Jade purchase considerations
Note on the purchase of jade articles:
1. When you pick jade on the dazzling jade stall and can't tell the difference between true and false, you can take the material on the spot and drop a drop of water on the jade. If the water droplets are dewdrop-shaped for a long time, it proves to be true jade; if the water drops disappeared at once, it means that it is a defective product or a fake.
2. Perception. When picking a jade, you can touch it back and forth by hand. If you feel a cold and lubricious feeling, it may be true jade, because the true jade has this nature.
3. Pick up the jade that you are looking at and look at the light. If the color is clear and the green is evenly distributed, it means that it is true jade.
4, if the jade vendor allows, you can use the tip of your tongue. Real jade has a sense of guilt, fake jade does not have this nature.
5. If you choose jade in the informal jade market, it is best to bring a magnifying glass. Because the magnifying glass can distinguish the goodness of the jade. Under normal circumstances, put the jade under the magnifying glass, if it is true jade, less cracks or cracks are good jade. If the crack is large or large, it proves to be inferior.
In addition, if you don't have any knowledge about jade, or don't have much confidence in buying good jade in the informal market, then when you go to see jade and buy jade, it is best to bring a friend who knows jade to prevent eating. Dumb loss.
