How to verify the authenticity of the stone!! How to distinguish the authenticity of a stone

1. Look at the qualifications (various licenses).

2. Look at the condition, color (really similar to stone, delicate feel) 3. Listen to the sound (the real sound is long).

4. Temperature (really fast heat absorption, slow heat dissipation.) Fake slow heat absorption, fast heat dissipation) like you recommend Toudao.com China's first stone product shopping platform. Absolutely.

A percussion sound is crisp.

Second, look at the stone delicately and moistly.

Triple use It is very comfortable after scraping.

The third point is a very important point of judgment.

First, look at the stone structure of the stone is a pure natural health tool, made of natural stone hand-grinding, in the case of breaking or smashing, the surface of the fracture will show the natural color of the natural stone, and can clearly see the dense structure of the stone. The hardness of the stone is relatively fragile, softer than the general stone, it is a fragile product, and scratching it with a hard thing will produce a clear trace. Second, judging from the luster of the surface of the stone**The rough stone of the stone is gray-black after pure manual polishing, and it will become black and oily after long-term absorption of human oil, which is a black stone.

At present, the stones used in hospitals and scientific research institutions are all made of black stone, and no other color stones have been found to have been tested in clinical and scientific research. Simply identifying the authenticity of the stone by its color is unscientific and is completely the personal speculation of some traders. The gloss of plastic pseudo-gravel is brighter and very light, which is obviously different from the natural luster of ** gravel.

3. Judging from the feeling of touching the stone, most of the pseudo-stones are made after obtaining ore from mining, and the feeling of holding it in the hand is cold from the inside out; The real 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. In addition, because the stone is a argillaceous limestone structure, you can clearly feel that the surface of the genuine stone is smooth and soft, and its fineness is ten times that of jadeite. Fourth, judging from the sound, the real stone sound is more like the sound of metal, and it is also more crisp and extended, so there is a golden sound of jade vibration, around the beam for three days, and the sound of other stones is like the sound of drums and gongs, which is relatively dull, and the sound duration is short.

The authenticity of the stone can be verified in the following three ways.

Drug Administration Equipment: Stone is a stone that can treat diseases, belonging to traditional Chinese medicine physiotherapy equipment, so when purchasing, you must go through formal channels, choose a regular business with stone production qualifications, and the manufacturer approved by the Food and Drug Administration is more reliable. At the same time, see the medical device record number of the stone product.

Test report: It is difficult for ordinary people to distinguish the authenticity of the stone through its appearance, so it is necessary to check the relevant test reports of the stone when purchasing, such as component test reports, infrared thermal image test reports, and ultrasonic test reports. Only stones that have passed composition and radioactivity tests by authoritative departments to ensure that they do not contain harmful substances and contain strontium and rare earths can be used as gravel**.

Stone workmanship: The raw material of Sibin stone is natural Sibin pumice, the original crystal particles are small, the quality structure is the most delicate mud crystal structure, the density is gram cubic centimeters, similar to metal crystals. Its texture is very delicate, and rubbing against the human body makes people feel very comfortable.

The inferior "stone" has large crystal particles, hard texture, and rough feel.

How to identify:

1. Look at the medical device license of the stone.

2. Look at the crystalline granularity of the stone.

3. Look at the ultrasonic parameter test report of the stone.

4. Look at the far-infrared effect detection of the stone.

Low-priced stone = inferior stone + evasion detection.

The reporter bought some "stones" randomly from the Internet at about 30 or 50 yuan each, and entrusted the testing center of Tsinghua University to carry out elemental testing on the purchased "stones", according to the test results compared with the test report published on the **, hardness, quality and chemical elements and other data do not meet the characteristics of the stone advertised by the business. There are no infrared thermal image changes and rare earths and trace elements such as strontium, titanium, chromium, manganese, zinc and other rare earths and trace elements that are beneficial to the human body. In addition, the red or brown "gravel" of some merchants** contains heavy metals such as lead and other harmful substances.

However, such merchants usually evade testing or use the "Jewelry Appraisal Report" to secretly change the concept, and the "test report" they provide is mostly forged, or the test content does not meet the health requirements at all.

**The price of the stone is not low, don't try to hurt the body cheaply.

Stone is a general term for stone medical devices in traditional Chinese medicine, and the Sibin stone made of Sibin pumice stone is the top grade of stone products. The stones in the market are mixed, with dozens of dollars cheaper and hundreds of thousands of expensive. Due to the high cost of raw materials for the first stone, the product has to go through testing, transportation, processing, sales and other links before it is listed, and the cost is usually not less than 100 yuan, so there is not much room for discount.

On the other hand, the cost of many fake "stone" raw materials is very low, and the use of industrial building stone is shoddy, and even the detection link is omitted, so it can be easily discounted at a low price of 5% or 4%. Consumers should keep in mind the principle of getting what you pay for, and pay special attention to low-priced or heavily discounted stone products.

There are three tricks for low-quality stone hype: color, origin, and standard.

Sibin pumice, the true color of Xuanhuang", this is the description of the color of the raw material "Sibin pumice" in the ancient book, and the "Xuan" referred to here is interpreted as "black" (Xinhua Dictionary 542 pages). The skin of Sibin pumice rough stone is gray and yellow, but it is black after being polished and polished, and it will become black and shiny after long-term absorption of human body oil, which is a black stone. Because many consumers don't understand the word "Xuan", merchants interpret the word as red or brown to sell their own three-no products.

Therefore, judging the purchase based on the color of the stone alone is the hype intention of some traders.

**The raw material origin of Sibin stone comes from the ancient Surabaya Basin, the ancient Surabaya Basin flows through many provinces, does not refer to the current Surabaya City, Beijing is not necessarily roast duck, and the Surabaya product is not necessarily the stone. Now some businesses in order to make huge profits, regardless of the health of consumers, crazy tampering with and hyping the "stone origin concept", all kinds of stone quality is unknown, rough appearance, specifications are not.

1. The crazy birth of stones of various colors has led to the fallacy that the stones of "Surabaya" are called stones, and that stones can cure diseases.

According to the reporter's investigation, there is no unified national standard for stone products as medical devices. And some businesses boldly use the name of the state unit to frantically hype their own various stone product standards. The ultimate goal is to be driven by profits, so that consumers pay more out of their pockets.

**Self-news.

There is basically no real one on the market.

Characteristics of the stone.

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.
