Pearls are elegant jewelry. You can buy them shaped as necklaces, bracelets, earrings or even as an accent to a ring. There are hundreds, if not thousands of pearl jewelry designs to choose from in the market today. Before you buy one for yourself, you should learn how to identify if what you are getting is genuine or fake.
First, you have to know the kind of pearl that is available in the market. They are categorized in two:
1. Saltwater pearls - these are formed inside oysters that are living in the heart of the ocean. It has three types - Tahitian, Akoya, and South Sea Pearls - depending on the kind of oyster that produced it.
2. Freshwater pearls - these are formed inside mussels that are living in lakes, rivers, ponds, or any other body of fresh water.
Either saltwater pearls or freshwater pearls can be natural or cultured. Natural means that there is no human intervention and the pearl is formed naturally by the oyster or mussel. The pearl oyster secretes nacre an iridescent material made of calcium carbonate. The nacre will coat a microscopic irritant entering its shell until a pearl is formed. On the other hand, cultured means that a pearl grower will carefully open the shell and introduce a small object as an irritant (commonly a bead or metal), then get them back into the water and wait for the pearl to form. This usually takes 2-5 years.
There are a lot of fake pearls out there, but it is more pleasant to own a genuine pearl jewelry at least once in your lifetime. A genuine pearl does not only mean "natural". Even "cultured" pearls are genuine pearls too, having an advantage of being more affordable than natural pearls.
When you hear of fake pearls, it means that they are man-made pearls made of glass, ceramics, plastics or any other similar materials. They are also called "faux" pearls and are sold as costume jewelry. In the face of modern technology, man can create pearls that look like the original one. Mind you, fakes can have the exact original look, but they do not have the same weight or texture. And their luster is dimmer, which is enough to show that they are imitations of the original. They do not contain any gem value.
To help you with identifying genuine freshwater pearls, here is a three way test:
1. Tooth test - get the pearl and run it against your front teeth, just right below the biting edge. If you sense a gritty feeling, it is most probably real. Fake pearls are smooth, like plastic or glass. However, be very careful of the pearls that are made from ground shells as they can also be gritty.
2. Luster test - test the pearls against all kinds of light. Fake pearls will have a shine only on the surface, while genuine pearls always shine from within.
3. Rub test - get two pearls and rub it together. It should be gritty and do not slide off each other.

Appearance
The interior of the shell of this species has thick nacre. The species is capable of making fine quality pearls, therefore it was historically exploited in the search for pearls from wild sources.
The shell of Freshwater pearl mussel is very thick and heavy, elongate, oval and shaped like a "kidney" [compare with the Thick shelled river mussel]. Shell reaching a total length of 10 - 15 cm and a height of 5 ? 7.5 cm. The color of Freshwater pearl mussel is dark brown-black, to blue and black. The Freshwater pearl mussel has got hinge-plate with anterior lateral and cardinal teeth, one in the left valve and two in the right valve. These injuries are often of yellow color caused by keratin. There is a possible risk of confusion between the Thick shelled river mussel and the Freshwater pearl mussel. The difference in the shape of the hinge-plate is a distinct feature when separating the two species.
Life History
The freshwater pearl mussel is one of the longest-lived invertebrates known, and individuals can survive for over 100 years. The Freshwater pearl mussels live buried or partly buried in coarse sand and fine gravel in clean, fast-flowing and unpolluted rivers and streams. They inhale water through their exposed siphons to filter out minute organic particles on which they feed. Where the species was formerly abundant, it is possible that this filtration acted to clarify river water to the benefit of other species.
Status
Today in waters easily accessible to human, almost no wild Freshwater pearl mussels are found in rivers or streams any more. A further problem is the acidification of the water because of acid rain.
Rehabilitation attempts must ensure that water quality is high and that healthy populations of young salmonid fishes are present to provide potential hosts. In Germany and UK, sewage effluent and farm drainage diversion has been used to protect one abundant stock. Translocation of adults of Freshwater pearl mussel doesn't show to be effective and anyway would reduce the donor stocks. The best strategy is to try to protect existing adults from further fishing and to ensure optimum habitat conditions for the Freshwater pearl mussel.
