custom jewelry ring box wholesale Coral variety, evaluation and purchase

wholesale jewelry personalized plaque The English name of coral is CORAL, from Latin. Coral is one of the important organic gems, and it is also a favorite gem variety of ancient and modern China and abroad. The ancient Romans believe that corals have the functions of preventing disasters, giving wisdom, hemostasis, and heating fever. It has a close relationship with Buddhism. Buddhists in India and Tibetan China regard red corals as the incarnation of Rulai Buddha. They use corals as mascots of Buddha sacrifice, mostly for Buddha beads, or decorative statues. Gem variety.
coral is a kind of sea -ranging cylindrical cavity, named "Coral". During the white larvae stage, it is automatically fixed on the lime relics of the ancestors of the ancestors. Corals rely on their own tentacles to capture food, and secrete a kind of lime (mineral composition is Fangli Stone) to build their own body. In the process of growth, in order to capture food and absorb sunlight more, in addition to growing up, it also expands forward, left and right to form biological groups like branches -like biological groups in three degrees. Take out a beam of grace, beautiful and moving, it is a natural artwork.
The chemical composition of corals is mainly CACO3, which exists in the form of microcrystalline squares, and there are a certain amount of organic matter in the ingredients. The shape is mostly branched, with vertical stripes on it. Each monolithic coral horizontal surface has concentric and radial stripes. The color is often white, and there are a small amount of blue and black. Gem -level corals are red, pink, orange -red. Red is formed by absorbing about 1 % of iron oxide in the seawater during the growth process. Black is due to organic matter. It has glass luster to wax -like luster, opaque to translucent, and the discount rate is 1.48-1.66. Hardness 3.5-4, density 2.6-2.7g/cm3, black coral density is low, 1.34g/cm3. Crispy. In the case of hydrochloric acid, it is strongly foam. No fluorescent.
coral variety, evaluation and purchase. The varieties of corals include red coral (known as "bull blood", "angel noodles"), black corals, blue corals, Mediterranean corals, Japanese corals, Cameroon corals, Hainan corals in China. The quality of corals is almost the same, and color and block are the basis for economic evaluation and purchase. The color is higher than the white quality, and the color requires beautiful, bright and pure. The larger the block, the better. The value of corals is also influenced by various local customs. For example, the Arabs prefer bright red, while European pink is popular.
Ifging of coral and identification. (1) Driving Dali: It is uniform red, with a granular structure, and the horizontal section has no same -hearted structure. There are not uniform stripes. Wipe with cotton swab dipped in acetone, and red on the cotton swab. (2) Pink glass: glass luster, containing air bubbles, shell -shaped fractures, and not foaming in hydrochloric acid. (3) Pink plastic: There is no strip -shaped structure unique to corals, with traces left by the use of molds. (4) "Gilson" synthetic coral: Fine fine -grained structures, the strip -shaped structure with a slightly different color or transparency of natural corals cannot be seen. The density is 2.45g/cm3, which is smaller than natural corals.
The corals with good shapes often make ornamental stones, and can also be used as raw materials or processing of sculpting art or processing necklaces, rings, bracelets, brooches, earrings, etc. Coral can be used for medicinal medicine.
Prepass protection. Because the chemical components of corals are CACO3, the chemical properties are unstable. When the human body sweats in summer, it is not advisable to wear coral necklaces for a long time. Because of the salt and acid secretions in sweat, the coral will be corroded. Corals should not contact cosmetics, perfumes, alcohol, salt, oil and vinegar, etc. The structure of the coral is not dense, with pores, and it is easy to sog. Use neutral soapy water during washing.
Corals are produced in warm ocean areas. The reef corals grow in a relatively shallow warm sea in the near shore, usually the most vigorous growth of 30 meters from the water surface. The Mediterranean is the famous place for coral gemstones. The Red Sea in Africa is known for many coral reefs. In addition, there are good quality corals from Spain, the Japanese Ogasawara Islands to the Sulfur Islands, Taiwan Keelung and Penghu Islands.
The authenticity of coral jewelry
The natural coral jewelry has the following features:
The natural fine oblique and horizontal texture, each piece of coral is different.
The natural flaws, such as small white dots, small black spots, and small spots, are not bad.
is the only thousand -year spiritual material in jewelry. It is glorious, gentle and pleasant, crystal clear, and charming.
It -wearing 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.
coral jewelry has functions such as beauty and health care, blood circulation and eyesight, and it is also a symbol of auspicious and rich.
