No matter what color of jade it is, it must be bright. "White as fat", "yellow as steamed millet", "green as jade" and "black as ink" are excellent summaries of jade color by the ancients. Mottled, dark, not good. Among all colors, green is the best jade. Red and purple are one fifth as valuable as green. Jade with four colors is called "Fulu Xi Shou", and if it contains only three colors of red, green and white, it is called "Fulushou".
thorough
As transparent as glass, it is called jade, which is the top grade. Translucent and opaque jade is called intermediate jade or ordinary jade. Before the Qing Dynasty, red, green and white were called jadeite. Now jadeite jade refers to transparent jade, most of which are transparent green.
keep balance
Same color. The color of jade is uniform. If it contains green but the color is uneven, its value is very low.
Step 4 shape
The bigger, the more valuable and the thicker.
knock at the door
Jadeite often has cracks and cuts, which are generally not easy to observe. If you knock, you can judge the existence of cracks by the clarity of the sound.
take a picture
Emerald has black spots and flaws that are not easy to find with the naked eye. As long as you take a photo with a magnifying glass 10 times under the light (avoid strong light), you can see them at a glance.
In addition, when buying jade, we should also pay attention to the craft. Jade products pay attention to exquisite and unique shapes, vivid images, distinct levels, patchwork and elegant decoration. Use color, be clever because of color. Shallow carving, though flat as a mirror, should be far from Jing Yi. Hollow out, exquisite and realistic.
When buying jade, don't do it in bright light. Because light irradiation is easy to make jade lose its primary color and even cover up some defects. The so-called "beautiful jade under the lamp" is the truth.
