How to distinguish the stone, how to distinguish the real from the fake

The stone is real or fake. At present, due to the small reserves and high value of Sibin gravel, with the development of the cause of stone and stone, counterfeit stone tools have been listed, and in the past two years, counterfeit stone products have been flooded, which has damaged the rights and interests of consumers.

Suspicious Stone Products:

1. Stone products without national test reports: Some enterprises only have trademarks or test results presented by individual testing institutions on the stone products sold by some enterprises, and there is no test report issued by the national authority. The product trademark is only used as the brand of the stone products sold by the enterprise, and any enterprise can be registered.

What's more, the jewelry appraisal certificate is used to pass off the product medical device license to confuse the public and confuse consumers. Stone refers to a stone that can cure diseases, belongs to the category of traditional Chinese medicine medical equipment (not jewelry), and can only be called a stone after being tested by the national authority to determine that it has medical value.

2. "Stone" products that can be greatly discounted: The cost of raw materials for genuine Sibin stone is very high, and there is not much room for significant discounts. The cost of a fake or fake is extremely low and can easily be discounted at 5 or 4 percent**.

3. Hype up stones of various colors, jewelry appraisal certificates, and other concepts: stones are stones that can heal, but not all stones can become stones. Stone belongs to a class of medical devices of traditional Chinese medicine, and it is the top grade for making traditional Chinese medicine medical equipment.

Color alone cannot tell whether it is a stone or not. There is no "stone" in the national jewelry appraisal standard, so consumers should pay attention to it when purchasing.

4. Various colors of "stone": the main factor that determines the color of the ore is the amount of iron and copper content. If the iron oxide content in the ore is too high, the stone will take on a color such as yellow or red; If the copper content of the ore is too high, the stone will take on a green color; The color alone can not distinguish whether the stone is a stone, many businesses use this to hype the color concept of the stone, shoddy, fake as real, consumers need to pay attention when buying.

5. Relying on the jewelry appraisal certificate and the concept of red, green, yellow and other ore color stealing, it is impossible to provide authentic and reliable, or tamper with the production registration batch number, quality and technical implementation standards, enterprise registration and business location, chemical composition test report, radioactive test report of the relevant national departments, and the unknown composition of the stone will cause chronic heavy metal poisoning after wearing or use, please pay attention to consumers when purchasing.

**:Encyclopedia.

The stone belongs to the traditional Chinese medicine physiotherapy equipment, and the stone usually needs to have a medical device record number. Generally speaking, regular merchants will also take the initiative to show the relevant qualifications of the stone when they make stone products. And the qualification and testing of complete stone products, the price is higher, taking the stone scraping board as an example, a qualified product is usually not less than 100 yuan.

The skills of distinguishing the authenticity of the stone are as follows:

1. The most important thing to identify the stone should be the chemical element analysis, which is what we often call the test report.

The main component of natural gravel is a mineral called "microcrystalline limestone", the most of which is strontium, calcium oxide, followed by silicon oxide, sodium oxide, etc., as well as aluminum, iron, magnesium, phosphorus and other elements, trace elements and rare earth elements contain chromium, manganese, nickel, copper, yttrium and other more than 36 kinds of elements that are beneficial to the human body, and the content of radioactive substances is very small.

At the same time, some stones contain copper, iron and other metal substances, resulting in red, yellow, green and other colors.

2. Look at the stone structure of the stone.

Stone is a kind of pure natural health tool, made of natural Sibin stone hand-polished, in the case of breaking or smashing, the surface of the fracture will show the natural color of natural stone, and you can clearly see the dense structure of the stone. In addition, the hardness of the stone is relatively fragile, softer than the general stone, and it is a fragile product, and scratching it with a hard thing will produce a clear trace.

3. Look at the gloss.

The surface of Sibin stone is fine, the degree of polishing is high, and the particle size of mineral crystals is small, which is about. In addition, when purchasing, you should see the test report of the crystalline granularity of the mineral.

4. Judging by the sound of striking the stone.

The sound of the stone made of Sibin stone is more like the sound of metal, and it is also more crisp and extended, so there is a golden sound of jade vibration, and the sound of other stones is like the sound of drums and gongs, which is relatively dull, and the sound duration is short.

