2. The color formation of jadeite is mainly divided into two categories, the first category is primary color, and the second category is secondary color. The primary color is the color formed by the primary minerals of jadeite, among which the formation of white jadeite and jadeite with chromium turning green, manganese turning purple, dark green, dark green and oil blue is related to omphacite or jadeite containing omphacite.
3. In fact, the color of jadeite is mainly caused by isomorphic substitution of trace elements such as chromium, titanium, iron and manganese. The higher the content, the darker the color, and the less the content, the lighter the color. Color-causing elements in jadeite are often unevenly distributed, so local colors may be thick or light, or thick or scattered.
4. The color of jadeite is actually due to the addition of hair color elements, which will make it present various beautiful colors.
5. The color of jadeite can be divided into primary color and secondary color according to its coloring mechanism. Primary colors are caused by chromogenic ions during the formation of jadeite. The secondary color is produced by the influence of foreign colored substances after jadeite diagenesis. The primary colors are: green: caused by isomorphic substitution of elements such as chromium, titanium and iron. Purple: colored by manganese.
6. Pure jadeite minerals are colorless or white, showing various beautiful colors due to the addition of chromogenic elements. The formation of color is the result of mutual replacement of elements in jadeite in the long-term geological process. It plays a vital role in the quality of jadeite.
