The name is not too late

In recent years, Gobi stone has become an excellent ornamental stone in China with its unique shape, quality, color and rhyme. In particular, it has many varieties of colors, changeable stone shapes, delicate stone lubrication, gorgeous stone color and intriguing rhyme, and most of them are easy to carry and carry, and now it has become the favorite of the vast number of Tibetan stone lovers at home and abroad.

I. Classification of Gobi Stone

In China's stone appreciation circle, Gobi has many names. I am used to calling it Gobi stone because most of it is produced in the Gobi desert in western China, but some people are used to calling it Fengling stone, Fengling stone, desert varnish, desert stone and so on. Gobi stone can be divided into agate, jasper, chalcedony, Melaleuca, wax stone, chicken bone stone, wood fossil and so on. It is said that there are dozens of subdivisions. For example, agate includes multicolored agate, grape agate, silk-wrapped agate and pearl agate. Jasper includes ruby, green jasper, topaz and black jasper. Desert varnish stone has been used to being called desert varnish stone by stone friends, including gold, desert varnish and various desert varnish stones, or it is called Gobi paint. It is worth noting that although Inner Mongolia and Xinjiang are the two main producing areas of Gobi in China, the Gobi in Inner Mongolia is often covered with this layer of desert varnish, while the Gobi in Xinjiang is not. This is because the mineral composition in Alashan area is different from that in Xinjiang, which is also the biggest difference between the two Gobi.

Second, the causes of Gobi stone

Borrowing the most popular saying at present, when the volcanic eruption forms a large-scale volcanic rock flow and ejects the surface, due to the sudden drop of temperature and pressure, gases such as carbon dioxide and water vapor contained in it quickly escape into the air and condense into rocks, leaving many grotesque pores and cavities in volcanic caves or rocks. In the late stage of volcanic activity, hydrothermal solution filled with silica colloid was pushed up from the depths and penetrated everywhere. Once it gets into the hole or pore of the rock, it condenses into agate, jasper, opal, timely and other individuals, mostly spherical, oval or irregular.

Grape agate, on the other hand, was formed in a large cave near the crater, and a large amount of silica gel hydrothermal solution remaining in countless cracks could not fill the whole space, similar to the diagenetic environment in the cave. Silica gel condenses into beads or water droplets with certain particles, such as sand, soil and water droplets. Birds of a feather flock together, and the latter is attached to the beads formed in advance. Whether hanging on the top of the cave, longer than the bottom of the cave or hanging on the wall of the cave, it has become a string of grapes. In later years, the caves were filled with white mud (also called kaolin), so most of the grape agates were buried in the white mud, which played a very good protective role.

Due to the special geographical environment of the Gobi Desert, the temperature difference between day and night is very large. In summer, the surface temperature reaches 60 degrees during the day and drops to 10 ~ 15 degrees at night. Due to long-term exposure to the harsh environment of thermal expansion and contraction, coupled with years of intense sunshine, wind erosion and rain, the stone body gradually decomposes and cracks into various forms. Later, these stones, which decomposed and split with the matrix, experienced year after year of sand transport, grinding, sun exposure, rain erosion, sand erosion and grinding, and the continuous rise and evaporation of groundwater. In addition, the iron and manganese in the rock gradually dissolve and overflow (unique to Alashan area), forming a layer of reddish-brown iron oxide or black-brown manganese oxide film or other color films on the surface of the stone, which is as beautiful as a layer of pigment. It is also like the patina covered on the surface of antique cultural relics, which is faintly shiny. This naturally formed solid outer film, with a thickness of about 1 ~ 2mm, is called desert varnish by local people. Of course, desert varnish, covered with a golden coat, is the best in Gobi at present, and is called "golden desert varnish" by locals.

Desert varnish not only has the above colorful and natural beauty, but also has a certain protective effect on the original stone itself. The world-famous ancient Egyptian pyramids and the Sphinx still stand proudly after more than 4,000 years of wind and rain, and even the inscriptions on the stones can still be recognized today, thanks to desert varnish. To sum up, after billions of years of deposition, Gobi has a high degree of silicification, and its color is caused by trace metals or non-ferrous minerals, and its shape is mostly related to the generation space. After thousands of years of sand polishing, the density is very high, and hitting the stone with something can make a metallic sound.

Third, the purchase cognition of Gobi stone

Desert stone has only entered the stone industry in China for several decades. The reason why it has been recognized by stone friends and collectors at home and abroad in such a short time is that it is small in shape, easy to form, easy to carry, easy to combine and convenient to place. Good quality, not only high hardness and compactness, but also agate and jasper reach gem level, and desert varnish is smooth, delicate and lubricated; The color is excellent, the Gobi stone is colorful and dazzling, and the colorful agate is often superb; Full of charm, regardless of mountain shape, phase contrast or Zen stone, it is full of charm, unique and unforgettable. According to the statistics of stone fairs all over the country in recent years, Gobi stone is often the most popular, indicating people's preference.

