Secret: "Malay jade" is mostly B, C goods jade

"This is our new product. It is only a few thousand yuan from the high-grade jade shipped from Afghanistan. It has passed through Hetian jade and passed the jade." A jade crafts merchant near the Guangzhou Hualin jade market is a customer. recommend.

Since the end of last year, the jade market has continued to pick up. In the wholesale and retail markets of Guangzhou, the variety of new jade has also increased greatly. Afghan jade, Pakistani jade, Indonesian yellow, and Malay jade bloom. However, the major jewelry testing centers in Guangzhou have successively detected the products that are not on the board: some so-called "jade" crafts are actually the ingredients of marble, and most of the "Malay jade" is dyed jade.

In the March 15 Consumer Rights Protection Day, the industry reminded the public that the new "Jade" decoration home is feasible and has no special collection value.

Investigation: Processing plants are not divided into "stone" and "jade"

As a retailer, he repeatedly talked with the clerk of the above-mentioned stores and learned that their "Afghanistan jade" and "Pakistan jade" were purchased in Yunfu's wholesale market and jade production enterprises.

According to the statement, Shun Teng found the Jinlong Jade Wholesale Market in Yunfu City, Zhaoqing City, Guangdong Province, located near the Public Security Bureau in the downtown area. One of the suppliers of Guangzhou merchants is located in the middle of the market, with a large facade, and its boss has claimed to have been operating the jade business for more than five years. After observing, it was found that the products of four or five merchants in the nearby location were similar, with Pakistani and Afghan jade crafts as their main business.

However, it was only after the talks that the wholesaler was originally a stone-manufacturing company, not a jade processor in the full sense, and stone production and sales was one of the featured industries in Yunfu. I came to a factory where one of the enterprises is located 10 kilometers away from the suburbs and close to the Yunxiao Expressway. The name of the factory is completely named after “××stone” instead of “Jade Processing Factory”, and it is observed in its warehouse and factory. The main products are not jade ornaments, but large stone bricks used for indoor flooring and decorative wall coverings in hotels and other high-end buildings. The area of ​​each block is 1.5×1.2 square meters.

Huang Shifu of the stone company said: "We have been producing stone for more than 10 years. In 2011, we began to process jade ornaments. In fact, the raw materials for the production of jade ornaments from all over the place were originally made of stone. Just after cutting. The size of the area is different."

Stone change "Jade" manufacturers can earn 3 to 9 times more

At the scene, the raw materials for the production of Afghan jade were found. If it was processed into stone of 160 cm × 117 cm, the ex-factory price was less than 2,200 yuan per square meter, but if it was polished to a larger area, round jade, The price is 800~2000 yuan. The volume of the stone used in the former is about 7 to 10 times that of the latter, and the grinding process of the two is not far from the labor cost.

Through calculations, it can be found that if the material is processed into a "jade" decoration, the price can be sold 3 to 9 times more expensive.

Another Li surnamed master said: "Because I used to be good at producing stone, we locals only processed simple jade articles, such as large decorative paintings or jade. Later, the northerners came, there are investments to open factories, and there are also The jade carving master can process more complex zodiac and figure statues, and everyone will work together to produce and sell jade crafts. These things that we originally called stone, as long as they are made of small ornaments, are called jade by the northerners."

Inquired about the production manager and a number of masters, we do not understand the actual chemical and physical components of various types of stone, and it is customary not to distinguish between the concepts of “jade” and “stone”. Back to the commercial street next to the Public Security Bureau, Lin’s boss of a commercial bank said straightforwardly: “We originally only classified products by color, such as garnet red, such as ice snow, but later the retailers in the Pearl River Delta came to buy goods here, hard to say yes. The finest jade, named after the place of origin, we will follow the jade together.” From the surface, the concept of “Jade” and “Stone” is confused, and the people of the place of origin are not intentional, but externally driven by the market. result.

Secret: "Malay jade" is mostly B, C goods jade

On the spot, I purchased a plate made of Afghan jade, together with the ornaments I bought in the jade wholesale market in Liwan District, and took it back to the jade testing center in Guangzhou for testing. According to the instrument identification of Guangdi Jewelry Testing Center, both products belong to recrystallized limestone. The main component is calcium carbonate, which is commonly known as marble, which is also widely produced in China.

Director Xiang Xianyu of the agency explained: "There is no such thing as Afghani jade in geology. If the representative refers to the jade produced in Afghanistan, it should not be the marble produced in Afghanistan, but should be similar to Chinese jade or jade. There are indeed such products sold in the South Asian and West Asian markets."

In the recent investigation of the jade market in Guangdong, it was found that with the recovery of the jade market, various types of jade have also increased, and the number of jade named after a certain place of origin is numerous. In addition to Afghan jade and Pakistani jade, there are many varieties such as Malay jade, Indonesian Tianhuang, and Guilin chicken blood. In addition, there are some new jade species named after jade, as well as Xinjiang silk jade and rose gold jade.

However, in the large-scale testing center's spectroscopic instruments and microscopes, similar products cannot withstand scrutiny. The so-called Malay jade, most of which is dyed and synthetic jade; the so-called Indonesian field yellow, is basically a marble component; most of the crafts called Pakistani jade or Afghan jade, actually still marble. Before the "World War I became famous" in 2010, Huang Longyu was once packaged as "Silicon Field Yellow" by the merchants.

Ordinary stone is called "jade", which is a profit-making action for merchants, especially retailers. One is covered with "foreign" outerwear to increase mystery; the other is to upgrade the grade to sell high prices.

What is the difference between "Jade" and "Stone"?

Dr. Zhang Shipai of the Chinese Academy of Sciences believes that there is a clear distinction between “Jade” and “Stone” in the field of geology and jewelry. Jade must have four characteristics. First, it has a certain transparency. The shape is closer to the glass. It can't penetrate the light like marble or porcelain. Second, it must have a certain degree of moisturization. It is as gentle as jade. Stones, some of the lower grades of white jade or jadeite are actually closer to stones; the third is fine, the internal crystal particles are small, the texture of jade needs to be regular and detailed, and the number of "ribs", "stalks" and cracks should be a bit less. Finally, the cheap "jade" should also have a certain scarcity. It can only be a special product of a certain place. The amount of soil produced by the mine cannot be greater than a specific value; and this is impossible for marble.

    The standard Bladder Accumulator consists of a [closed" rubber bladder inside a forged steel shell. A mechanically actuated valve closes when the fluid has been expelled, blocking off the fluid port, thereby enclosing the bladder within the shell. Where high discharge rates are required, a high flow model is available.Applications with corrosive environments may require shells furnished with an internal and/or external coating or manufactured from stainless steel.
