Color characteristics: persimmon red, that is, vermilion, otherwise it is easy to mislead because persimmon has a long red sequence, which can be called many kinds, even including all reds such as light red to deep red and purple.
This species is usually produced in Gansu, Sichuan, Yunnan and other places, and its color is relatively light.
Texture characteristics: Visually, Nanhong has a rubber texture, and its light transmission is relatively weak, that is, it is transparent but not exposed. The light transmittance of large materials is much weaker visually, while the light transmittance of small materials, such as beads below 20MM, is relatively transparent.
Value recognition: in terms of color, we can see that the color is transparent from the inside out, preferably relatively uniform. This kind of finished product or raw material is extremely rare. At present, there are almost no successful cases of counterfeiting, unless the old materials and new workers pick up the fine products from the materials with bigger fists or smaller fists. Good quality, uniform color is extremely rare, and the price is extremely high.
False south red: the main feature is that the color is too uniform and perfect, and the material is usually flawless. More identification methods are not detailed here.
Old products: Weathered lines of old products, most old agates, especially old chalcedony, will have wind erosion spots, and some will show half-moon lines or irregular stripes. Because of long-term use, acidic substances secreted by human body and external direct corrosive substances will accelerate the surface weathering and corrosion.
Man-made old texture, after zooming in, you can see the unnatural traces of object carving, which requires experience.
This is Yunnan material, but people can't recognize its color.
New weathering patterns have appeared on dzi beads and other high-value old beads, but it can be clearly seen that they are not in conformity with the surface patina. Moreover, because the size of the machine is too uniform, the shape is regular and rigid, and the old weathered patterns are usually shiny. For the time being, there are no weathering lines in mass-produced dyed Nanhong, and most of them are cracks on the surface of agate when it is directly fired at high temperature, including corrosion in some way. In short, unnatural. If you zoom in carefully, you will recognize it. Not mysterious.
Finished product modeling and patina: In modeling, the red material in the south is smaller, and the volume of uniform color is smaller, so the larger one will all be used as ornaments, and the smaller one will be used as beads or pendants. In addition to pendants, there are olive-shaped beads, round beads, drum-shaped beads, barrel-shaped beads, wheel beads, abacus beads, melon beads, spacer rings and drop-shaped beads (pendants), most of which are round beads, and there are also various sculptures made by blocks.
Perforation in the hole of South Red Pearl and its performance: The perforation of South Red Agate is very characteristic, and it may be that the pearl comes out after the two sides of aniseed are perforated. Before the Qing dynasty, the holes were generally relatively large, but later the drilling tools were improved, and some holes became smaller. Because of high hardness and slow drilling and grinding, the spiral in the hole is not obvious and there will be no white powder. After long-term use, the hole will be smoother due to wear.
At present, the raw materials of south red agate are scarce, and high-quality south red is rare, and there are not many old products and relatively inferior ones.

The name and origin of "Nanhong"
Donghong refers to the red agate obtained by burning red to add color to agate.
West red agate refers to the red agate that naturally appears red without any artificial coloring.
Just because the red agate mined in Baoshan area of Yunnan in the past 30 years is called Yunnan red agate, referred to as Nanhong, it is now commonly known as Nanhong agate.
Question 2: How to identify the authenticity of South Red Agate? Color characteristics of south red agate: persimmon red, that is, vermilion, otherwise it is misleading to understand persimmon, because persimmon red has a long order, which can be called many kinds, even including all reds such as light red to deep red and purple. This kind is usually produced in Gansu, Sichuan, Yunnan and other places, and its light color and texture characteristics are: visually, Nanhong is rubbery, with weak light transmission, that is, transparent but not exposed.

Question 3: How to identify the authenticity of Nanhong with naked eyes 1. characteristic
The key point of feature identification is to put the south red agate under strong light. Under the strong light, we can see that the red color of South Red Agate is the red color formed by countless cinnabar spots, which is not found in other agates. If the very red south red agate cannot be penetrated by light, this identification method is not applicable. With the development of geological exploration and the discovery of new veins, the south red agate in the market is mainly new mines in Baoshan, Yunnan and Liangshan, Sichuan. 2
Second, the texture.
