Actually The identification of coral is very simple:
1: Various view: Coral has a parallel growth pattern vertically, and the direction is parallel coral pillar. If it is a ring, it is usually on the back.
2: Look at it: There are growth patterns like the annual wheel on the cross section of the coral, which is small and large. There are concentric circular growth patterns, which are generally visible on coral ornaments.
3: See color: The color of the coral is from the inside out. For example: a coral column, the closer to the surface, the darker the coral color, the more the inner layer, the lighter the color. In other words, the color of corals is uneven. If the coral color is consistent inside and outside, it is necessary to suspect that there is a fake!

The development of modern medicine confirms that coral stone is not only a real gem, but it also has many medicines. Use and medical value.
coral is one of the earliest gems to be recognized and used by people. Some people think that corals were discovered by the Indians in the fifth century BC, and some people thought it was first discovered by the Italians before 2000. In the Mediterranean Italian coral fishing ground, the oldest history of mining has been mining in 2000. So far, Italy has also been popular with corals to avoid evil amulets.
It, in addition to the treasures of life as a life in the jewelry world, it is also considered a medicine treasure with unique effects. There are many medical effects such as perspiration and diuresis. More than 400 years ago, Mr. Li Shizhen, a master of medicine, recorded the coral in the classic masterpiece "Compendium of Materia Medica": "Go to the eyes of the eyes, solemn the town of the gods. It is used for the obstacles, epilepsy, and nasal towels." According to relevant information, coral stones have the effects of relieving vomiting, stopping diarrhea, stopping hemostasis, cure of low back pain, pediatric shocking wind, clearing heat and detoxifying, removing phlegm, cough, and diuretic diuretic. The latest foreign studies believe that corals can be used to get bone, and medicine can cure ulcers, arteriosclerosis, hypertension, coronary heart disease, and sexually transmitted diseases.
With the development of modern medicine, people have gradually discovered that red corals also have special functions that promote the metabolism of the human body and regulate endocrine. Therefore, some people call it "green jewelry" with pearls. It can be seen that in ancient and modern Chinese and foreign, whether it is an ancient ancestor or today, whether it is the court official or the civilians, they have sincere and pious beliefs and strong and unique preferences for red corals. Lile a rich humanistic foundation. The composition of coral stones is mainly calcium carbonate. After treatment, it can turn it into calcium phosphate similar to human bones. Therefore, the doctor uses it to repair the human bone. Wonderful is that human neonatal blood vessels can grow in the pores of coral stones with bone -making cells, so that the fracture part quickly returns to normal.
Americans bake coral stones through further research, convert them into bone mines, and add glass fiber to enhance polymers to increase intensity, so that it can not only be used for bone, but also It can be used directly instead of small or small bones, and it can also be used to "fuse" the spine, and even make a fake eye that rotates freely.
Speaking of the wonderful coral stone, more than that!
The whole body of coral stones is treasure, which is not compared with it.
The high -quality coral stone materials can be carved into a variety of valuable jewelry artworks. Small coral stone materials can be cut into ring, pendant, earrings, necklace, and so on. Those corners can be grinded into powder and made into beauty health products.
1. Red Coral: It is an organic gem, with a gratifying color and a clear texture. It grows in the deep sea from 100 to 2000 meters away from humans.
2. The price of red corals is different according to the size, color, style, and types of red coral. Followed. It mainly depends on quality and collection value. The focus is on dyeing sea bamboo, dyeing white coral, dyeing sea willow, dyeing marble, plastic and other counterfeiting methods.
3. In the final analysis, all jewelry exists to express a culture, but different jewelry has different cultures. Like jewelry without knowing culture is an empty jewelry. I like the story behind each jewelry. I often find the founder (red, palm. Cabinet) founder (red. Palm. Cabinet) to listen to the jewelry story.

