Why does the human eye sometimes perceive the color of jade differently?

Many people may know that the color and texture of jade are magical, especially the "death in light" effect of violet jade, which is a rare phenomenon in optics and aesthetics. In addition to violet jade, other jades also have some surprising natural effects.

Many people have had this experience and feeling: during the shopping process, the color of the jade jewelry they chose is very beautiful and moist. But after purchasing it, when I used the jewelry myself, I felt that the gorgeous feeling at that time was reduced a lot. This is actually not surprising.

Jade, especially high-grade jade, translucent or highly transparent items, like other gems and other objects, their original colors will give people different perceptions under different light sources, different light intensities, different lighting conditions and environments. Moreover, because the internal structures of the two jade pieces are different, even if they are the same color, the human eye will feel different when exposed to certain ways of light.

Regarding the changes in color of jade jewelry, the jade industry generally has traditional sayings of "passing the liquid" and "observing the liquid". The so-called "liquid through" means that when the jade is placed flat, it may not be beautiful or eye-catching when we look at it, but if we hold it up to the light (or natural light), it will become eye-catching emerald green and quite beautiful. On the contrary, there is another kind of jade, if you hold it up and expose it to light, its emerald green color will be dispersed by the light and become less beautiful. If you look at it flat, you will see a lovely and beautiful green color, which is called "Chaye".

When we buy a piece of jade jewelry, we must carefully observe its color and transparency. Not only should we do this in a shopping environment, but we should also observe and feel it under natural light to avoid regrets caused by large visual errors due to different lighting conditions and environments. The "flowing liquid" and "observing liquid" of jade are actually not that complicated. To put it simply, this concept is reminding us to observe jade from all directions under as many light sources as possible, so that the jade we buy will be the most satisfactory.
