Since ancient times, jewelry and jade have been highly sought after by people. Since it was discovered by human beings, it has been closely linked with the royal family and is regarded as a symbol of power and wealth. Today, people's enthusiasm for jewelry and jade remains undiminished. We always hear that jewelry and jade are good for human health, but few people know that some jewelry and jade seem dazzling, but they are harmful to human health.

Lower zircon

Low-type zircon, named Lower type of zircon in English, is metamorphic zircon (natural zircon, not synthetic cubic zirconia). Gem-grade low-type zircon mainly comes from Sri Lanka and Brazil, and the common ones are green, grayish yellow, brown and orange. Because of its rich and beautiful colors, it is often used to make rings, bracelets, necklaces and other accessories. However, this low-type zircon has certain radioactivity, which will affect the nervous system, cardiovascular system and visual system of human body. Long-term wear will cause tachycardia, bradycardia, palpitation, blood pressure drop, headache and dizziness, as well as sleep disorders, memory loss, cataracts and other symptoms. Although China does not produce natural zircon, and there are few natural zircon jewelry, it does not rule out that some unscrupulous merchants will operate this kind of zircon jewelry, so we must be careful when purchasing.

topaz

Topaz, also called topaz in English, is a silicate mineral containing fluorine, which is easy to crack during processing, has low thermal stability, changes at 400 degrees, and can be dissolved in sulfuric acid after long-term soaking. Topaz is rich in color, which can be roughly divided into blue topaz, yellow topaz, red topaz and colorless topaz. Among them, blue topaz can be divided into three categories: royal blue, London blue and Swiss blue. Royal blue is as quiet as the sea, London blue is black, and Swiss blue is like clear sky blue. Among them, sky blue has the highest value, and the color of natural blue topaz is sky blue.

Many colorless topaz can be turned into various shades of blue after artificial irradiation and heat treatment. Because of this, the blue topaz that is common on the market now is almost always irradiated and heated by colorless topaz. Although, if you choose to buy this irradiated topaz jewelry, you should leave it for more than half a year, otherwise it will also cause radiation damage to the human body.

Dyed agate

Agate, whose English name is Carnelian, is a chalcedony mineral, which is translucent or opaque, with fine stone, rich color, large output and low price, and is deeply loved by people. In order to make agate look more uniform in color, many agates on the market are dyed agates. The raw materials of natural agate are soaked in strong acid dyes and fixed at high temperature. The dyed agate is bright in color, but the strong acid is very harmful to the body, and the dyeing treatment will also cause serious pollution to the groundwater.

Speaking of crystals, we all know that different crystals have different effects on human body, and they are basically beneficial to health. These are crystals. But now there are many artificial crystals on the market, some of which are made of high lead glass and wear for a long time. Among them, lead is really harmful to the human body, which will destroy the nervous system, digestive system and male reproductive system and affect the hematopoietic function of bones.

Inferior night pearl

Although the luminous pearl is fluorite, not all fluorite has phosphorescence, so it can be called the luminous pearl. So there are many luminous pearls on the market, which are formed by soaking ordinary fluorite without phosphorescence in phosphorescent powder. This kind of fake night pearl is extremely harmful to human body, so you should pay more attention when buying it. Natural luminous pearls are of high value, and generally have appraisal certificates issued by national authorities.

Ma Laiyu

Ma Laiyu, English name Malaysian jade, is an artificial imitation jade product, also known as Malaysian Jade and Lu Zongyu. The main mineral is timely, which is made of pure timely or timely crystals melted and added with colorant. Ma Laiyu contains a lot of dyes in the production process, which will be absorbed by the human body if worn for a long time, which is harmful to health. Because of its rich emeralds, delicate texture and good transparency, it is often sold as jade.

Dyed chalcedony

Chalcedony is mostly transparent to white, so it is often used to imitate green jadeite and purple jadeite. In addition, merchants will dye it into green, purple, red and blue that consumers like. This chalcedony treated with chemical dyes, if worn for a long time, will cause harm to the skin and even cause skin cancer. The infiltration of harmful substances into the body can also cause many diseases.

Antique jade

Xiuyan jade is a specialty of Xiuyan Manchu Autonomous County, Anshan City, Liaoning Province. It is named after its origin. Its material composition is complex, not a single jade species. According to its mineral composition, it can be divided into serpentine jade, tremolite jade, serpentine jade and tremolite jade mixture, of which serpentine jade is the main one. Antique jade is made by soaking ordinary chalcedony, glass, marble and other materials with chemical dyes. Long-term wear, in which chemical dyes are absorbed by human skin, will cause great harm to the body.

Dye jadeite with polishing powder

Polishing powder is the colorant of jadeite. This kind of jade fraud is mainly used for low-end jade. Compared with those bracelets whose B+C goods pass through pickling and glue injection dyeing to pretend to be high-grade jadeite, this polishing powder is less likely to arouse suspicion, which is affordable for most consumers and more difficult for laymen to distinguish. Wearing this polished bracelet for a long time will enter the human blood circulation, which is not easy to decompose and is easy to cause skin damage.

Yin-yang emerald

The so-called Yin-Yang jadeite refers to a piece of jadeite, one part of which is the real jadeite with superior materials, which is "Yang", and the other part may be the jadeite with extremely poor texture, which is closer to the natural jadeite after dyeing and glue injection, which is "Yin". Wearing this treated jade for a long time will naturally cause harm to the human body.

It can be seen that most jewels that do harm to the human body are artificial, so we should pay special attention to them when purchasing.
