The ancients said that jade can't be cut and gold can't be cut. Jade has been buried underground for thousands of years, and it contains a lot of mineral elements. Therefore, people often say that people raise jade to raise people. If people wear jade for a long time, the water head of jade, that is, the refractive index, will become better and brighter. If a person is in poor health and wears jade for a long time, the mineral elements in jade will be gradually absorbed by the human body, thus achieving the health care function. For example, a lady wearing a jade bracelet usually wears her left hand because it is good for her heart. Jade is the pillow, and the brain is the spirit. Ancient emperors liked to use jade as pillows, and the long-lived emperors in ancient China used jade pillows for a long time. And like Compendium of Materia Medica, there is also an introduction to the health care function of jade.

The benefits of Dai Yu
China has been known as "the country of jade" since ancient times. The ancients regarded jade as a treasure and regarded it as a precious ornament. Ancient medical books say that "jade is the beauty of stone, sweet, flat and non-toxic", and it is considered that jade is the most abundant substance in human body. It is believed that jade absorption can "promote fluid production to quench thirst and remove stomach heat" with the help of saliva and its synergistic effect.
Soothes the troubled place, nourishes the heart and lungs, moistens the throat and promotes hair growth. "Therefore, jade is not only used as jewelry, ornaments and decorations, but also used to keep fit. Since ancient times, emperors and concubines of various dynasties have not used jade to keep in good health, while Song Huizong loves jade and Yang Guifei has jade to relieve the heat.
The health-preserving mechanism of jade has been confirmed by modern science. According to chemical analysis, jade contains many trace elements beneficial to human body, such as zinc, magnesium, iron, copper, selenium, chromium, manganese and cobalt. Wearing jade can make trace elements absorbed by human skin, activate cell tissue and improve human immune function. Therefore, some Chinese medicine practitioners say that "some diseases can be cured not by taking medicine, but by wearing jade often", which is the truth. If you wear a jade bracelet for long-term benign massage, you can not only passively remove the disease of blurred vision, but also store your vitality and nourish your spirit.

Discrimination of jadeware authenticity
Emerald is expensive, and the selection technology is very demanding. It is difficult for most consumers to distinguish its advantages and disadvantages, and it is easy to buy inferior products or fakes with a little carelessness and suffer huge economic losses. There are many jade shops in the market, and jade articles are generally divided into nephrite and jadeite. Emerald is also called emerald. Academically speaking, nephrite is a silicate containing calcium, magnesium and iron; Jadeite is a silicate containing sodium and aluminum.
Here are the advantages and disadvantages of jadeite, and the methods to distinguish between true and false:
Identification method of water → Drop a drop of water on jade, if it is dewdrop-shaped, it is real jade; The water droplets disappear quickly, which is a fake.
Touch by hand → Real jade will feel cold and lubricated if touched by hand.
Inspection method → Put jade in bright places such as sunshine and light. If the color is clear and the green is evenly distributed, it is a real jade.
Licking the tongue → licking the real jade with the tip of the tongue has a astringent feeling; Fake jade has no astringency.
Magnifying glass viewing method → Put the purchased jade under a magnifying glass to watch, mainly to see whether there are cracks. The jade without cracks is the best quality jade, followed by cracks. Even if it is real jade, the value of cracks is greatly reduced. The more cracks, the more obvious and the lower the value.
