Real vs. fake pearl beads
The two real pearls and imitation pearls can be beautiful, but sometimes it is important to know which type you have. When buying pearls, you may be able to identify fake pearls by their name: synthetic fake, simulated, fake, glass, plastic, synthetic resin, artificial. There are different types of real pearls. There are pearls and cultured pearls. Real pearls may come from freshwater (rivers, lakes, ponds) or salt water (sea or salt marshes) and a variety of shellfish. To complicate things, there are pearls that are partly natural and partly of human origin. There are real pearls and pearl shells that have had treatments that are applied as coatings or faceting. Here is a list of tests you can use to distinguish between real pearls, and all the various counterfeits.

Methods to tell real pearls from fake pearls

• Destructive Testing
  If you cut a pearl open, you can see his true nature. Natural pearls are composed of layers of nacre. Cultured pearls have a shell (mother of pearl) core covered with a thin layer of nacre (generally no more than half a millimeter, usually much thinner). faux pearls have a nucleus with one or more layers of coating applied to them, which tends to flake away from the base of the cup. Cutting a pearl reveals the nature of its hole, if present. Of course, you should be able to tell pearl-colored glass shell to do this test (plastic and resin are easier to discern). Also, you destroy the pearl. It is not recommended.
• X-Ray
  If you really need to know whether or not your pearls are real or false, or whether they are natural or cultured, you'll have to pay someone, preferably a certified gemologist, to x-ray them for you. A radiograph showed the interior of the pearl, including variations in its density, the presence or absence of a parasite that may have caused the formation of a natural pearl, and the characteristic shapes of drill holes, the appropriate.
• The test of the tooth
  Let me begin my remarks by stating an important point: this test is not reliable! To use the tooth test, you rub the surface of the pearl on your teeth. Assume a real pearl feels gritty while a fake Pearl is smooth. The premise behind the test is valid: real pearls are composed of layers of nacre that are deposited as a bit of sand on a beach. The light waves and irregularities in the nacre can produce a rough or bumpy feeling against the teeth. On the other hand, many types of synthetic mother of pearl are applied gently on pearls perfectly smooth. These pearls would feel smooth against the teeth. The test is very good for distinguishing rare natural pearls from glass pearls, but it is not as good at identifying cultured pearls, which have fewer layers of nacre and may feel more smooth. If the pearls are dyed, the dye can fill in natural depressions in the pearls, making them feel good. In addition, some synthetic pearls are produced to look and feel like real pearls. Mabe pearls may have a protective coating applied to them, making them smooth, even though they may be genuine. The formulation of the nacre may resemble that of real pearls. The mother can be applied to a natural base, like a shell bead, making this test completely unreliable. The tooth test is a test from Nice, but do not base your judgments of the authenticity of this test only. If you think it's reliable, I swear I could find pearls fool you, both real and fake.
• Test Sun
  This is my favorite test. It involves taking your pearls in the sun or keep them under very bright indoor lighting. UNlTED.
