Jade true and false identification method:
First, look at the color. Color is the most important factor in assessing jade quality. The color is uniform, yang, thick, and positive jade is the top grade. "Flat" means uniform; "Yang" means bright color, giving people a sense of cheerfulness and no stagnation; "Concent" means darker colors; "Positive" means no other mixed colors.
Second, it is to look at the texture. Jade is a polycrystalline mineral formed by silicate at high temperature and high pressure. The size of its crystals directly affects the smoothness, transparency and hue after honing. Therefore, the finer the polycrystalline structure, the better the texture of jade.
Third, it is to see transparency. Transparency is a physical phenomenon that complements texture. The finer the texture, the higher the transparency. If the jade is as transparent as glass, the fineness of the crystal inside can make the light straight through without being blocked.
Fourth, it is to look after the processing. Jade is mined just like ore. The colored parts of the stone must be carefully cut into different shapes by experienced professional craftsmen, then polished and carved, polished and waxed before they can be sold on the market. The grade A is the highest in the processing without any bleaching fading or dyeing treatment; the grade B is bleached and faded, the value is second; the dyed grade C is lower. Excellent after-day processing can add icing to the jade and double the value.
Fifth, look at the cracks. Cracks in jade may be caused during mining or processing. With a crack, no matter how good its color, texture and transparency, it will affect its value. Sometimes the crack is not obvious on its surface, but it can be seen by careful observation in the sun. Especially for jade that is bleached, faded or dyed, cracks are common.
6. While discerning the quality of jade, it is also necessary to prevent the artificial jade from being fake. Artificial imitation jade is made by dyeing with glass, plastic and other materials. Most of the glass imitation jade contains bubbles, the color is bright and the green is very bright, and the color is different from the real jade. The plastic imitation jade is lighter than the real jade, the transparency is very poor, the color is dull, and it is far from the real jade.
