True ancient jade identification masters will definitely take the raw pit jade in a certain environment from raw plate to maturity, so as to understand the special essential characteristics of the shell performance at each stage, and then understand the common essential characteristics of the shell performance at each stage.
True experts in ancient jade identification will definitely take the raw pit jade of different environments from raw plates to ripening, so as to understand the special essential characteristics of the shell of the environment.
True ancient jade identification masters will definitely summarize from the special essence of the shell in various special environments: the common essential characteristics of the shell ancient jade in different environments. The experts of the museum do not deal with the ancient jade of various environments, so they do not know the above characteristics, that is, they do not understand the movement of the ancient jade material. Where does the right idea come from? Where does the correct ancient jade identification idea come from? Where do the correct ancient jade identification standards and methods come from? It can only come from practice, only from the practice mentioned above. Experts do not have this practice, where is the correct ancient jade identification idea? Where are the correct ancient jade identification standards and methods?
This piece of jade belongs to the essential characteristics of the excavated old heirloom and played with the semi-ripe high ancient jade skin shell.

Figure 2
Figure 3, some parts of the frame of the very small point reflection light, concentrating, density tight, slightly hard and bright, micro oil, slightly wet, slightly thick, with tough changes in lustrous luster, etc.; point reflected light characteristics and comprehensive characteristics with the change of the pulp, etc.; the reflected light of the point is arranged vertically and horizontally irregularly. The reflected light density of small surfaces is tight, slightly hard and bright, slightly oily, slightly wet, slightly thick, with changes in toughness and lustrous luster.
Figure 4: Imitations. The reflected light of the dots and small patches of light does not have the aging characteristics and ripening characteristics produced by the shell.
Figure 5, from some parts of the frame of the very small point reflection of light, concentrated light, density tight, slightly hard and bright, micro oil, slightly wet, slightly thick, with toughness changes of lustrous luster, etc.; from the small block of reflected light, micro oil, micro wet, slightly thick, vertical and horizontal irregular arrangement.
Figure 6: Imitations. Judging from the reflected light of the dots and small patches, the pearlescent aging characteristics and ripening light characteristics produced by the skinless shell.
Figure 7: Judging from the reflected light of some parts of the frame and the small blocks, the inability to imitate the light characteristics of the ancient jade shell is more obvious.
Figure 7: Imitations. From the reflected light of the points and small patch surfaces, there are no aging characteristics and ripe light characteristics produced by the shell.
Figure 8: From the reflected light of some parts of the frame and the small surfaces, the aging characteristics and cooked light characteristics produced by the ancient jade shell are more obvious.
Figure 9: Imitations. From the reflected light of the points and small patch surfaces, there are no aging characteristics and ripe light characteristics produced by the shell.
Figure 11: From the reflected light of some parts of the frame and the small blocks, the aging characteristics and ripe light characteristics produced by the ancient jade shell are more obvious.
Figure 12: Imitations. Judging from the reflected light of the points and small patches, the aging characteristics and mature light characteristics produced by the absence of ancient jade skin shells are more obvious.
Figure 13: From the reflected light of some parts of the frame and the small blocks of surface, the uncopable aging characteristics and cooked light characteristics produced by the ancient jade shell are more obvious.
Figure 14: Imitations. Judging from the reflected light of the points and small patches, the aging characteristics and mature light characteristics produced by the absence of ancient jade skin shells are more obvious.
Figure 15: From the reflection light of some parts and small blocks in the frame, the aging characteristics and cooked light characteristics of the ancient jade shell are more obvious.
Figure 16: Imitations. Judging from the reflected light of the dots and small surfaces, there are no aging characteristics and ripening characteristics produced by the ancient jade shell.
Figure 17: From the reflected light of some parts and small surfaces in the frame, the aging characteristics and cooked light characteristics of the ancient jade shell are more obvious.
Figure 18: Imitations. Judging from the reflected light of the dots and small surfaces, there are no aging characteristics and ripe light characteristics expressed by the ancient jade skin shell.
Figure 19: From the reflected light of some parts of the frame and the small blocks, the aging characteristics and cooked light characteristics of the ancient jade shell are more obvious.
Figure 20: Imitations. Judging from the reflected light of the dots and small surfaces, there are no aging characteristics and ripe light characteristics expressed by the ancient jade skin shell.
Figure 21: From the reflected light of some parts of the frame and the small blocks, the aging characteristics and cooked light characteristics of the ancient jade skin shell are more obvious.
Figure 22: Imitations. Judging from the reflected light of the dots and small surfaces, there is no aging characteristics and ripe light expressed by the ancient jade skin shell.
