What color of jade is the best? What are the factors that affect the green tone of jadeite?

So what are the factors that affect the green tone of jadeite? First of all, the factor affecting the green color of jade is transparency, that is, the quality of water. Good transparency can bring out the gorgeous and bright jade, and its value is high. In addition, impurities and harmful elements such as iron, manganese, titanium, etc. can make jade take on a bluish hue and make the bottom gray or even completely black, affecting its value. Furthermore, the presence of albite, hornblende, zeolite, nepheline, chromite and iron oxide can cause white cotton, black spots, black blocks, etc. in jade, which are also harmful minerals. The more uniform and pure the green color of jadeite is, the higher the content of magnesium and calcium will be. Jade of good quality is created by multiple geological dynamic actions and thermal wave activities.

1. Iron and other impurity metal elements: Iron and other ferrous metal elements penetrate into the green tone of jade, making the brightness of the jade green deeper and darker. It will also affect the saturation (purity) or brightness of the jade, making the green tone of the jade unable to emit pure green gem light, making people feel a grayish green, inhibiting people's vision, and failing to produce a bright feeling.

2. Impurity minerals: such as hornblende, albite, sodium chrome pyroxene and zeolite, not only affect the brightness and saturation of jade, but also turn the green color of jade into gray-green, dark green or even black. The presence of these impurity minerals will also make the green color of jade uneven.

3. Color-causing chromium ions: Too high or too low chromium content will affect the brightness of green. Too high a chromium ion content will make the green color of jade darker, and cause black spots, black threads and black spots inside. Too low a content will make the green color lighter, thus affecting the value of jade.

4. Type of jade: The uneven grain size and loose structure of jade not only affect the transparency of jade, but also cause uneven distribution of jade green. Jade has small and uniform grain size, tight structure, small gaps between particles, and the chromium ions can be evenly distributed in its crystal lattice. At this time, the emerald green is uniform and bright.

5. The water of jade: When the water is good, the green of jade appears lively and energetic; when the water is poor, the green of jade appears rigid and dead, which affects the expressiveness of the green.

6. The thickness of jade: If you want the green color to be neither too dark nor too light, you need to adjust the thickness of jade when the brightness (depth) of jade is consistent. However, the shape and thickness of the green color in the jade cannot be changed. If the green is light and there is no thick green part in the jade to add to it, the thickness cannot be adjusted.

7. The influence of vision on the green color of jadeite: This is related to the issue of color and visual perception. In our vision, we can find that the same color entity often produces multiple color sensations. The same area of ​​black and white appears that the white is larger and the black is smaller. When the green jade jewelry is set against the snow-white background, the green looks particularly bright. But if placed against a gray background, the green would not be so beautiful. However, when observing colored gemstones, using gray objects as a background is the most reasonable approach for observation and evaluation, and is equal to both buyers and sellers. This is an optical illusion created by the human eye.

8. Psychological factors: While color exists in its physical properties, it also affects the function of people’s psychological activities due to the environment they live in and their mentality at the time. When people are in a low mood and the weather is cold, they react slowly to the color green and their color discrimination ability decreases; when the sun is bright and the mood is good, they react sensitively to the color green and have a delicate sense of color. Therefore, when evaluating or purchasing weak jadeite, you must remain calm and not be influenced by external factors.
