What is the “fog” of jade? How many colors of common "fog" are there?

When talking about the "fog" of jade, it seems that everyone is confused. In this issue of "Jade Encyclopedia", Cui Zhanggui will talk to you about what exactly is the fog of jade? What colors are common fogs and what effect does fog have on the texture of jade?

What is Emerald Mist?

Between the skin of the jadeite raw stone and the jade inside, there is a semi-weathered transition layer. It is hazy, not as rough as the outer layer, nor as delicate as the inside. We call this transition layer "fog". In fact, it is a mineral, but it is a product of its metamorphosis. The fog of jade is not only white, but also yellow, black and red.

For experts in gambling on jadeite, the fog of the stone is also a criterion for judging the fineness of the meat and the quality of the water. Because some stones have only the skin cut off, a little fog can be seen, but the meat is not yet there, so one can only continue to gamble on the quality of the meat inside.

What are the common colors of fog?

White mist

Generally speaking, white fog will have good color inside and good transparency. If there is green, most of it is emerald green or very pure green. Therefore, experts in gambling on stones generally prefer white fog.

Yellow Fog

The reason for the yellow fog is that there is magnesium oxide in it, but it is not highly oxidized, so the fog will be light yellow. Stones with yellow fog usually have few impurities and a certain degree of high emerald color. If iron ions enter the jade, it may also turn into bluish green.

Black Fog

Black fog is produced because of the presence of iron and chromium elements. There is also a chance that black fog will appear high emerald green, but it is only a chance. It also needs to be judged in combination with the fineness of the fog and the skin, etc.

Red Mist

The last red fog is the least popular because the red color is due to the high oxidation of iron elements, and the jade flesh will often have a gray base.

Well, today we have a preliminary understanding of what the fog in gambling on stones is. Shopkeeper Cui still says the same thing, you need to be cautious when gambling on stones. It is okay to learn some knowledge to increase common sense, but it is far from enough to gamble on stones with only this little knowledge.