Pay content for time limit to check for freenAnswer 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! Red corals also have some natural flaws, such as pressure patterns, black spots, white spots, trachoma, insect eyes, etc., of course, they are coral flaws, but they are also one of the important signs of red coral identification.nCoral individuals are gorgeous, and the colorful colors are not inferior to various flowers on the land. Some coral varieties and amazing fluorescent effects. Different types of corals can be built into a three -dimensional coral reef ecosystem in the aquarium, so that corals can be used in the aquarium in the aquarium There is great competitiveness in the industry. It can be tested with coral instruments and tested red coral data through scientific instruments, such as density, hardness, refractive index, etc. The density of red coral is 2.16 ~ 2.70g/cm3. The rate is 1.65, the density of black corals or gold coral is 1.30 ~ 1.50g/cm3, and the demolition rate is 1.56. As for imitations such as reef corals, the density and hardness are even lower. The identification of natural corals and imitation: The common "Gilson coral" made of coral imitation is dyed, red glass, red plastic, and square fossil powder. None of these imitations have natural Red Shan.
1 Type of coral:
coral can be divided into shallow coral and deep sea corals. The shallow corals are widely distributed, and there are many small islands made of coral reefs in the shallow waters of the Pacific, Indian Ocean, and Atlantic Ocean. The density of shallow coral is less than 2 and the hardness is less than 2. It cannot be used as a raw material for carving art, and can only be used as a strange stone for viewing.
The shallow sea corals are also called reef corals. The coral reef platform developed by it can greatly alleviate the destruction of natural disasters such as typhoons and storms. The shallow sea coral reefs are cut to protect the area of the land.
The deep sea corals, also known as valuable corals, generally grow in corals with a depth of 200 to 2000 meters. Its distribution in the world has certain limitations. Because its petrochemical process is completed in the deep sea, the pores of coral jade are small and the density is large (usually between 2.5 ~ 2.8), the structure is dense, and the hardness changes are between 3 ~ 4. The main raw materials of jewelry jewelry are called valuable corals. Because red corals are the most precious in deep sea corals, red corals have become synonymous with precious corals.
The red coral can be divided into five categories: dark red coral, peach coral, pink coral, white coral, white coral.
2 The distribution of deep sea red corals in the world:
1, Taiwan waters, southern Japan, including Ryukyu Islands; The waters of the Hawaii Islands and the Midway Sea;
3, the coast of the Mediterranean, mainly in the southern waters of the Italian Peninsula. What is very interesting is that the above three areas are high incidence areas of volcanic earthquake activities in the world, including volcanic activities on the bottom of the sea. The development of volcanic activities under the sea provides a large number of constant elements such as iron, manganese, and magnesium. This provides extremely important material conditions for the color of red corals.
3 The formation of coral colors
The color of red coral is a question of people's common concern. Many people think that red coral is dyed red, but it is not born. One of the reasons why red coral is expensive is that its color is pure natural. So, how is its color formed?
This, in the deep sea waters of red corals, a large number of volcanic activities have developed. These activities provide a lot of volcanic ash substances. Non -color elements iron, manganese, and colorless elements, magnesium, potassium, sodium, etc.), as well as trace elements (such as zinc, rhodium, chromium, nickel, etc.). After the death of corals, it becomes the process of being replaced by calcium carbonate. This process is called calcification. During the calcification process, coral adsorb various elements in the seawater. If the adsorbent elements are mainly iron, the color of the coral jade is red. The color of jade will be pink or pink. If the adsorption elements are mainly magnesium and almost no other impurities, the color of coral jade may be white. The pure white coral jade in the deep sea is also a rare treasure

Sometimes they can achieve the true level of falseness. distinguish.
The price for corals has no recognized system. Generally, it is divided into three levels according to the source of corals. The first is the living coral. This coral structure is dense and luster is the best raw material. The second is the coral that has stopped growing but still eroded by seawater. The third is the coral that is dead, that is, the bone residue after the death of the coral worm. This coral generally has a holes and a loose structure. Coral finished products can generally be classified according to color. The dark red corals are the most precious, followed by pink, while white and black are poor. In addition to seeing the color, the luster of coral polishing is bright and particle size is also a factor for valuation. Large grains, strong luster, and tight structures are high.
