1. Texture. Red corals have longitudinal stripes in parallel and coral growth, and are tightly discharged. In addition, the cross section of the red coral has a ring -like ring like a tree wheel. When looking at the red coral identification, pay attention to these two textures. 2, look at the color. Red coral color is a vivid and vivid red. Whether it is shallow or deep, it is alive, not dead, not stagnant! And the red coral has a bright waxy luster, and the dyed red coral has no gloss, the color is stagnant and dead. Sink. 3, listen to the sound. Coral seems delicate but has a crisp and tough sound when colliding with each other. Generally plastic or other imitation corals will not have this hard and crisp sound. This sound is particularly obvious on branched corals! The red coral also has some natural flaws, such as pressure patterns, black spots, white spots, sandylons, insect eyes, etc., although they are coral flaws, but they are also one of the important signs of red coral identification.

The following methods of identifying the authenticity of red corals are relatively simple: 1. Look at texture, red coral is growth. In the deep sea, there will be stress patterns, and there are concentric lines in the cross -section; and many fake red coral patterns are radioactive texture, which is obviously different from natural red coral patterns. From the perspective of the vertical surface, the natural red coral is water -like or vortex -shaped, and the fake red coral vertically presents the parallel texture.n2. Looking at the color of the red coral, the color of the fake red coral is rigid and dull, and it will expose some white core, white dot and its own red boundaries.

Hello The pure coral jewelry has the following characteristics: 1. There are natural fine oblique and horizontal texture, and each piece of coral is different. 2. There are natural flaws, such as small white dots, small black spots, and small spots, not bad products. 3. It is the only thousand -year spiritual material in jewelry. It is glorious, gentle and pleasant, crystal clear, and charming. 4. Wearing itself to promote blood circulation, and changes in various colors according to the physical condition of each person, so it can be called an observation station for human body, qi, and God. 5. Coral jewelry has functions such as beauty and health care, blood circulation and eyesight, and it is also a symbol of auspicious preciousness. S several kinds of counterfeit coral products: 1. Use coral jewelry made of sea willow and sea bamboo. 2. Fill in coral staining 3. Synthetic coral staining 4. Various types of jade imitation coral products 5, plastic dyeing coral 6. The easiest to use fake and true coral is called "beauty coral". The powder is wrapped layer by layer, and the natural defects of red corals such as small white dots and small black dots are imitated into the most valuable dark red corals and peach corals, and sometimes they can achieve falsehood. In three points to buy corals. One must be uniform in color, and the other must be red and red, the more precious, the more precious, the third is larger, the heavier the better. The appearance of coral is completely different from that of how much color -like Bedtar. The luster of the beads has a certain direction. When it is magnified at a low double, it shows an extremely flame. The white rosary with fake white corals with shell shells can be identified through the parallel growth structure on the shell and its pink band trends. The other identification of corals is a small and shallow round concave pit, which is the growth site of individual corals. Small concave pits caused by some perforated marine creatures can also exist. The main substitutes of imitation corals are cellulu, wood and wax, none of them have the unique appearance of corals. When cellulite is heated, the camphor smell is produced. The wood can be scratched with fingernails, exposing the wooden structure under the artificial surface, and the sealing wax looks like a glass -like appearance under the magnifying glass. If necessary, you can use hydrochloric acid to identify these prolazes, because none of them will work with hydrochloric acid. Conversely, corals, shell pearls and shell shells react with hydrochloric acid. Due to the small output of red corals and high value, people often use low -cost white corals to be red like red corals. To identify the above fake red corals, you can use a cotton swab dipped in acetone. Because the color of the artificial dyed is dull and rigid, the surface is different, and the dye can be seen in the small cracks of the coral with 10 times the large mirror. The identification of dyeing coral depends on its dyeing level. Those who are dyed are not soft and natural, excessively glamorous, red without layers, and really red corals are candles red, red have layers, some are still red and white, and "fingerprints" are faintly revealed in the middle.

If there is no license issued by the state, it is not allowed to be sold, so 99%of the businesses without permits sell them. You have to distinguish it carefully and beware of being fooled. The inside of the coral branches is not solid. Is to answer can help you
There are very few red corals, mostly fakes. Differential method: The drops of hydrochloric acid will produce bubbles. It is a real coral, grind it. If the color inside and outside is the same, the white inside is white. Looking at the magnifying glass of more than 20 times, you can see that the hexagonal tissue is true coral.

Per other identification features of corals are small and shallow round concave pits, which are the growth parts of individual corals. Small concave pits caused by some perforated marine creatures can also exist. The main substituts that imitate corals are cellular, wood and wax, none of them have a unique appearance of coral. When cellulite is heated, the camphor smell is produced. The wood can be scratched with fingernails, exposing the wooden structure under the artificial surface, and the sealing wax looks like a glass -like appearance under the magnifying glass. If necessary, you can use hydrochloric acid to identify these prolazes, because none of them will work with hydrochloric acid. Conversely, corals, shell pearls and shell shells react with hydrochloric acid. The value of red coral production is high, so people often use low -cost white corals to be dyed red to rush to call natural red corals. To identify the above fake red corals, you can use a cotton swab dipped in acetone. Because the color of the fake dyed dyed is monotonous and rigid, the surface is different. The dye can be seen in the small cracks of the coral with 10 times the large mirror. Essence The identifying dye coral depends on its dyeing level.

Pura phenomena of several counterfeit and inferior coral products: 1. Use coral jewelry made of sea willow and sea bamboo. Phenomenon: It has obvious longitudinal texture and uniform color, giving people a sense of dazzling, without the characteristics of coral jade unique pores; 2. Fill coral staining: It is a loose texture of shallow sea branches -shaped reef coral for coral coral Fill in the glue method to fill the dyeing. Procedure: shallow sea reef-injection filling-appearance dyeing ---- polished-made into various coral products; phenomena: smooth surface, rough and fragile, and easy to fade in color; 3. Synthetic coral staining : It is a variety of shellfish or reef corals to grind into powder, and plastic into various coral shapes. Phenomenon: There is no natural texture, almost every coral is the same, and the color is easy to fade. 4. Various types of jade imitation coral products: dyed with white clouds or squares; The phenomenon: The color is very uniform, but it is easy to fade, and there is no gloss. 5. Plastic dyeing coral: dyeing with plastic products into corals; phenomenon: light texture, easy fading, no natural texture and luster.
