From tens of dollars to millions of dollars. Jade fakes are not only different from jade in some physical properties, but also have great differences in green characteristics. You can still identify it by careful comparison and observation. Australian jade: it is an aphanitic time. Its green is even and delicate, with no emerald, yellow eyes and a sense of floating. Observing with a magnifying glass, there is no orange peel on the polished surface. Its specific gravity is 2.6, which is much smaller than jadeite. Mi language: in season, dark green, with a small proportion. Ma Laiyu: In order to dye it in time, we dye it with chromium salt pigment and iron. Although its appearance is the same as that of jadeite, it can be seen under the magnifying glass of 10 times that the color is contained in the cracks of timely aggregate, and its green color is reticulate, uneven, with colorless blocks and color roots, and its specific gravity is small. Emerald: The dispersion is much stronger than that of jadeite, and it is completely transparent. Green has strong other colors. Mountaineering jade: the water head is sufficient, the green is distributed in dots, blocks and strips, it is not bright, it is gray-blue, there is no halo, the boundary with the ground is obvious, the hardness is lower than that of jadeite, the structure is not fine, and there are many natural hidden cracks. Dushan jade: The color is dark, and the groundwater is short and dry. Nephrite: The specific gravity and hardness are lower than those of jadeite, and the surface is oily, which is smoother and more moist than jadeite. Bird orchid jade: rough appearance, poor polishing performance, dull sound when knocking, while jade is brittle, dark green and dull.

In addition to the fake jadeite products mentioned above, jadeite products sold in the market can generally be divided into two categories: natural and artificially processed products, or further subdivided into four categories: A, B, B+C and C. No matter their stone quality or color, they all maintain their natural colors, which are "green enough to pinch water", "green enough to drip water" and "green like Hollyleaf and banana leaves after a storm" and are not easy to change. The other three (B, B+C, C) are all artificially dyed. The real green is unnatural, dim, evil, floating and colorless, and will change color and fade with time, so it has no collection value. How to preliminarily identify artificially treated jadeite with naked eyes? You can use the following four methods. (1) observation method: Due to the polycrystalline structure characteristics of jadeite, colloid or dye pigment hidden in crystal structure cracks can be observed at high magnification in artificially processed products, and acid-etched reticular surface or impregnated reticular pigment can also be seen. (2) Dropping method: When natural jadeite is dripped with hydrochloric acid, sweat will appear on its surface within a few seconds or minutes, while artificial products do not. (4) Tapping method: tap the natural jade gently to make a crisp and pleasant sound; And knocking on the processed items will make a low and dull sound. (4) Acid roasting method: rub it on the back of jadeite with concentrated acid, then roast it with alkyl red needle, and repeat it twice. If you see the spots turn yellow and enlarge, it is the artificial treatment of jadeite. If the above simple identification methods cannot be identified by naked eyes, infrared spectrum and infrared microscope can be further used for identification.

At present, jadeite imitations can be divided into two categories. One is jade-like products made of glass, porcelain and plastic, which are generally called fakes. Because these materials are quite different from real materials in hardness, specific gravity, fracture and color, they are easy to identify. For example, the proportion of jadeite is 3.34, green is green, even and natural, and there is no color root. These are the main differences from fakes. The second is to use other emeralds as jade. At present, the jadeite fakes appearing in the market mainly include Australian jade (serpentine), dense jade, Ma Laiyu (dyed in time), garnet (calcium chrome garnet), mountain climbing jade, dushan jade, nephrite, Guizhou jade, Wulanchui and so on.
