Meet the South Red Jade Agate

Among the many jade varieties, Nanhong Agate is an exotic flower. Its bright red color, warm texture, was born in the mountains and deep mountains, is actually the heaven and earth spirit. The old South Red Agate left over from history has always been cherished by collectors. In recent years, with the newly produced Nanhong agate, the market has become increasingly prosperous.

However, recognizing Nan Hong requires a process that takes care of each other, from the table to the inside, and thinks that when the ancestors discovered Nan Hong, they also experienced similar processes. They compared the common red onyx with luster, hardness, color, and so on, setting a real place for the South Red, that is, eye-catching dazzling, dignified and dignified red.

It is generally believed that the Nanhong industry believes that the Nanhong material is absolutely mineral-clear in the Qing Dynasty. What is the reality?

It should be said that the South Red Agate has been very scarce in the history of the application of human jade, which can be seen in the number of historical artifacts handed down from generation to generation. At present, most of the items in the South are made of beads and a small number of pendants. Ornaments are rare. Even small red beads that are small to the beads are rarely regarded as innocent items. Many of them are broken.

The red instruments that survived in the Qing Dynasty include "red and white fish flower plugs" and "Feng Feng Cup". During the Qianlong period, the selection criteria for carving techniques and jade materials were very high. At that time, a large number of chapped Baoshan Nanhong made it impossible for the collection-level Nan Hong works to continue to be produced. The collection-level works handed down have gradually disappeared from the historical perspective. As for everyone's opinion, Nan Hong is a rare mine during the Qing Dynasty. In fact, the Baoshan mine has been producing Nanhong mineral material, but the material is too chapped, so it cannot be used in jade processing until modern technology applies vacuum injection molding to Nanhong processing.

After the vacuum injection molding, the Nanhong material has good integrity and can be processed in any shape. However, due to manual processing, it is no longer a pure natural gem, and the collection is greatly reduced. Therefore, although there was a large number of Nan Hong works during this period, it did not attract the recognition and recognition of the collectors. It was not until the appearance of good-quality Liangshan Nanhong and Jinsha Jiangnan reds that changed the status quo. return.

After the historical data research and actual investigation, it can be confirmed that the main production area of ​​the Nanhong deposit is in the southwest region, such as Baoshan in Yunnan, Liangshan in Sichuan, and the Jinsha River basin.

The description of Xu Xiake's Travels in the Ming Dynasty described Xu Xiake's visit to a place in Yunnan called the Agate Mountain. He saw a kind of agate embedded in the cliffs. "The color of the moon is white and red, and it is not very big. It is just like a boxing. It is also a vine. It goes deeper with it. Ball, this agate top product, can not be met."

According to research, the agate of the text is now the Baoshan region of Yunnan. Baoshan Nanhong is also the earliest and most recognized place of production. However, due to the geological environment, the materials are often chapped and difficult to make. The emergence of Liangshan material in Sichuan made up for the vacancy in Nanhong Mine, and a certain amount of high-quality Nanhong material appeared. In modern times, some of the top southern red artifacts are based on materials from this area of ​​origin.

Nanhong raw materials have different textures and mineral states due to their different geological environments, and they have different appearances in different geological environments. According to the natural shape of Nanhong raw materials, it can be generally divided into: water red Nanhong, mountain red South, and volcanic south red. In light of the currently known Nanhong materials and the conventional wisdom in the industry, we can divide Nanhong into colors: Jinhong, rose red, cinnabar red, red and white materials, and red materials.

1. Jinhongnanhong, Jinhong is the most precious. The best ones are Hongyan Rujin, whose characteristics are: red, bright, fine, smooth and even. The color is mainly red and red, and it also includes persimmon red, which is known to everybody.

2. Rose red color is relatively brocade purple, purple as a whole, such as the blooming rose, the history is relatively rare, there is a certain amount of emergence in Liangshan South Red Mine.

3. The cinnabar red-red body can be clearly seen from the accumulation of cinnabar points, and some appear to have an approximate flame texture. Some cinnabar red flames are enchanting and have a unique beauty.

4. The color of red, white and red is associated with white, such as the common red and white silk materials, among which the red and white are rare, and the artistic effects can be achieved through cleverly designed carving.

5. The red material is a red material with a colorful texture based on the red color. Because the texture is similar to the red texture, it is called by the players as red.

Collection investment trends With the prices of high-end jade such as jadeite and Hetian jade skyrocketing, the return of Nanhong has attracted the attention of many jade enthusiasts. With the further involvement of collectors and investors, the price of Nanyang Agate soared.

