According to legend, jade is spiritual and will choose its owner. As a scientist, Dr. Luo thinks it can be explained by science. "Jade contains a large number of floating electron clouds, which can absorb Yin Qi of human body, but will not be released in the form of crystal. The electron cloud has been in contact with the human body for a long time, and it will generate static electricity after absorbing the electromagnetic field of the human body, so that the people in contact have the feeling of electric shock. " He also pointed out that under the influence of electromagnetic field, electron clouds will have different arrangements and their colors will change accordingly. Luo believes that jade with clear white background is most suitable for people who have just started collecting. Because this kind of jade is bright and common, there are few fakes. Dr. Luo believes that jade artworks are all carved by skilled sculptors with the best jade and jadeite, and collectors will not sell them at a reduced price because of the financial tsunami. With more and more attention paid to oriental culture, he predicted that the value-preserving ability of jade would be continuously improved. Jade art treasures are priceless, and real treasures have certificates. In order to avoid buying fakes, he thinks it can be distinguished from the appearance and weight of jade. "The color of real jade is very real, and it will change color when put in your hand. The color of fake jade will appear frivolous, and natural jade is flawless. Everyone should be vigilant. As for the weight, putting real jade in your hand will have a stable feeling, which glass powder, crystal powder and even other stone powder will not have. " Dr. Luo also explained that jade is divided into jadeite and nephrite. Jade is mainly produced in Myanmar, with four colors: white, yellow, red and green, and jade is the best jade. Nephrite is Hetian white jade in Xinjiang, which belongs to old jade. The difference between soft and hard jade is that the color of jadeite will change with the wearer's physique, and nephrite will only become brighter and brighter, and will not change color. He pointed out that collectors generally prefer jade that can change color, and the royal relatives and concubines of the Qing palace like to play with jade. Jade mining can be divided into mountain mines (mountainous areas), water mines (river beds) and sea mines (inland lakes). Emerald mined by water mines is the most common, while sea jadeite is mined at the bottom of the inland lake 200 meters, so it is rare. The more jade meets water, the more transparent it becomes, while the jade mined by mountain mines is opaque. Most people regard transparent jade as the most important thing, but Dr. Luo pointed out that rare jade is attractive and collectible.