Pura phenomenon of counterfeit and shoddy coral products:
. Coral jewelry made of sea willow and sea bamboo.
The phenomenon: There are obvious longitudinal textures and uniform colors, giving people a sense of dazzling, without coral jade unique pores.
. Filling coral dyeing — It is a loose light sea branches -shaped reef coral filled with staining.
Programming: shallow sea reef coral — glue filling -appearance dyeing — polishing — making various coral products.
The phenomenon: smooth, rough and fragile, and the color is easy to fade.
. Synthetic coral dyeing — It is a variety of shellfish or reef corals to grind into powder, and plastic into various coral shapes.
The phenomenon: There is no natural texture, almost every piece of coral is the same, and the colors are easy to change the legs.
. 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 has no gloss.
5. Plastic dyeing corals — dyeing with plastic products into corals.
The phenomenon: light texture, easy fading, natural texture and luster.
6. The easiest to use false corals to be called beauty coral is the core with inferior coral or white coral, wrapped with special coats and coral powder layers, and the red corals are defective such as small white spots and small black spots one by one. Imitation has become the most valuable dark red coral and peach coral. Sometimes it can reach the true level of falseness. Generally, it is difficult for consumers to distinguish.
The red coral: The strangeness in the jewelry Baihua Garden
This of red coral, the strangeness in the jewelry Baihua Garden, greatly enriched and beautified people's lives. More and more people like it. It can be said that she has really entered people's hearts and has entered millions of households. Red coral is very magical, very mysterious, and has a lot of beautiful legends. In order to explore the secrets of red corals, the author recently visited Zhao Guangzan, a senior adviser to the famous red coral experts in my country, senior consultant of Beijing Firen Red Coral Jewelry Company, and a professor at the Jewelry College of Beijing University for Nationalities. Essence
It: I heard that coral is a aquatic animal, so how does it evolve into gems?
Professor Zhao: Red coral is an important member of the jewelry family. It is called the three major organic gems with amber and pearls.
coral is a aquatic animal, which belongs to the cavity animal door. The ancestors appeared in the ancient times after the Earth was formed.
This for the formation of the earth has been 4.6 billion years old. Geologists call the long period of 570 million years ago as the hidden lives; 570 million years later, it is called Xiansheng. The Xianshengzhou was divided into the Period, during the middle of the middle, and the new generation. The so -called ancient generation was a historical period between the earth from 570 million to 250 million years. During this time, a large number of life activities appeared on the earth. The ancestors of corals were a aquatic animal that appeared and a large number of breeding and development during this period.
The corals that reproduce and develop a large number of corals during the ancient generations.所谓四射珊瑚就是它圆筒形状的腔体中有四个床板，并由床板分隔成四个腔房，每个腔房有一个触手，即四个触手，触手就是它的吸盘，也就是珊瑚The mouth, corals rely on the food in the sea.
Geological periods have evolved to a geological period from about 250 million to 65 million years. The earth is called the middle generation. During this period, six shot corals appeared on the earth. Earth evolved into the new generation to modern times after 65 million years, including the third and fourth disciplines. In about 2 million years, ancient human activities (ancestors of human beings) appeared, and the Beijing Ape -Man activity of Zhoukou stores appeared around 400,000 to 500,000 years.
The earth has evolved into the fourth period of geological period, that is, in modern times, there is an eight -shot coral, that is, there are eight bedboards in the coral cavity, and the bedboard is divided into eight cavities. Each cavity room is also the same. Developed tentacles. That is eight tentacles.
The corals have evolved from the four -shot corals of the four tentacles of the ancient generations to the six -shot corals of six tentacles in the middle generation to the eight -shot coral of the eight tentacles of the new generation. The result of evolution. Today's red coral is an eight -shot coral with eight tentacles.
This: The original coral ancestors were about 500 million years earlier than human ancestors. So how does it change from animal coral to coral stones?
Professor Zhao: Corals are formed by the deposition of bones of low -class intestinal animal corals. Countless small coral worms were originally distant relatives of jellyfish. They could swim freely in the water when they were not adults. When it started to start on the legacy of the ancestors, its tentacles shrink into the body during the day, and it extends out at night to capture floating! Biological hunger. Its body is round tube, with two layers of cells and one layer of glue, and the in vitro is wrapped in lime and keratin secreted by itself. Coral insects rely on asexual reproduction -division and proliferation methods to breed rapidly. People have long mistakenly thought that corals are plants. It wasn't until the 1920s that people discovered that it was an sea animal. The corals that the group live in constant reproduction and death. After the death, the coral calcification of the coral becomes a stone carbonate ingredients to form various strange and strange uses of coral stones, and it also creates a gorgeous and natural -shaped crafts.
