusion of oily substances to help increase
luster are frowned upon by National Pearl. Such practices only increase luster
temporarily, fading with time and wear.

Almost universally frowned upon is the practice of coating lower quality pearls with
various luster-increasing epoxy resins. While such materials do increase luster
dramatically, they are prone to chipping and cracking over time, eventually
revealing the low quality pearl surface. One way to detect such treatments is to use
a loupe to closely inspect the pearl's surface. Often, imperfections in the epoxy
coating that are not visible to the naked eye will become visible after
magnification. National Pearl does not employ any form of luster-increasing
post-treatments such as oily coatings or epoxy resins on any of our pearl products.



Pearl Bleaching



Another common practice within the pearl industry is called pearl bleaching. The
pearl bleaching process is often employed after the initial cleaning process in
order to help even out color irregularities within the top layers of pearl nacre.
The forms of bleach used are very mild, allowing gentle lightening of the pearl
nacre without damaging pearl nacre quality.

While the vast majority of white pearls on the market today have undergone some form
of mild bleaching, the practice is not commonly disclosed and is often denied by
pearl farmers and distributors. National Pearl believes that educating our customers
is far preferable to deception and hopes to make the full and honest disclosure of
pearl industry practices the basis of long-term relationships with our clients.



Pearl Color Enhancements



Some of the most common form of pearl treatments today include color enhancing
treatments. Pearl color treatments are employed today in order to help satisfy the
variety of requirements from the pearl purchasing public. For example, Akoya pearls
harvested from their oysters come in one basic body color: white. The pearls may be
naturally accented by a few gentle overtones such as rosé, silver or green.

Customers around the world have different tastes and preferences when it comes
to body color and overtones. How then are these pearl color preferences
satisfied? The answer is color enhancement of one form or another.

The most common form of pearl color enhancement is dyeing. Pearls are dyed after the
drill holes have been completed. As such, if pearls are presented to a buyer as
"natural color", an easy way to discover the truth to such a claim is by examining
the drill holes with a loupe. A build-up of the dye is often detectable at the
surface of the drill hole revealing which pearls have undergone a dyeing treatment.
Another way to detect pearl color enhancements is to simply evaluate the overall
matching of a strand. If you are examining a strand of pearls that exhibits an
exotic color and the matching and surface seem all too perfect, yet the pearls have
an exceptionally low price, the chances are that the pearls have been color enhanced
in one form or another.

It is important to note that pearl dyeing is not frowned upon in the pearl industry.
On the contrary, it is quite a common practice. What is important is full disclosure
of the various treatments a pearl has undergone. Every client has the right to
understand what treatments a pearl has undergone from the time it leaves the oyster
until the time of their purchase. Unfortunately, the many "middlemen" that
participate in the pearl trade may not receive honest disclosure from the pearl
farms concerning the various pearl treatments that have been employed on their
pearls. As a farm-direct purchaser of pearls, National Pearl has full access to
pearl treatment information and freely discloses such information to our customers
immediately upon request.
