Green is the common color of jade, and it is more familiar. The color of jade is related to the type of minerals and the content of chemical components. It is mainly caused by the substitution of trace elements such as Cr, Fe and Ti. The higher the color, the darker the color. Transparent to translucent emerald green is related to chrome jadeite, light green is related to a small amount of chrome, opaque green is related to chrome jadeite, some green is related to omphacite, and black is related to chromite and hornblende. Because of this, the green jade has a considerable range of color tone changes. Now Xiaobian introduces several types of green jadeite varieties with high recognition on the market.
Grandmother Green Emerald: Grandmother Green Jade is a kind of green jade, but the green is slightly deeper, less yellowy; green is thicker, the color tone is more correct, its chromium ion content is also a few thousandths, and it also contains a small amount of calcium and magnesium ions.
Emerald Emerald: Contains a few thousandths of chrome ions, emerald green jade is darker than green and green jade.
Yang green jade: contains a few ten thousandths of chromium ions.
Light green jade: very little chromium ion content.
Dark green jade or iron dragon jade, its chromium ion content is higher, above 12.1%. Some black spots in the jadeite are actually black-green clumps formed by thick green enrichment, that is, the merchants say "green does not dissolve."
When the aluminum ion in the jadeite molecule is mainly replaced by ferric ion, the jadeite is grayish green, not as bright and bright as the color of the chrome jadeite, and the oily jadeite belongs to this category.
When the aluminum ions in the jadeite molecule are simultaneously replaced by ferric ions and chromium ions, the color of the jadeite is between the former two, which is determined by the ratio of ferric ions to chromium ions. Such as the jade of the river in the market, is the result of this type of replacement.
The green jade mentioned above is based on the color value: emerald, emerald green, light green, dark green and dark green. Among them, emerald is the best, and emerald green is the second. Most green jadeites contain more or less variegated colors, such as yellow-green, gray-green, and blue-green. If the yellow-green color is very light, it is called boxwood green, which not only does not lose the beauty of jade, but also has its own characteristics; while gray-green and blue-green influence the quality of jade color.
