The simple method is:
Look at the color first. Color is the most important factor to evaluate the quality of jade. Jade with uniform color, sunshine, massiness and integrity is the top grade. "Unity" means unity; "Yang" means bright colors, giving people a cheerful and non-stagnant feeling; "Thick" means dark color; "Positive" means that no other variegated colors are mixed together.
The second is to look at the texture. Emerald is a polycrystalline mineral formed by silicate at high temperature and high pressure, and the size of its constituent crystals will directly affect the smoothness, transparency and color tone after polishing. Therefore, the finer the polycrystalline structure, the better the texture of jade.
The third is transparency. Transparency is a physical phenomenon that complements texture. The finer the texture, the higher the transparency. If the permeability of jade is like glass, the fineness of the crystal inside can make the light pass through without being blocked.
The fourth is to look at the handling of the day after tomorrow. Jade is mined, just like ore. It must be carefully cut into different shapes by experienced professional craftsmen, and then processed, polished and carved, polished and waxed before it can be sold in the market. Those that are not bleached or dyed at all during the processing are "A" and have the highest value; Bleaching and fading are "B", followed by value; The value of dyeing grade "C" is low. Excellent acquired processing can make jade icing on the cake and double its value.
Fifth, look at the cracks. Cracks in jadeite may be caused during mining or processing. With cracks, no matter how good the color, texture and transparency are, it will affect its value. Sometimes cracks are not obvious on its surface, but they can be seen by careful observation in the sun. Especially for bleached or dyed jade, cracks are a common phenomenon. While distinguishing the quality of jade, we should also prevent artificial imitation of jade from confusing the real with the fake. Artificial imitation jade is made of glass, plastic and other materials after dyeing. Glass imitation jade mostly contains bubbles, and the color is bright, and green has a strong light, which is different from real jade. Plastic imitation jade is lighter than real jade, with poor transparency and dim tone, which is far from real jade.
Identify the quality and authenticity of jade articles;
Water identification method drops a drop of water on jade, and if it becomes dew, it is real jade; The water droplets disappear quickly, which is a fake.
Touch it with your hands. If it is real jade, it will feel cold and lubricated.
In the inspection method, jade objects face bright places, such as sunlight and lights. If the color is clear and the green is evenly distributed, it is a real jade.
The tongue licking method has a astringent feeling on the tip of the tongue; Fake jade has no astringency.
Magnifier Watch the purchased jadeite under the magnifying glass, mainly to see if there are cracks. The jade without cracks is the best quality, followed by cracks. Even if it is real jade, the value of cracks is greatly reduced. The more cracks, the more obvious and the lower the value.
I wish the landlord good luck and choose my beloved jade ~