South Red Agate is a unique variety in China, with delicate texture and scarce output. Generally, south red agate is made of rubber. Even if all the red, south and red beads are observed by light, the color can be seen from the inside out. Colorless south red beads will also have a hazy feeling when observed with the naked eye, as well as a glossy feeling similar to Hetian jade.

Third, color.
The common colors of south red agate are brocade red (including persimmon red), rose red, cinnabar red, red and white material, red material and cherry red, which are roughly defined as the color types of south red. These transparent or translucent colors, including almost transparent colorless, are roughly defined as the color range of Nanhong. Except persimmon red and scarlet, all colors are made up of tiny dots, which are very obvious under a magnifying glass. The number of white lines depends on the specific situation, such as ribbon and white red.
Fourth, knife scraping
Check the hardness of agate with a knife. Real agate is generally hard. Scratch with a knife will not leave scratches, but glass products will leave traces.

Verb (abbreviation for verb) transparency
Real agate is translucent or opaque, with some confusion in transparency, and some can see the natural waterline, but synthetic agate is generally transparent without layering.
Question 4: How does Nanhong tell the truth from the false? Hello, I hope my answer can help you! We can identify Nanhong from the following aspects: 1. The most common colors in Gansu are persimmon yellow, orange red, scarlet and pink. There is also an unusual purplish red. These colors are transparent or translucent, and some are close to transparent and colorless, which are roughly defined as the color range of Nanhong. And its white stripes depend on the situation, such as band texture and white and red half. 2, the texture of the texture of the south red is gelatinous. Even the red beads are not opaque. We can see that the colors are transparent and consistent from the inside out. On the other hand, even colorless beads have a hazy feeling. Note here that this texture cannot be faked for the time being unless the old material is new. So fake south red is basically pure red. 3. Look at the weathered beads. Most of the old pearls, especially the old chalcedony/Kate Ma pearls, have a half-moon weathering pattern. This pattern is mainly due to long-term use, and most of the patterns are cracks on the surface of agate when it is directly fired at high temperature. It is particularly important to note that the lines of Nanhong are very sharp, and all the lines will have obvious angles when turning, giving people a clean and neat feeling.
Question 5: How to distinguish the quality of Nanhong from the authenticity of 20 points?
Question 6: Excuse me: How to tell the authenticity of Nanhong? South red color identification method: South red agate. Common colors are persimmon yellow (orange red), scarlet and pink in Gansu. There is also the unusual purple-red. The transparent or translucent change color of these colors is almost transparent and colorless, which is roughly defined as the color scale of South Red. However, the texture of its white agate cup depends on the situation, ranging from band texture to white and red. Nanhong's lines here are very sharp, and all the lines will have obvious angles when turning, which (one of the important criteria for judging) gives people a clean feeling. (that is to say, red and white are distinct! Nanhong will not change except the white color line and the gradual change of red to transparency (sometimes accompanied by some associated minerals, black or turquoise). Texture: texture, Nanhong has a rubbery feeling. Even red beads are not opaque, so we can see that the colors are transparent and consistent from the inside out. On the contrary, even colorless beads have a hazy feeling. Note here that this texture cannot be faked for the time being, unless it is old and new. So fake South Red is basically pure red. Weathered lines: On the surface of beads, most old beads, especially old chalcedony/agate beads, will have half-moon weathered lines. This grain is mainly due to long-term use. The newly imitated beaten weathering lines have appeared on valuable old beads such as dzi beads, but it can be clearly seen that they are not consistent with the slurry made of flour and water fermentation, with the same size and hardness, and the lines are dark (shiny in the crescent, but shiny in the old weathering lines). The perforation of South Red Agate is very unique. It may be that the big material punched holes on both sides before beading (the holes will not be too small). It takes too long, and the wear in the hole is smooth. South red agate, the name itself is a mystery, and no one knows exactly when the name South Red originated.
