Bian Shi's scam was exposed. Buying fake Bian Shi is harmful, and it is very dangerous from the perspective of material selection. In Sibin, marble or industrial waste is used to make pumice, and various products are made into the market without testing, winning the attention of users at a price. This inferior "Bian Shi" has no effect after use, and may also cause human discomfort and even heavy metal poisoning. Bian Shi has natural far infrared rays and has no toxic or side effects. Although it is a good thing, the market is chaotic now, and there are so many holidays. False stones can not only play a health care role, but also have a negative impact on the body because of harmful radiation. For this reason, I have paid a lot of tuition fees in the past two years, and summarized the following four tricks commonly used by border stone vendors for your exchange to avoid being cheated: 1. The red and yellow stones are not bian stone at all, but a local ore called Fuguihong in surabaya county. Of course, all black stones are not necessarily bian stone. As far as I know, there are many cheap black stones with unknown composition. Industrial Blackstone also contains heavy metals, which is definitely bad for your health. Second, the price: At present, there are many fake stones in Sibin, but there are really few. Dozens of dollars of stones in stalls and Taobao are mostly untested products. It is said that manufacturers pay tens of thousands of dollars for a formal test, and fake stones sell you dozens of dollars. He said the ingredients were reliable. Do you think it is reliable? You can't be superstitious about prices, and you can't be greedy for cheap. After all, your body is your own. Origin: The pumice in Sibin refers to the "face stone on the bank of Surabaya" and refers to the Surabaya River basin, not the present surabaya county. Therefore, Bian Shi has nothing to do with the concept of origin. Whether Bian Shi relies on component detection is the result of artificial speculation. Therefore, the statements such as the certificate of origin and the certificate of collection are mostly self-hype of the merchants. 4. Certificates: Stealing the concept by using the jewelry appraisal certificate (because Bian Shi is not jewelry) is the usual trick of the "Three Five" products. The purchase of Spinstone depends on the medical device registration certificate, and larger brands will have production licenses and quality standards. If there are none of the above, at least look at the inspection report of the manufacturer's batch of products (see the inspection unit clearly, some manufacturers forged this piece with copies). At present, there are few formal and reliable Bian Shi brands on the market. If possible, it is better to buy them after seeing the real thing. Generally, fake stones are very different from real stones, which can be compared from workmanship to feel. As long as you are not superstitious about the color and origin of bian stone, and are not greedy for petty gain, you will not give fake stones an opportunity.