Is: What are the types of corals?
The Professor Zhao: There are many types of corals. According to the principles of biology, there are about 36,000 corals in the world.
Che people according to the economic value of corals according to the needs of corals, people are divided into two categories: banned shallow sea environmentally friendly corals (also known as reef corals) and valuable deep -sea treasure corals.
Is: Why are corals that grow in the shallow sea and are called "environmentally friendly corals" and forbidden
Professor Zhao: The environmental protection corals of shallow sea are widely distributed, accounting for about 98%of the entire coral family. There are environmentally friendly corals in the Pacific, Atlantic, Indian Ocean, and subtropical waters. They generally grow in the water depth of about 0 to 50 meters, and the temperature is cleaned in near -shore waters at 20-30 degrees.
The speed of reef corals in shallow sea growing and metabolism in a suitable environment is very fast. After the death of animal corals, their skeletons accumulated into reefs, and they were called reefs that were not exposed.
The coral reef platform is distributed in the waters of the east coast of Hainan Island in my country. In the waters of the northeast coast of Australia, there is a world -renowned Great Barrier Reef. The Penghu waters of the Taiwan Strait of my country are also distributed with more shallow sea reef coral reefs.
The platform caused by coral reefs is regarded as protector of the land area ecology. Due to the existence of coral reefs, it can greatly reduce the invasion of sea breeze, waves, storms, tsunamis, typhoons, etc. The role of protecting the ecological environment.
Ilads to calcium carbonate because the chemical composition of coral reefs is often used by locals to minimize and refine lime. Excessive mining reefs often cause the back coastline. The backward of the coastline means the decrease in landing area. Over the years, it means that the island disappears. In order to stop such incidents that damage the ecology and the human survival environment, the international environmental protection organization issued a notice in recent years, and governments of various countries have also issued notifications to prohibit and prohibit the shallow coral coral.
If: Deep sea corals are called "treasures". What special value does it have?
Professor Zhao: The corals of the deep sea grow in a waters of 200 meters to 1,000 meters underwater. It is very limited in the world, accounting for only 1-2%of the coral family. It is the main raw material for carving art and jewelry. Therefore, it is very valuable and very rare.
Madon coral after the death of the deep -sea corals turned into coral stones through calcification. Because this process is completed in the deep sea. The pressure of water in the deep sea is large, and the coral stone mineral composition caused by calcification is Fang Lingshi. The holes of coral stones are small, less, and the surface structure is harder. The proportion is usually 2.5-3.0 and the hardness is about 3.5-4.0. Its growth texture and growth festival are not obvious.
The main body in the deep sea coral is the red coral family. Red corals are branches, each branch is a single, and a coral tree is a coral group made of multiple monomers.
The growth festival and growth texture of red corals are like the annual wheel of trees. In addition to showing its growth age, it also shows the nutritional status of the growth process. The development of the growth festival is about 0.5-2.0 cm. The distance of the growth festival depends on the overall development of corals. There is a good growth texture between the growth and growth festivals, and the development of the growth texture is disorderly, which is an important feature of it. According to the growth festival, it takes about 1,000 years of animal coral to grow 1 meter -high. The 1 meter -high coral tree is completely calcified to coral stones, which takes about 10,000 years. The so -called thousands of corals are all overwhelmed.
This: Many people think that the color of red coral is red. In fact, this red is naturally formed. So how do you form?
Professor Zhao: The color of red coral is a question that people generally care about. The reason why red corals are valuable is that its color is pure and natural.
It in the deep sea waters distributed by red corals, a large number of volcanic activities have developed. These activities provide a lot of volcanic ash substances. The volcanic ash material contains a certain amount of constant elements (such as iron, manganese, etc. Colorless elements magnesium, potassium, sodium, etc.) and trace elements (such as zinc, chromium, nickel, etc.). After the death of corals, it becomes a coral stone. This calcification process is the process of being replaced by calcium carbonate. It is the adsorption of various elements in the seawater during calcification. If the adsorbent elements are mainly iron, the color of the coral stone is red. The color of coral stones will be pink or pink. If the adsorbed elements are mainly magnesium, there are almost no other impurities, so the color of the coral stone may be white. Pure white corals in the deep sea are even more rare treasures.
