Pearls are becoming more and more common in our daily lives. Many female friends like pearl jewelry. However, there are a wide variety of pearls on the market. In addition to real pearls, there are also some fake pearls on the market. These are unscrupulous vendors who want to sell fake pearls as real ones. So how do we distinguish the authenticity of pearls when buying them? Here are some ways to identify the authenticity of pearls. How to tell whether pearls are real or fake? Look at the color of the pearls. The luster of natural pearls is like the seven colors of a rainbow, with many colors but not particularly bright. They have better transparency when exposed to the sun. The surface of artificial pearls is bright and monotonous, does not look very real, and has almost no transparency. The feel of pearls. Natural pearls feel smooth and cool to the touch, while artificial pearls feel warm and creamy. At the same time, you can also gently scratch it with your fingernails, and the real pearls will fall off like fine powder, but there will be no scratches. Artificial pearls will have obvious scratches. And there is no shedding material. Judging from the shape of the pearl. Natural pearls are formed in clam shells over a long period of time by wind and sand, so their shapes are not particularly regular. Fake pearls are usually very round and more exquisitely crafted, but they have no medicinal value. When choosing pearls, we can also pay attention to the holes of the pearls. Fake pearls may have peeling paint on their holes. Friction sound method. You can rub two pearls together. The sound of natural pearls will be like wind and sand, while the sound of artificial pearls will be smooth. The simplest way to identify prices. Natural pearls are generally very expensive. One or two hundred dollars for a pearl. But now there are a lot of pearl powders on the market that cost only ten yuan a bag. Is it true? . I guess everyone knows the answer. . I won’t go into details. The easiest way to identify pearls1. Luster: Pearl luster grade: A ---- Particularly bright, sharp and uniform. The surface is like a mirror, and the image is very clear. Pearl luster grade: B ---- Bright, can reflect the image of objects. Even, the image is very clear Pearl luster grade: C ---- Bright enough to reflect the image of the object. But the image is blurry. 2. Defects: Pearl surface grade: A (flawless) ---- The surface is smooth and delicate when observed with the naked eye, and it is extremely difficult to observe defects on the surface. Pearl surface grade: B (slightly flawed) ---- There are very few defects on the surface, like pinpoints, which are difficult to observe with the naked eye. Pearl surface grade: C (minor flaws) ---- There are smaller defects, which are easily observed with the naked eye. 3. Shape: Pearl shape: A1 (perfect circle) Saltwater pearl: The difference between the longest diameter and the shortest diameter: ≤1% Freshwater pearl: The difference between the longest diameter and the shortest diameter: ≤3% Pearl shape: B (oval) Shaped like a water drop or rice Pearl shape: C (steamed bun) Shaped like steamed bun or bread Generally speaking, whether a pearl is valuable is mostly judged by the above points. Under the same size and type, A1AA pearls are the best and of course the most expensive. |