In 2000, the price of a Nanhong old bead was a few yuan to more than ten yuan. In 2005, it reached tens to hundreds of yuan. In 2011, it reached several hundred yuan to a thousand yuan. Among them, the fine old South pumpkin bead is even Has reached over 10,000 price. As a result, Nan Hong's material has risen steadily, from a few yuan in 2000 to a pound in tens of yuan, reaching a high price of tens of thousands of yuan per kilogram or even higher. The industry believes that as a non-renewable resource, the once-abstracting Nanhong agate will have a higher and higher value, and the market prospect is considerable. Especially through the creation of masters of contemporary masters, Nan Hong Agate is also making a difference.

With the maturity of South Red Collection Investment, its market trends are shown in the following aspects.

1. Investing less in the original stone, the finished South Red Rock has a lot of gambling, and some of its appearances look very complete. After removing the skin, it is often found that there is a lot of cracks and it cannot be used at all. The collection of South Red Rock requires more expertise and long-term cutting experience. In some respects, Nanhong gambling is not less risky than jade gambling. Even if you buy good materials, there are still variables and risks in the commissioning process, so investors are turning to Nan Hong's finished products.

2. The price of new products, Nanhong, has been rising. Laonanhong has rarely been handed down. The market circulation is dominated by Meizhu and the artistry is relatively low. The investment value has also reached a bottleneck. The ancient collection of works of Lao Nanhong works in the state-level large-scale museum. There is no way for ordinary enthusiasts to deal with it. With the discovery of the Liangshan Mine in Sichuan, the emergence of a large and complete material for Xinnanhong has made it possible to create collections of the Nanhong Collection, and outstanding works have also been sought after.

3. Contemporary famous artists create investment hot spots For jade carving, there are three principles in the industry evaluation: one is that jade materials are to be used in perfection; the other is the exquisite carving skills; and the third is the artistic charm. The famous jade carving works produced by famous artists have a very good collection value. It is due to the long manual production cycle. Each master has a limited number of works and has a high artistic value. At present, in the jade market, the brand effect has already appeared. Famous brands, brand names, famous jade products and other factors are all increasing the value of jade. At present, a piece of Jinhongnanhong is accompanied by a card. If it is a famous masterpiece, the price is about 200,000 yuan, and some even reach 300,000 yuan or more.

Collection and identification of the advantages and disadvantages of the South Red product identification, and white jade have in common. Collection of white jade, some people pursue white, some people pursue skin color, and some people pursue craftsmanship. The value of the South Red Collection mainly depends on the following aspects:

1. The quality of geological quality is an important indicator to assess the South Red. Such as Chen Yu, "Jade in mind," said: "The body such as cream, refined light restrained, thick and moist, dense pulse." A good piece of red, looks very comfortable, soft, giving a sense of moisture.

The words “body like creamy cream” vividly describe the feeling of being worn or worn for a long time.

"Thick and moist" refers to its thick, translucent to slightly transparent texture and luster. Gloss is the ability of South Red to reflect light. The texture of Nanhong is different, and the gloss is different. In general, dense light has a strong sense of quality, and a thick, weak light. Nanhong is significantly different from other agates in that it is bright and shiny with other agates, while the good Nanhong is warm and lustrous. This texture is one of the important characteristics of South Red. Nanhong has a special sense of plasticity and heavy feeling, and is a jade texture.

"Strengthened veins" means that the texture of jade is solid and dense. Nan Hong is hard and delicate. The sculptors also reflected that Nan Hong's sculpture was very different from other agate artifacts, but it was close to white jade. When processing, the sculptors feel good material, delicate and have a certain toughness, can display a very delicate craftsmanship in Nan Hong carving, and the performance of the finished product is also very strong.

There are a lot of classifications about the red of Nanhong, both the familiar "Persimmon Red" and the "Pumpkin Red", and the red and pure Jinhong that appeared in the modern Xinkangkou. What is really good red in the end?

Combining the proportions of various reds appearing in the Nanhong ore, in general, in the case of the same or similar textures, the brooch with the red is the most precious, and the steady red rose is also the leader. Even if it is all similar red, it depends on the degree and purity of red. Red, such as boring or black, will affect the value of South Red. Red is not moist, commonly known as "red," but also affects its value.

