Ways to identify the pros and cons of jade
To identify the pros and cons of jade, the Anglo-American Jewelry Association has four standards of “color, transparency, uniformity and shapeâ€. In China, there are six standards, namely, "color, transparency, uniformity, shape, knocking, and photographing."
1, color: no matter which color of jade, jade must be clear. "White as cutting fat", "Yellow as steaming millet", "green as green feather", "black as ink", is an excellent summary of the ancients on the color of jade. It is variegated, dark, and not good. Among the various colors, jade is preferably green. The value of red and purple is one-fifth of the green. The jade containing four colors is called "Fu Lu Shou Xi". If it only contains red, green and white, it is called "Fu Lu Shou".
2, transparent: transparent like glass, called jade jade, this is the top grade. Translucent, opaque is called intermediate jade or ordinary jade. Before the Qing Dynasty, those with red, green and white colors were called jade jade. Now jade jade refers to transparent jade, which is mostly transparent and green.
3, even: refers to uniform color. The color of jade is more expensive, such as green, but the color is not uniform, the value is very low.
4, shape: the bigger the more valuable, the thicker and more valuable.
5. Knocking: There are often breaks and cuts in jade. These cracks are generally difficult to observe. Knocking on a knock can discern the presence or absence of cracks by the clearness of the sound.
6, photo: There are black spots and cockroaches in the jade that are hard to find with the naked eye. As long as you use the 10 times magnifying glass under the light (avoid strong light), you can see at a glance.
In addition, when buying (you can go to Yuyuan and Jewelry) jade, you should also pay attention to the craft. The shape of the jade products is exquisite and chic, the image is vivid, the layers are distinct, the patchwork is beautiful, and the ornamentation is simple and elegant. With color, it is necessary to make color. The shallow flat carving, although the plane is like a mirror, its scenery is far and near. If you are hollow, you must be exquisite and exquisite.
When buying jade, avoid it under strong light. Because the illumination of the light is easy to make the jade lose its original color, and even cover up some flaws. The so-called "beauty under the lamp" is the truth.
