The ringworm of jadeite is common in the original jadeite stone, and it is very abrupt in the original jadeite stone, so people in the jadeite industry call it "ringworm of jadeite". The ringworm of jadeite varies in shape and size, such as spots and stripes. According to gemologists' research, the ringworm of jadeite is rich in chromium, which has a great relationship with the formation of green jadeite. During the formation of jadeite, Trichophyton nigrum, which is rich in chromium ions, releases chromium ions that make jadeite green, and chromium ions enter jadeite mineral crystals in suitable geological environment to cause color and form green jadeite. Therefore, there is often the possibility of green jadeite around the ringworm of jadeite, which is called "ringworm eats green" or "green with black" in jadeite jargon. Experts regard ringworm as a basis for judging whether there is green jadeite in jadeite wool. .

If you buy it back, you may cut open the well-colored foot and it will be worth millions at once. It may also be colorless and waterless, and instantly become worthless. This is the risk of betting on stones. "One knife is poor, one knife is rich", a stone may make people rich, or it may make people lose everything overnight.

Experts remind everyone that betting on stones is a contest of experience, strength and luck. With today's advanced technology, no instrument can detect it. Jade raw materials are excavated, and there is a rock shell outside. What's inside the shell is not clear.
