Recently, the jewellery market has a retro style, and the crystal-clear green jade jade bracelet has once again won the favor of people. But the careful people found that the "green" on their jade jewelry became bigger. how did this happen?
Emerald green and "chrome" content have been studied. In general, the green on jadeite does not change because there is no life. However, the "green" of jade jewelry does show signs of a slight enlargement under special circumstances.
Emerald is usually referred to as gem-quality jadeite, whose mineralogical name is sphagnum. Pure sodium pyroxene is colorless, and once added with chromium, pure sodium pyroxene will appear green. Therefore, whether natural jadeite is green or not is related to the presence or absence of "chromium" elements in the formation of jadeite.
According to experts, the more "chrome" elements, the greener the color of jade. However, jade jewelry such as jade bracelets and jade necklaces are products made from pure natural jadeite. The content of internal “chromium†has been relatively fixed, and its green color should not change. That is to say, even if its raw materials are obtained from mines or rivers, the content of chromium is basically fixed after artificial carving.
The sweat changes the green of the emerald: but the chromium in the jade is not completely fixed. People feel that the green is “longâ€, in fact, because the chromium inside the jewelry has a small amount of diffusion, and the green “long†jade jewelry mainly includes jade jewelry, jade bracelets and jadeite items, which are in close contact with the skin. .
Why is there such a change? The currently accepted explanation is that because the human body has a certain temperature and sweats when heated, the acid and alkaline components in the sweat will penetrate into the jade through the micro-cracks of the jade jewelry. These components may chemically react with chromium ions, or dissolve the chromium ions that have been consolidated in the jade to cause flow migration, so that the green color of the jade becomes "long" and "large". In addition to some changes in green, the pattern of jewelry will change slightly, and its value will not change.
Tips: Myanmar is a jade kingdom. 95% of the world's jade is produced in Myanmar, especially high-quality jade is produced in almost 100% of the country. In addition, according to the isotope study of ancient jade, it has output in the United States, Russia, New Zealand, Austria and other places. At present, the jadeites on the market are basically produced in Myanmar, hidden in the ground for tens of meters or even hundreds of meters, all by manual excavation and transportation.
