silver earrings manufacturers Remember one sentence, you can identify true and false pearls

Postado em por Kingjy

There are four criteria for evaluating the quality of pearls: shape, tamanho, luster and color. The shape of the pearl is of course the rounder the better; the larger the size, Quanto melhor. When the pearl weighs more than ten carats (mais do que 2 grams) and is round again, it is a rare treasure! The surface of the pearl has a rainbow-like luster. The brighter the luster, the more prominent the color, Quanto melhor; the color of the pearl is mainly white, sometimes with pale pink, amarelo, blue-violet, laranja, brown and other colors, as well as a special band Blue and black, from the price point of view, black pearls with blue and metallic luster are the most expensive, followed by pleasing silver-white and various bright colors.

Hoje em dia, the output of cultured pearls is very large, especially the price of freshwater cultured pearl jewelry can be said to be very low. No entanto, pearls that are particularly round, large in size and good in luster are still extremely rare and very expensive. Portanto, there is still a market for imitation pearls with beautiful appearance.

The so-called imitation pearls are commonly known as “fake pearls.” Imitation pearls are made of plastic, glass, ceramics, thick shells, etc.. into small spheres, or shell powder is bonded and pressed into small spheres. Then prepare a special “pearl semen”, soak the above-mentioned small ball in the liquid, and soak it for many times. After drying, the surface of the small ball will produce a pearl-like luster, which becomes an imitation pearl. The craftsmanship of imitation pearls is very different, the false appearance of low level is exposed, but the appearance of high craftsmanship is very much like high-quality seawater pearls, which makes it difficult to distinguish the authenticity. Since there are still imitation pearls in the market, people always worry about whether the jewelry they buy is real pearls when they buy pearl jewelry.

Na verdade, it is extremely easy to distinguish real pearls from fake pearls. Just remember one sentence, which is: “Any faulty pearl is real.” The faults of pearls include: the shape of the pearl is not round, long or flat like a pumpkin, or irregular, and the shape of each grain is not exactly the same; the surface of the pearl has small pits, small protrusions, large and small lines Wait. A string of ordinary pearl necklaces, every pearl must be faulty, and no two pearls have the same fault. Even a string of high-end pearl necklaces worth tens of thousands or even hundreds of thousands of yuan, a closer look, almost every pearl has a small problem, but it is not obvious.

Only the fake pearls produced by the machine are round, smooth and bright, and there is no problem. To be a joke, if the fake pearls produced by the machine want to create different small defects on each one, the cost is too high, and it will be much more expensive than real pearls, so no one buys them.

If it is a pearl ring, there is a pearl on it. This pearl is round and smooth, and there is nothing wrong with it. How can it be verified? You can place it on your teeth and scrape it lightly. The real pearl has a sandy feel, while the fake pearl has a slippery feel like touching a glass ball. If there are two pearls, you can gently rub them together. The real pearl has a sandy feel while the fake pearl For slippery.

Pearl is squeamish, pay attention to maintenance. The hardness of pearls is lower than that of iron and glass, and they are easily scratched. The chemical composition of pearls is mainly calcium carbonate, which is the same as the building material marble. It is easily soluble in acid, and even vinegar can corrode it. Pearls are not suitable for contact with grease, cosmetics, salt, sauce, colored pigments and human sweat, because these things will deteriorate the luster of the pearl or stain it. Portanto, after the pearl is worn personally, especially in summer, it should be washed with water and dried every day.