2. The complete degree of Baoshan Nanhong was announced from the middle of the Qing Dynasty. There was only one reason: cracking. Only one "crack" has declared the demise of a material, indicating that even if it is not beautiful, if it can't become a device, it can only be a symbol and it can't enter the room. Many of Baoshan's current materials are vacuum engraved and then engraved. Relatively complete materials are very rare, and they are often heard to say that "no crack is not Baoshan material." In recent years, with the excavation of the Nanliang Liangshan Mine, a very complete bulk of material has changed the status of Nanhong’s many cracks. Since the release of Liangshan Nanhong, it has been accepted by expert masters and has been sought after by Tibetan friends. The degree of completeness is an important reason.

3. The embodiment of body mass is the size of the device. In the South Red Collection, the size of works is an important parameter for its value. Historically, the southern red artifacts were mainly based on the bead, and the reason was also limited by the size of the Nanhong material. Collection of South Red definitely needs to have a certain amount of body. In the case of other indicators are excellent, the bigger the better, the rarer it is, especially the South Red.

4. The carving process “Jade is not a good thing”, “Although jade is of good quality, lies in the stone, it is not worthwhile, and it is not different from the rubble”, which means that if there is no master craftsman like a master craftsman, it is very difficult for a jade to be carved. Reflect its true value. As one of the core indicators for evaluating Nanhong devices, the engraving process is sometimes more important than color.

With the rise of market prices, South Red Authenticity and the use of counterfeit substitutes on the South Red Agate can be seen everywhere on the market. The following are common types.

1. The principle of Artificial Burning Artificial Burning is that the agate component contains a small amount of chromogenic ions, and if it contains only Fe3+ ions, the agate will show a natural red color, and if it contains only Fe2+ ions, it will appear blue green. Most agates in nature contain both Fe3+ and Fe2+ ions. In an oxidizing atmosphere, Fe2+ is oxidized to Fe3+ by a simple heating method, thereby turning gray agate into red agate.

Burning red agate, that is, the collection of Dong Hong agate, from the senses and the South Red Agate has a clear difference. Burning red is not entirely natural. Red is dark, not bright, red has a feeling of floating on the surface. From the texture, because the red-on-burning agate is processed with some light-colored agates, this type of agate from other origins does not have the unique rubbery feeling of the Nanhong agate, that is, a sense of grease, and usually has a high transparency and a strong sense of glass. The moist red nature of Nan Hong is fundamentally different.

The main differences are as follows: The material is brittle, and it is prone to the appearance of glass-like buns; color boring, commonly known as dead color, lack of clear sensation, unable to achieve truly pure and beautiful red; there are subtle fire robberies under the microscope, which is caused by high temperatures.

2. Artificial Staining Some agate stones have higher iron content and become red after heating. However, most of them have no such conditions. Therefore, the second iron or oxidized first iron solution should be used for one month after impregnation. ** Soak it for about two weeks, allow it to dry, and heat to acidify it, turning it red. Artificial coloring has a long history in agate optimization and there are certain difficulties in recognition. The stained agate is observed under a high magnification magnifying glass, and can see the distribution of the color of the mesh along the gap between the crystals. The glass has a strong sense of sensation, and there is no special sense of fat in the South Red.

3. Manual injection glue injection is an optimization method that has emerged in modern Nan Hong. It is easier to identify the original stone that has been glued, and there is a transparent inclusion in the outer layer with fine bubbles present. After engraving, the red plastic eye is difficult to identify. Careful observation will reveal a transparent threadlike line in the interior. Usually this kind of transparent thread is relatively straight, and it usually has a long penetration, even through the whole. This transparent line pattern and the natural texture of the Southern Red have some differences, is caused by the wound epoxy glue filling.

4. Red Pikite Red Pikite is a chalcedony that contains mineral impurities such as clay minerals and iron oxide in the composition, and chicken liver stone and goat liver stone. Liangshan Nanhong Production Area also produces a large number of red pebbles, of which one type of volcanic red pebbled hull and Liangshan Nanhong are almost identical, and can not be judged and identified correctly from the outside. The outer layer of the volcanic purplish stone also has high-temperature oxidation brown to iron black hull, different sizes, both as small as beans, there are large tens of kilograms of rough stone. The integrity of the volcanic red pebbles is very good and there is almost no cleavage. The toughness is higher than Liangshan South Red, and it is difficult to break with conventional strength. The cross-section grainy texture is strong on the sand surface, with poor gloss and no fat. The color is mainly red, with black specks. Under sunlight, red pebbles are opaque, and even under the special light flashlight for jade, the stone is barely translucent.

5. Material feeder can be made transparent, semi-transparent or even opaque as required. The biggest difference from natural red is that it is non-oily, and there are certain bubbles under high magnification magnifying glass. The physical properties of the feeder are relatively brittle, and the section becomes a glassy mouthwash.
