1, weighing
Jade accounts for a large proportion. If you put it in your hand and move it up and down a few times, there will be a heavy feeling that your hand is pressed down. Maybe it's real jade. The treated jade will be a light feeling in your hand, and there will be no heavy pressure. For medium-sized jadeite, this is a good identification method.
2. Look at the luster
The surface of natural jadeite has bright glass or grease luster, while the treated jadeite surface will show dull or rubber luster.
3, scratch hardness
Emerald has a high hardness. When scraping or scraping its surface with a sharp nail or knife, it will have a slippery feeling and will not leave any scratches. However, the treated jadeite will leave obvious scratches on its surface because its structure has been destroyed.
4. Listen to the sound
Hang the jade with a rope, and then tap it gently with a glass rod, and the natural jade will make a crisp and pleasant sound; The sound of dealing with knocking jade is very dull.
Step 5 touch your hand
Natural jadeite can transfer heat and dissipate heat quickly, and it will feel cold in a short time if it is attached to the face or on the back of the hand. In addition, natural jadeite feels delicate and smooth, while the treated jadeite surface will have a rough feeling.

Colored jadeite, green is unnatural, often with yellow or blue tones; The color is uneven.
