Today's pearl market is really more and more people can not read, and craft beads done seamlessly, people simply do not see a little flaw. Some with plastic film coating process beads, a good identification, two beads grinding scraping each other, they lost a layer of skin. And some with shells as the core, craft beads coated with paint to identify them on the more difficult. Then, on the identification of natural or cultured pearls, we should grasp what the problem?
     Let us first look shiny. Different pearl iridescence varies. The saying goes, "Whatever You Want", requires a combination of physical carefully taste, Pearl mainly from the pearl out of the internal reflection and diffraction of light generated through the unique luster. Plastic weak reflecting the light abnormal light, but with the glossy coating of craft beads have a false sense of identification carefully.
     Second, to observe the surface characteristics of pearls. surface defects directly affect the number of beautiful pearls, but they will rarely flawless pearls, each pearl a different flaw, just that it is different from other pearls of "birthmarks." To the authenticity of identification provides a basis for the performance of pearl surface defects or ring for the flaw, when the foreign body penetrated between the nacre, the surface will bulge a flaw. 10 times magnifier sometimes need to rely on careful observation, how many will always find some ring phenomena.
     Third, the hand touch. Pseudo-beads are tired of feeling pearl cool dry, hanging around the neck have a cool pleasure.
     Fourthly, you can use dental examination or two pairs of grinding beads, as mentioned above, a pair of grinding on the plastic bead slipping, but will pearls of friction along the teeth of the peaks have a sense of sand, if a good bead, this sense of special sand uniform, feel good, it is because it was composed of nacre crystals arranged in a orderly, just as rugged as the roof panels arranged in neat rows, so friction will make people feel as if playing like sand.
     Finally, you can also test the use of fire, burning, the pseudo-beads and fire and smoke from burning surface color appears, the surface layer of beads fall off, no smoke pearl burning surface color, surface is not well off. However, this method belongs to damage appraisal and should not be multi-purpose.