Question 7: How to identify the authenticity of Nanhong? Please leave a message and thank you for the following fake South Red Agate in the market:
Dyed red agate, dyed quartzite, dyed gray agate.
The biggest feature of South Red Agate is that it can be observed with naked eyes, magnifying glasses and microscopes that the punctate chromogenic substances inside the agate, commonly known as vermilion spots. It is found that the main component of cinnabar spot is hematite. The picture below shows the appearance of cinnabar spots under the microscope.
In general, cinnabar spots can be seen by naked eyes and magnifying glasses, but the cinnabar spots with good texture of South Red Agate need to be observed under a microscope. Here, you need to look at the south red agate as a whole and cultivate your feelings for the south red agate.
Let's talk about the common fakes on the market:
1, red agate or dyed red agate. Dyeing and baking only changed the appearance of agate, but did not make agate have the characteristics of "cinnabar spots". A close observation of such fakes will reveal a feature: it is relatively permeable to water, but there is no cinnabar spots inside. Under normal circumstances, the cinnabar spots of permeable south red agate will be more obvious.
Zoom in and observe the picture below. The picture below shows the baked agate, and there are obvious banded fire lines on the epidermis. But there are no cinnabar particles.
Generally, in order not to let consumers clearly see the cinnabar spots, such things will be matte. But careful observation can still easily distinguish this fake.
2. Dye quartzite.
Dyed quartzite is made by crushing quartzite powder, dyeing and finally cementing and pressing. This kind of fake goods generally have a matte or semi-matte and waxy luster on the surface, and their main purpose is to deceive consumers who don't understand and make it inconvenient for consumers to observe the internal situation of the object. Dyed quartzite is generally translucent, and it can be found through strong light and light transmission that there are no vermilion spots and the color is filiform.
3, dyed gray agate. The agate dyed gray is confusing, much like the high-grade south red with full color and meat. But the difference is simpler. Dyed grey agate is usually punched after dyeing. In the process of drilling, due to the high temperature generated by drilling, the dye around the hole will fade due to the high temperature, and obvious translucent black circles will appear at the hole.
In addition, here, because Nanhong beads generally choose to punch holes in defective parts, sometimes one or two beads are punched in places with crystals, meat or impurities. We need to observe carefully here and treat fake black circles differently. Every bead of a fake has a small black circle, and every bead with defects is different.
Question 8: How to identify South Red Agate? Is there any good way? The difference between 65438+ and South Red Agate is very small, but it is a bit crucial. You can see uneven colors on his beads. In fact, this is very simple and invisible to the naked eye. You have to prepare a strong flashlight and it will come out as soon as it is illuminated.
2. See if there are cracks or lines in things. How can this be invisible to the naked eye? You have to use light or sunlight to help, but you'd better have a strong flashlight. Look at the structure inside, of course it is cherry red, so you can see it. If it is persimmon red or cherry red, it is better to use a flashlight to see if there are any cracks inside. In terms of value, there are generally flaws and minerals inside, as long as the outside does not affect the image.
3, look at the rules, generally can be seen by the naked eye, this is relatively simple, everyone will see! Of course, in terms of value, the more regular, the more valuable, and the more irregular, the less valuable! Of course, the most important thing in carving is to see the carver!
4, look at the water head, as long as friends who have contacted Nanhong know that some Nanhong looks very dry, dry means dry, good water head means good gloss, and it looks like water inside! This is also simple, as long as the first and second points are clear, this article will understand!
If you look at the sculpture here, the craftsman's craft is a key. The value of good craftsmanship is high, and the value of bad craftsmanship is greatly reduced!
6. If you buy Nanhong online, I don't recommend online shopping at the collection level. You'd better buy it yourself. You can't see Nanhong in the photo! Generally, when buying goods, buyers and friends must look at the pictures and buy them. I will be disappointed if I buy a good picture, and the price does not match, most of them are fakes or artificially processed!
