How to identify Hetian jade original stone

First test its hardness with a knife (please don't try it if you are not a local tyrant): Hetian jade's Mohs hardness reaches about 6.5. Generally, when you use a knife, you won't leave any marks. If it is glass or jade with low hardness, it will leave traces, but now many imitations also choose some jade with high hardness, which will also leave no traces.

Second, check the color of Hetian jade: Hetian jade has only four colors: white, blue, ink and yellow. The legend is red, but I have never seen it, so if I meet red Hetian jade, the designation is false. The color of white is from white to bluish white, yellow is from light yellow to dark yellow (including sugar color), cyan is from light cyan to dark cyan, and ink is from ink color to light black.

Third, the value of sheep fat color and yellow hetian jade is higher: sheep fat jade is delicate in texture, and if it is white and frozen, it is the best variety of white hetian jade. Only Xinjiang has it in the world, and its output is very rare and extremely precious. In addition, topaz is also very rare, and its value is second only to suet jade. Blue Hetian jade has the lowest value, and its color distribution ranges from light blue to deep blue, with many kinds and different shades. It is the most colorful of Hetian jade, so the price is slightly lower than other colors.

Fourth, observe whether it is translucent: jade is transparent, translucent and opaque, and Hetian jade is translucent. In the light, it can transmit light, but it can't see the transmitted object clearly. You can aim the jade at the light source and shake it behind the jade with your hands. Really, Hetian jade can see shadows shaking.

5. Listen to its voice: Hetian jade is crisp and loud because of its thick and moist texture and firm pulse. You can knock two identical jade pieces a few times. If the voice is dumb, it is not hetian jade. Hetian jade's voice is as clear as steel.

6. Weigh by hand: When buying, you can weigh the jade with the same volume by hand. Hetian jade is heavier, firmer and thicker, generally heavier than other jade.

7. Check its texture: Hetian jade is moist, delicate and soft, with oily luster on the surface. Other jade is not as oily as Hetian jade. In addition, jade can be placed on the skin, and it will feel cold, while glass products do not.

8. Check its certificate number: Hetian jade is expensive and generally has a certificate. You can call the Quality Supervision Bureau or check online to see if the number is true.