5. Judge from the feeling of touching the stone.

Most of the pseudo-gravel stones are made by mining ore and obtaining ore, and the feeling of holding it in the hand is cold from the inside out; The Sibin stone is a pumice stone on the surface, and has the six virtues of gem and jade of "fine, clean, warm, moist, greasy, and condensed", and has the characteristics of fast heat absorption and slow heat dissipation, which is also one of the reasons why it can be used as a temperature therapy tool.

Excavation process. In 1978, 13 Sibin chimes from the Spring and Autumn period were unearthed in East China, two of which were damaged, which inspired the members of the China National Orchestra Society in Shandong to continue to search for this stone, and in the mid-eighties, the rare Sibin floating chime that had been lost for 2,000 years was discovered.

There are many ways to distinguish the authenticity of the stone, some of which are through external characteristics, such as color, **, etc.; Some are intrinsic attributes, such as ingredients, properties, etc. External features are easy to identify, even ordinary people can easily grasp, while internal attributes cannot be identified by the naked eye and often have to be detected with the help of relevant tests.

Characteristics of the stone.

1) Security: Pass'Crossing the country'The test stones of the authoritative department do not contain harmful substances. At the same time, there should be a state'A medical certificate issued by the Food and Drug Administration'Therapeutic Device License;

2) Ingredients: Contains more than 40 kinds of beneficial people'trace elements and minerals of the body, as well as people'More than 20 kinds of anti-aging elements such as calcium, magnesium, zinc, chromium, strontium, and selenium are essential for the body. There should be a country in this regard'Home Quality and Technical Supervisor'production license issued by the Inspectorate;

3) Far red'Outer rays: Stones have a strange energy field that acts on people'Body** indicates that it can produce a very distant redness'External radiation, its frequency band is extremely wide, far red'The outer frequency can reach a range of 7 to 20 microns.

4) Ultrasound: Stone every rubbing'Wipe people'The body can produce benefits to the body once'Healthy ultrasound pulses, with an average number of ultrasound pulses up to 370'8 times, with a frequency range of 24 million hertz, which is the first of all materials.

5) Microcrystalline structure: It is a calcite microcrystalline rock mass with a crystal size less than that, and its texture is very delicate and rubbing'Wipe people'The body makes people feel very comfortable.

According to official data, at present, the production of Sibin pumice is exhausted, and the relevant industry is **all the way**. The product has generally broken through the 700 yuan mark, it is expected that this rare ore will form a market in the near future, the situation of hoarding will become a common situation, and at the same time a large number of counterfeit stone products will also take the opportunity to occupy the civilian market of the people. According to the estimated budget of the market, the annual output of Sibin pumice stone is less than 10,000 cubic meters, and the annual sales volume of the market has reached 5 million cubic meters, which means that at present, 500 pieces of stone products are sold in the market, and only one is genuine!

Sibin pumice, produced in the shore of Surabaya in Shandong Province today, the stone is dark gray-brown throughout, with jade texture, delicate and moderate softness and hardness. It is superior to the irregular earthy yellow patches mixed with it.

Excerpt from page 42 of "Stone and Health and Beauty".

Lingbi stone is a kind of ornamental stone, and its most significant feature is: the whole body is pure black, and there are sometimes white lines, or it is called "lock", and it can also be used as a chime. But its far-infrared, ultrasonic and acoustic functions are far from being the same as those of Sibin Stone.

What's more, for commercial purposes, and to pass off as Sibin stone, although as a stone seems to be indispensable, but its effect is not the same as Sibin stone, the so-called fish eyes mixed pearls.

How to distinguish the authenticity of the stone:

Far infrared detection: Wearing or using a stone can speed up the blood flow of the human microcirculation by 20%, which is what traditional Chinese medicine calls qi and blood, which can be interpreted as a "far-infrared phenomenon" with modern science.

Crystalline granularity: The mineral crystalline granularity of Sibin stone is small, which is about the fine surface and high polishing degree. Take the gua sha board as an example, the real product can be gua sha directly dipped in water, and there is no need to use gua sha oil.

Medical device certificate: The stone belongs to the category of traditional Chinese medicine medical devices, and only the products that have obtained the approval number of the Food and Drug Administration are regular stones, which can play a role in regulating diseases when acting on the human body.

There are many ways to identify stones, but some methods are not scientific, so we still need to carefully consider which method to use to identify stones. Although the stone can be identified to a certain extent by its color, appearance, feel and other characteristics, the simplest and most reliable way to identify it is to rely on the test report. Stone-related testing includes component testing, infrared testing, ultrasonic testing, mineral crystalline particle size testing, etc.
