Jade distinguishes between true and false. If judged subjectively, the daily operation is: to transmit light, to see the emerald characteristics of the internal crystal structure (Hetian jade refers to the flocculent structure characteristics of tremolite cloud), and to see that there is no acid etching texture on the surface of the jade body. Emerald after pickling is generally dull and unclear.

Of course, this operation is based on some practical experience. Beginners are not advised to take it for granted.

To make a rigorous and objective judgment, it is best to go to an authoritative jewelry and jade appraisal institution, use instruments for appraisal, and obtain a definite appraisal certificate through density, refractive index, infrared spectrum analysis and amplification inspection.
