The methods to determine whether it is jade or stone include: dripping water method, glass scraping method, and observation method.

1. Water dripping method

Drop a drop of water on the surface of the jade. If it is real jade, the water droplets can condense and not disperse, but if the stone is fake jade, the water droplets will spread quickly. . Of course, this method is not 100% accurate. The water dripping on the surface will not disperse, and it is also affected by the type of jade and the polishing process.

2. Scratch the glass

Jade is a stone with a certain texture. Jade is dense and relatively hard. Just scratch it a few times on ordinary glass and you can leave clean residue. scratch, be careful not to use too much force. If the glass cannot be scratched, it may be a stone.

3. Observation method

The color of jade is naturally clear. It can be seen as transparent under the light, and when observed under a magnifying glass, no small cracks like spider webs can be seen. . If the color is in the cracks or on the surface of the jade, it may just be an ordinary stone.

How to choose jade:

First, look at the color: color is the most important factor in evaluating the quality of jade. Jade with a uniform, positive, dense and positive color is considered top grade. "Even" means uniform; "yang" means the color is bright, giving people a cheerful and non-depressed feeling; "dense" means the color is relatively deep; "positive" means there are no other colors mixed together.

The second is to look at the texture: Jade is a polycrystalline mineral formed from silicate under high temperature and pressure. 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 the jade.

The third is to look at transparency: Transparency is a physical phenomenon that complements texture. The finer the texture, the higher the transparency. If jade is as transparent as glass, the fineness of the crystals inside it can allow light to pass through without being blocked.
