The color of jadeite changes a lot before and after polishing. I finally understand why I should buy old and fine jadeite.

People who have not been exposed to the jade processing process should not know that the production of jade products requires many processes, such as material selection, design, carving, grinding, polishing, etc. Only after a series of processes can jade become shiny and translucent, and the color is bright.

Of course, they don’t know how much the color of most jade can change before and after polishing. When they are in the rough state, their color is not rich enough, nor is it bright enough. After polishing, their color is completely different. This phenomenon is called "color flipping."

The "color change" of jadeite refers to jadeite that is old, fine and colorful. When it is in the rough state, the color is not bright and pure, but after polishing, the color becomes brighter, richer and purer, which is particularly attractive. This phenomenon is also called "color lifting" in the industry.

It is quite common for jade to change color. When many jade raw stones are just cut, the color is not outstanding or stunning. However, after being processed and carved, and then polished and cleaned, the color of the jade will become outstanding and stunning.

Anyone who has seen rough jade knows that the surface of rough jade that has not been polished or polished is gray, as if it is covered with dust. The surface is not smooth and translucent, and the color is relatively dull. At this time, the jade is less ornamental. But after polishing, grinding and cleaning, the surface of the jade becomes smooth and the color is fully displayed.

Although most jadeite has the phenomenon of color change, the color difference before and after the color change is not very large. For example, a light green turns into a deep emerald green, which is almost impossible to see.

When talking about the color change of jadeite, we have to mention another term: Fangtang. This is a description used by the older generation of jade gambling connoisseurs to describe the appearance of the color material after processing. It means that although a piece of jade is not full of color, because the jade is of high quality, fine enough texture, and relatively strong light transmittance, under the illumination of light, the color is scattered inside the jade, making the entire piece of jade look like it is full of color, full and uniform. This phenomenon is also called "a hint of rebound."