Because the price of Gobi stone was relatively cheap in previous years, you can buy a box for a few hundred yuan, so the general collectors or stone merchants began to experience many collection stages. Later, with the rapid rise in the price of Gobi stone and the gradual shortage of stone resources, people had a certain understanding when they bought it again and began to collect it purposefully. For example, some people buy it to match the collection of the Central Plains at home, some people buy it to sell, and some even spend a lot of money to collect fine products. Personally, at this time, taking advantage of the Gobi fever, collectors who don't want to be long-term can try to sell at a good price; Those who are willing to collect appreciation can try to collect fine products and sell them at a price. Because any kind of stone, when it is hot, means that the stone resources will be gradually exhausted in the near future. According to the herdsmen in Alashan area, the Gobi desert has long since disappeared. In order to find the Gobi desert, people often need an excavator to dig a few meters to dig the Gobi desert buried deep underground. Of course, the color and texture of this excavated Gobi desert are far behind the surface of the Gobi desert.

Four. Shooting, Naming and Matching of Gobi Rock

I remember that in a stone exhibition a few years ago, every time I saw a booth selling Gobi stones, the booth was always crowded with buyers. At that time, in order to buy some good stones as soon as possible, it was always too late to choose carefully, so we always picked out the larger stones with good quality, excellent color and strong charm first, and then bargained with the boss by the pile. I have always thought that if you choose slowly and choose slowly, good stones will often be thrown away and bought by others. But when the stones are bought back, the best side of some stones is often invisible at that time because of the interference of the first impression. My habit is to wash the stones I bought before taking photos. Every stone should be shot from several angles. If you still can't see the best image, you can often get unexpected results by rotating the photo 360 degrees with photoshop software until you choose the best shooting angle.

After the stone body is determined, the next step is to name it. There are several points to pay attention to when naming stones: First, if your stones have a good selling point, or even if the buyer has been positioned as a westerner, or is ready to contribute to the magazine "Appreciating Stone Bonsai" in Shanghai, you should follow the aesthetic view of westerners. Due to the great differences in the cultural basis of stone appreciation between the East and the West, Westerners emphasize "natural beauty", while China people emphasize the unity of art and culture, so naming is bound to have traditional culture or regional color. If someone prefers to use an ancient poem or idiom instead, it is precisely this that makes it impossible for westerners to understand and appreciate the meaning of your name. Second, naming is often divided into straightforward naming and implicit naming. The so-called straightforward naming can make people see at a glance, while the implicit naming requires Tibetans to firmly grasp the charm of stones, and fully reflect the color of traditional culture through naming, which is more intriguing.

Named Linglong

I think the matching of Gobi stone is a little different from that of water stone with larger stone body. This is because the Gobi stone is relatively small, only a few centimeters small, and the seats are not easy to match. Sometimes, it is more difficult to carve the seat according to the proportion of the stone body and the base. In addition, Gobi stone also has the convenience of convenient collocation and combination. Once equipped with a seat, it will be restricted and inconvenient. So some Gobi stones are very suitable to match the stone pedestal. As long as they are swung, even if they are unstable, they can be slightly fixed with plasticine. This saves money and is effortless. Of course, for stone bodies that are inconvenient to combine and match, wooden bases can also be configured. In addition, in order to know what kind of stones to match with what kind of seats before taking a seat, Tibetans can make use of all kinds of seats stored in their computers on weekdays to make a good match in advance until the style and height ratio are determined, and then negotiate with the seating master to make a final decision, which can not only ensure the satisfactory proportion of seat styles, but also play a role in wasting less money.

To sum up, as a stone lover, digital cameras, computers and corresponding computer software are essential tools.

Verb (abbreviation of verb) Analysis of Gobi collection trend

Recently, many domestic stone appreciation journals have published articles on stone appreciation resources, and many experts and scholars have talked about their worries or development trends about the stone industry in China. But in any case, everyone agrees that as far as a specific stone species is concerned, the more people like to collect it, the faster its resource depletion will be. It can be inferred that the resources of Gobi will eventually be exhausted with the great development of stone appreciation history. As Mr. Zhou Yishan said in the paper published in Shanghai Stone Newspaper: "Once some good strange stones enter the collection field, a large part will disappear!" According to the experience of Japanese stone-hiding, more than 60% no longer show up. "Looking at the stone appreciation market in China, it has just started. With the continuous improvement of people's living standards, the popularization of the concept of collection and appreciation, and the increasing promotion and development of the theory of stone culture, the number of people who will join the team of stone appreciation and treasure will increase exponentially in the future. Therefore, a large number of good stones will be hidden in people's homes as fine products. Comparatively speaking, Gobi stone will become the first choice for new and old stone collectors because of its four advantages: small size, good quality, excellent color and rhyme, convenient collection, carrying, handling and matching. In the past two years, some stone collectors in Shanghai, Liuzhou, Hubei, Beijing and other places, including stone merchants in Inner Mongolia, have made special trips to Qingdao to buy stone for many times, which is nothing new and generous. As long as it is a stone that the other party is optimistic about, generally speaking, it will be returned at the price demanded by Tibetans or several times the price when it was sold that year. In addition, it is quite common for stone friends all over the world to buy stones in their own homes, which fully shows that there are fewer and fewer good Gobi stones in the market, and a few smart stone friends and stone friends who are willing to collect and invest for a long time have begun to buy stones in their own homes first. These developments and signs show that in a few years, Gobi will gradually withdraw from the primary market due to the exhaustion of resources, while Tibetans who are still keen on buying Gobi can only enter the auction market or seek to buy from Tibetan friends (secondary market).