It: As far as I know, the deep sea red corals in Taiwan are famous, so is there still deep sea red coral in other seas?
Professor Zhao: Taiwan is rich in red coral. The output of the heyday accounts for 80%of the world's output. Therefore, Taiwan is known as the "coral kingdom".
The distribution of red corals in the world mainly has three major regions:
(1) The Mediterranean coast is mainly based on the waters of the southern Italian Peninsula. Sea around the Hawaiian Islands;
(3) Taiwan's waters, southern Japan, including the Ryukyu Islands. In addition, there are sporadic distributions of deep sea red corals in the waters of Guam and Midway.
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.
It about whether there is a deep water growth environment.
The tropical waters in our country are mostly flat ramps in the mainland, which has created the smaller slope of the bottom of the sea and the slope extends extremely smoothly. It can be said that there are basically no growth conditions for deep water corals. The various white honeycomb -shaped corals and branches of red coral we see in Hainan Island and its surrounding waters are all under the conditions of light sea conditions.
The waters that are rich in corals in the four weeks of Taiwan Island, including Suao Water, Penghu waters, south of Hualien, and South China Sea waters, but the output of valuable corals is mainly based on the waters of eastern Taiwan. The South Water Area is an important region of the deep sea red coral. The coast of the eastern part of Taiwan is relatively steep, which provides conditions for the growth and development of red corals in the deep sea.
This: People say that coral has the effect of beauty and beauty and health care. How can it have this magical effect? What do you think of this problem?
Professor Zhao: Red corals are not only jewelry with ornamental value and value preservation value, but also have beauty and health care value. They are known as healthy jewelry.
The characteristics of water absorption brought by coral with this porous structure, many wearing women of red corals will be surprised to find out: the color of the red coral beads on sunny and cloudy on the cloudy day, the red coral in the rain and dry season The color of the color is different. The color of wearing corals in the north is not the same. When the body is unwell, the coral beads are different when they are healthy and healthy.
The development of modern medicine confirms that coral stone is not only a real baby, but also has a lot of medicinal and medical value. Medical master Li Shizhen told people 400 years ago that corals have medicinal value such as bright eyes, removing blood, and nosebleeds. Corals can also be used to stop back pain, clear heat and detoxify, sweat and diuretic, can be used to get bone, can cure arteriosclerosis, hypertension, coronary heart disease, etc. The whole body of coral stone is treasure, which is comparable to any gem that cannot be compared with it. Large pieces of upper coral stone materials can be carved into jewelry art of various valuables. Small pieces can be cut into rings and necklaces. Those corners can be grinded into powder to make beauty health products. So it is a veritable modern fairy Dan, a veritable health jewelry.
It: There are many beautiful legends about red coral, can you introduce it?
Professor Zhao: Human use of corals can be traced back to the ancient Roman era. The Romans called it "red gold". At that time, people thought that coral could protect themselves, dispel evil spirits, and had functions such as promoting blood circulation, eyesight, and fever. For fishermen, the waves can also be flat, predicting the danger of lightning and typhoons. Legend of corals has always been covered with mysterious colors. Red corals are the rare of the world, but only in China pushed red coral culture to the extreme, and in various historical periods in my country, there are many wonderful legends. (Junshi)
three factors affecting the value of coral
Curaced coral, pearl and amber are tied as the three major organic gems in the West. Due to the increasingly serious marine pollution and the difficulty of collecting in the deep sea, the acquisition of valuable corals obtained The amount is less and less, and it shows its rarity and preciousness. There are many kinds of corals, what kind of corals have the collection value? Here is how to choose.
The color is better than color
coral types can be divided into white coral, light powder or dark coral, peach coral, and you can see black corals (that is, sea trees) in Hawaii. Among them, red coral, blue coral and black coral are the most precious. Taking red coral as an example, there is a saying called "Millennium Coral Wannian Red". Red coral is worthy of its growth, long life, strong quality, colorful, and scarce production. Red corals are sorted in color according to the advantages and disadvantages:
The best:
The dark red coral (Aka Red): The often referred to as Aka dark red.
This red coral (Momo Red): Usually meat red, rose red, orange red or salmon red.
The pink coral (Angle Skin): The face of the angel that is often said, the branches are dense and the vertical lines similar to fingerprints.
MID WAY: The color is relatively uneven and mixed with a little dark red dot.
