Is to drop a drop of water on jade. If it does not disperse in the form of dew for a long time, it is a real jade, and if the water drops disappear soon, it is a fake.
Other simple methods to identify jade are as follows:
1. Touch method:
If it is real jade, it feels cold and lubricated by hand.
2. Inspection method:
If the jade is placed in a bright place such as sunshine and light, it is true jade if the color is transparent and evenly distributed.
3. Tongue licking method:
Real jade is astringent when licked on the tip of the tongue, but fake jade is not astringent. Finally, if possible, use a magnifying glass to see if there are cracks. It is the first-class jade without cracks, followed by others. The more cracks, the lower the value.

Identification of glass imitations;
There are many imitations of jade in the market, among which glass is the most common. Being able to skillfully distinguish jadeite from glass imitation is undoubtedly very helpful for the purchase of jadeite. Generally speaking, they can be distinguished from each other in the following aspects:
1. The hardness of glass is lower than that of Hetian jade and jadeite, which can be distinguished by scratching each other and looking at scratches. In addition, there are bubbles in glass products, which can also be identified by observing whether there are traces of bubbles on the surface and inside.
2. The brittleness of glass is relatively large, far less than the toughness of jadeite and hetian jade, so obvious fractures can often be seen during processing, and the fractures are neat and crisp. In addition, it can also be observed whether the fracture surface is glass luster.
3. Observe whether there are molding marks on the surface. Most glass products are molded, so the edge line is smooth and there will be traces of cooling molding on the surface.
4. Glass has strong thermal conductivity, while Hetian jade has high thermal stability and relatively constant temperature. When affected by the external temperature, the temperature difference will not change too much, while glass is different, which is greatly affected by the external temperature, and it cools and heats up quickly. You can feel the temperature difference by touching it with your hand.
5. Glass has low specific gravity and low density. Under the same volume, glass products will be much lighter, or you can hold them in your hand and distinguish them by weighing them. Hetian jade will feel "falling" when it is held in your hand.