7. Don't buy Nanhong for a penny. Nanhong is very popular now. Don't believe those deceptive lies. Now I have a psychology. The more you talk about losing money, the more you blow it, the more I suspect that your goods are fake. Who will lose money when the South Red Market is so hot? Refuse to lie!
8. For friends who have just come into contact with Nanhong, it is recommended not to buy it first. It would be nice to get it at an average price. In this case, you know something. There is another problem. If the price is low, you let him handle it manually or make a fake, and the labor cost is not enough.
9. For friends who have just come into contact with Nanhong, it is recommended not to buy it first. It would be nice to get it at an average price. In this case, you know something. There is another problem, if the price is low, you let him handle it manually or make a fake, and the labor cost is not enough!
Question 9: How to identify the authenticity of South Red Agate Generally speaking, there are three kinds of imitations of South Red Agate: ordinary agate, Warring States red and red glass.
South red agate: It has a gelatinous feeling. After magnification, we can see that there are red spherical inclusions, commonly known as "vermilion spots", with a refractive index of 1.54, with a characteristic reddish and rose color. Among them, Baoshan has many cracks, strong gel feeling, good transparency, good gloss in Liangshan, and poor light transmittance in fleshy Liangshan Nanhong.
Warring States Red: Compared with Nanhong, red is not bright enough, and it is opaque and has more colors.
Red agate: rare vermilion spots inside, no glue feeling, strong light transmission and dark color.
Red glass: there are bubbles in it after enlargement, and the red color is even and transparent.
Question 10: How to distinguish between true and false Nanhong and Bishi 50 points;
Color: Color is the most important feature of South Red Agate. How to identify fake south red agate by color is also a science. The common southern red colors are persimmon yellow (orange red), scarlet and pink in Gansu, and some unusual purples, as well as the transparent or translucent changes or almost transparent colorless of these colors, which can be roughly classified as southern red colors. Grain: Pay special attention to grain when collecting Nanhong. Nanhong's lines are very sharp, and all the lines will have obvious angles when turning. This is a very important appraisal standard, and this grain looks clean and tidy.
Texture: Nanhong feels rubbery. Most fake southern reds are basically pure red, and true southern reds are not opaque even if they are all red beads. You can see that the colors are transparent and consistent from the inside out. On the contrary, even colorless beads have a hazy feeling.
Weathering pattern: Old Nanhong will have a half-moon weathering pattern, mainly because of long-term use. How to identify fake south red agate? It can be clearly seen that the surface powder is inconsistent with the pulp fermented by water, uneven and dull, and the grain depth is dull with the weathered grain made by fake south red or new imitation. However, at present, there are no weathering lines in mass-produced dyed Nanhong, and most of them are cracks on the surface of agate when it is directly fired at high temperature.
Perforation: The perforation of the finished South Red Agate has some unique features. It may be that the big material has holes on both sides before beading, and the holes will not be too small. After a long period of use, the wear in the hole is very smooth.
Judging from the shape of finished products and patina, the southern red material is smaller, and the volume of uniform color is smaller, so the larger one will all be used as ornaments, and the smaller one will be used as beads or pendants. In addition to pendants, Nanhong's works commonly include olive beads, round beads, drum-shaped beads, barrel-shaped beads, wheel beads, abacus beads, melon beads, spacer beads, and drop-shaped beads, most of which are round beads, and some are carved by blocks.
The difference with ruby.
First, ruby is different from south red agate. The red jasper in the original stone is basically in a state of "full meat". If you hit it with strong light, it won't be penetrated.
Second, the shell of volcanic tourmaline is almost the same as that of Liangshan Nanhong, but the surface of tourmaline skin with obvious nail lines is generally smooth, unlike the original skin of Nanhong agate with pits.
Third, under strong light, even the fleshy southern agate will have the texture of glass and glue and the unique winding lines in agate, while the ruby and sapphire do not.