The larger the more pieces, the better the corals, the more the coral is, the more the coral growth is long, or the root of the coral, the thicker it is more precious. The most important thing for coral processing is the body tailoring, and corals of different sizes and different colors often have different uses and processing methods. First of all, large, a certain shape of coral is often saved by the whole pruning to design large crafts or furnishings. The small coral branches with a small degree of block are processed into jewelry or accessories. Among all coral varieties, it is the highest value for carving coral decorations.
delicate and smooth
The surface is smooth, the feel is smooth, full of shiny luster. The surface of the coral body has no stains and uneven scars on the surface of the coral. This is the superior choice.
The obtained amount of red corals in the world today is between 100 tons and 400 tons. The price is mostly several times or even dozens of times of gold. In many auctions, the price of red coral works is also amazing. When making corals into exquisite jewelry or carving into famous artworks, its value is doubled.
Coral: Record the clock of geological history
It in the beautiful South China Sea, a group of reef islands like jade beads are distributed. But do you know how these reef islands are formed? It turned out that they turned out to be caused by many tiny and primitive marine life in the long -term geological history. The marine creatures that created these reef islands were corals.
On beautiful corals
coral is one of the important organic gems, and it is also a favorite gem variety that is well -loved by ancient and modern Chinese and foreign. The ancient Romans believe that corals have the functions of preventing disasters, giving wisdom, hemostasis, and heating fever. It has a close relationship with Buddhism. Buddhists in India and Tibetan, Chinese, regard red corals as the incarnation of Rulai Buddha. As the mascot of the Buddha, it is a cherished jewelry gemstone variety.

The shape is mostly branched, with vertical stripes on it. Each monolithic coral horizontal surface has concentric and radial stripes. The color is often white, and there are a small amount of blue and black. Gem -level corals are red, pink, orange -red. Red is formed by absorbing about 1 % of iron oxide in the seawater during the growth process. Black is due to organic matter.
The ancient animals of the era
have always thought that coral is a plant. Indeed, they look like plants, or static or swaying in the water flow. But in fact, they are animals. Coral is fundamentally a jellyfish, a jellyfish no longer drifting in the ocean.
The primitive vertebrates living in the ocean, corals include modern anemia, stone corals, red corals, and extinct four -shot corals, horizontal corals, and so on. The entire coral family forms a outline in the intestinal animal door, called coral outline, which is divided into 4 sub -outlines, four -shot coral subclase, six -shot coral subclase, and eight -shot coral subclase. Among them, horizontal corals are the oldest, and most of them live in the late Cambrian period to triple chronicle. Only a small group called thorns is continued to the third year. It is only distributed from the middle of the Okota to the Permian; while the six -shot coral and the eight -shot coral have been survived from the emergence of the Triple Period to modern times. However, some scientists believe that the emergence of eight -shot corals can be traced back to the mud basin and even the end of the Cambrian.
This clocks of the history of geological history
It scientists believe that the growth law of the growth line on the surface of the outer wall of the coral is related to seasonal temperature changes and periodic changes in nutrient supply. The concept of time is linked. The growth line of modern corals is a circle every day and night, and the growth line every 28 circles constitutes a growth zone, which is equivalent to a cycle of a lunar month (28 days). By observing and calculating the growth lines of the four -shot coral fossils in each geological period, paleontologists calculated the basis number of time consistent with the calculation of astronomical methods. The four -shot corals of the Pen Penji have a growth line of about 400 laps each year, and the charcoal period is 385 to 390 laps. This indicates that the number of days from ancient to this year in the geological period is gradually decreased, but the number of days is in the day of the day, but the number of days is on the day. gradually increase. This result proves that the speed of Earth rotation is slowing down! Small corals can still be used as a clock in the process of recording geological history!
The basic common sense of corals
Corals are divided into two types: calcium coral and keratinic coral.
Calcium type: It is mainly composed of calcium carbonate, containing very little organic matter, including three varieties
1. Red coral: red to orange -red with light to dark tone, sometimes flesh red. Mainly distributed in the Pacific Sea.
2. White corals: distributed in the South China Sea, the Philippine Sea, and Ryukyu waters, etc., which are white, gray, milky white, porcelain white corals. Mainly used for bonsai crafts
3. Blue coral: blue, light blue coral.
Horn corals: The main ingredients are organic matter, including two varieties
1. Black corals: gray -black to black corals, almost all composed of keratin, high value.
2. Gold coral: golden yellow, yellow -brown keratin coral. The appearance of golden coral has clear spots.
