Identification of the quality of raw jade:

1. Color

Beautiful color is the first requirement and currently the most pleasing. The color is bright green (green). Although the top-grade color is dark green, the green is too dark and makes people feel too dull. Therefore, the top-grade dark green is not as expensive as bright green.

Green jade is the best, and the value of red and purple jade is only 1/5 of green jade. If the jade contains the four colors of red, purple, green and white, it is called "Fu Lu Shou Xi"; if it contains only red, green and white colors, it is "Fu Lu Shou". If it is a single color jade, it is better to have a uniform color. ?

2. Transparency

The level of transparency has a great impact on the value of jade. Transparent jade gives people a cool feeling, but opaque jade, no matter how green the color, feels too dull and lacks vivid beauty. Usually, transparent jade is called "glass type" in the market, translucent jade is called "ice type" or "Guanyin type", and opaque jade is called "hibiscus type" or "taro type".

It is top quality if it is as transparent as glass and has no dirty spots, no chaff or astringency. Translucent and opaque jade are called intermediate jade and ordinary jade respectively. In the Qing Dynasty and before the Qing Dynasty, jade with red, green and white colors was called jadeite. In modern times, jadeite refers to generally transparent jade. Most of the current jadeite jade is transparent and green.

3. Uniformity

The color of jade is uniform. Although it contains white and green, but the color is uneven, the value is very low. The uniformity of color is directly proportional to the value. There is a price difference of several digits between a jade that is entirely green and a jade that is only partially green. The distribution position of the color also has a great relationship. A little green in a conspicuous place is naturally better than green distributed on the edge. ?

4. Shape

The shape of jade can be processed into different styles according to different aesthetic requirements, without special standards. Jade is not valued by weight like other gemstones. Jade is mainly valued based on its shape, size and thickness. The larger and thicker the more valuable it is. On the contrary, the price of small and thin jade will be lower.

5. Photo

Pick up the jade and look at it in a bright light. You can see the color and flaws of the jade at a glance. Sometimes the jade that looks perfect on the surface can only be discovered after taking a photo. to have flaws.

In addition, the color distribution can also be seen through the action of taking a photo, and whether it is a natural color can be determined by irradiation with light. At the same time, synthetic jade (fake jade) cannot escape the "photo" effect. The level is just that this "photo" skill still requires experienced people to be proficient in it. Most people may not understand why.
