Beginner's guide, an experienced person tells you how to choose jadeite rough stones

There are always new friends in the industry who come to ask questions about gambling on stones, what to pay attention to, how to increase the probability of making a profit, etc. Gambling on stones not only depends on luck, but also requires scientific methods and practical experience in identifying jade to minimize risks. To sum up, today I will explain to the novices who want to get started how to choose the gambling stones.

1. Rub a small window on the large jade raw material, and you can see green everywhere. But think about it, if there is so much green, why not cut off a large piece so that we can see it clearly and give you a good price! It is best not to buy such jade materials, or bargain at the standard of brick materials.

2. Some jade raw materials have pickaxe marks, fractures or cuts on them. When illuminated by light, they appear lovely green, but they are not polished. Such jade materials must have too many cracks, poor water quality, irregular green color or black content in the green color. Don’t dare to polish because all the flaws will be exposed once polishing? Encounter this situation. You can point out the parts and ask him to polish them before making an offer.

3. Jade materials, especially high-grade jade materials, leave many traces of grinding, digging and rubbing when the owners are looking for green on the jade materials before they enter our border.

These traces are all areas without green, and are cleverly camouflaged with sand and glue of the same color as copper. If there are traces of artificial bumps and depressions all over a piece of jade, you should pay as much as the green you see (the value of this green after it is made into a finished product). High-end jade materials will most likely show traces of artificial polishing.

4. The cut or a large area of ​​jadeite that is all green is called full green. You must observe such a piece of green carefully. There is a saying among the people: "We are not afraid of a line, but a large area" (referring to green). This piece of green is often caused by cutting along the direction of the green, that is, parallel to the direction of the green.

In fact, the thickness of the green is only a thin layer. Researchers believe that some high-end jade materials contain high-quality emerald green. If they cut them with a knife and the condition is not good, they will just glue them together and sell them intact.

At this time, the buyer should carefully observe each piece of jade he wants to buy. If he finds any suspicious points, he can use a knife to scratch the jade to find the bonding line. He can also use the warm water method mentioned above to test. If there are bubbles overflowing on the bonding line, then this piece of jade must have been bonded.

But those jade materials in hot water. If there are only some static air bubbles adhering to the surface, this is not the case. This is because the air is brought in when the jade is placed in hot water.

5. If a piece of jade has been cut off, it is called an opening. At this time, you must look at the piece of jade that has been cut off. You must look at the extension of the green on the entire piece of jade from the seam between the two pieces of jade. Sometimes when you buy jade, the door has been opened, but the opened piece is missing.

This may indicate that there are large chunks of green on small jade pieces, while the green becomes less on large pieces. Experienced people can see that there is little chance of green entering large jade pieces and will not pay a high price. The main reason why jadeite is difficult to identify the quality is that it has a thick skin, and the openings and polished edges cannot fully represent the quality of the entire piece of jade.

The selection of jade rough materials is an investment project, and the risks are generally relatively high. If a novice wants to gamble on jade, the main thing is not to be impulsive, but to watch and learn more, be rational, stick to principles, accumulate experience, and make detailed analysis and judgments. The most important thing is not to rely on luck to get rich overnight.
