1, touch

Jade is a good conductor of heat. Real jade, heat conduction is very fast. Jade only plays a conductive role, and energy is still conserved. Wearing jade, or holding it in your hand, makes you feel cool for an instant. Jade is equal to body temperature in a short time because of its good conductor properties. Then expose it to the air, and you will find that it will return to its original cool temperature in an instant.

Step 2 look

Jade is translucent, and some are a little green, which is usually called "Cui". The more Cui, the more valuable. Some live jade was only a little green when it was first bought, but it has been worn for a long time. The longer the jade will grow, the bigger the jade will appreciate accordingly. This jade is green and dripping, and it is still growing.

Step 3 knock

If you have a real jade in your hand, knock it with a stone that needs to be identified. If it makes a crisp sound, it is probably real jade. If the voice is quite rich, congratulations on being fooled and buying a fake. However, when you knock on jade, don't take it directly with your hands. You should tie the two together with a thin thread, and then swing the thin thread to make them collide.

Step 4 burn

The five unique cheats to identify jade are simple in front and complicated in the back, but they are also more awesome. The fourth method is to take advantage of the thermal conductivity of jade, unplug a long hair, and then tightly wrap it around the surface of jade and burn it. I will be surprised to find that it is impossible to perm my girlfriend's hair short in a short time because of the good thermal conductivity of jade.

Extended data

1, color

The white of white jade is often slightly blue, and there are few people who are extremely white and pure white, while nitrate is evenly white and pure white. After the light is on, nitrate still has a slight orange light.

2. Jade properties

One of the properties of jade is moist and greasy, like cream, while nitrate has a bright and moist feeling, but it has a naked feeling, but it has the feeling that thief light flashes in the bright and moist.

3. Fracture

This is an obvious difference. The fracture of white jade is stony, dull, serrated or serrated, while the fracture of nitrate is material, bright and shiny, and shell-shaped. Although jewelry appraisal can't be destructive, it can be observed through some accidental bumps, unpolished grinding surfaces and corners.

4. Impurities

There will be no bubbles in jadeite, but there will be bubbles in nitrate. Sometimes it is difficult to be observed because of its translucent color, and sometimes it is rare because of its good quality. Sometimes we can check from the surface. If there is trachoma, that is, there are bubbles on the surface, it can also be proved to be nitrate, because white jade does not have this characteristic, and the bubbles inside can also be checked under strong light.

5. Specific gravity

The specific gravity of jadeite is between 2.9 and 3.1,and the nitrate is about 2.5, which is lighter than nitrate.

6. sound

The voice of jade is dignified, and the voice of nitrate is crisp. In some cases, jade and nitrate can be identified by their different sounds.
