How to evaluate natural pearls

Natural pearls are generally viewed as the rarest and most precious type of pearl. Because it involves greater labor and technique in the process of finding, matching and turning them into jewelry than the other two types of pearl. Unlike the cultured pearls, natural pearls are created by nature instead of being seeded and made in a factory. Then how to tell the difference between the natural pearls and cultured pearls? Here we talk something about it.
Apply a magnifying lens to check the pearl closely. Try to verify the thickness of the "nacre." The nacre of a pearl is the shiny mother-of-pearl layer surrounding the core of the pearl. In cases where the pearl did not develop evenly, you can sometimes see the core of the pearl through the nacre.
Look at your reflection. If the luster of a pearl is rich, you will be able to see your reflection in the surface of the pearl. The lower the quality of luster, the lower the quality of the pearl. A low-quality or imitation pearl will appear dusty and flat instead of shiny and reflective.
Check the degree of symmetry and spherical shape. Natural pearls are very seldom perfectly round, but symmetry is highly prized. It's best if the pearl is close to being completely round.
Check for flaws and blemishes. Blemishes on a pearl include discolorations, uneven surface texture, bumps, and dents in the surface of the pearl. All these are different from the overall beauty and luster of the pearl. It is highly unusual to find a flawless natural pearl, but the blemishes should preferably be invisible to the naked eye.
Never look at the pearls in the proximity of the color red. Because red makes pearls appear to have a thicker nacre, rich luster even if, in fact, the pearl has a low quality.
The above tips all help you evaluate natural pearls. If you still cannot make sure the pearl is natural or not, take it to a jeweler or a pearl expert. Don’t spend your large money on the fake pearl jewelry anyway.
