How to choose Nanhong rough stone

Purchase of Southern Red Agate Raw Stone

1. What is the color of this raw agate stone? What you like is the most important. Based on the hobbies of most collectors, I will tell you about the current market value. The highest is persimmon red, then rose red, and then cherry red. Of course, cherry is only recently released, so many friends may not have heard of it! How to identify red cherries? The most important thing is that they are relatively transparent, which is what we call joint materials here (Liangshan, Sichuan). Of course, they are also available in Baoshan, but I dare not deny that they are not available in other places! The essence of this article is to see if there are any flaws, which simply means black spots or other colors. Some materials are matched, such as persimmon red and rose red, etc. As for the ones that are valuable, you can go Baidu it, I won’t be wordy here!

2. Look at the size and shape. This is very simple. In other words, what do you want to buy this stone for? If it is to make carvings, it must be in good shape. Of course, the same is true for making beads. Otherwise, no matter how big or good it is, The stone is also in vain (friends, don’t underestimate the price of Nanhong, which is made of good materials, and is rapidly increasing in value). So before buying rough stones, think about what you probably need. Don't buy them blindly. If you buy them all with large materials, it doesn't matter. At most, it is just a waste of materials. If you buy small materials, they will be wasted. When things are made from aniseed, the cost of making things will increase several times. Who of you can accept it? Try not to buy it before you understand it. People who buy stones are used to gamble. There are experienced people buying materials everywhere every day. The chance of making money is the same. But friends who don’t understand, you are one of the friends who lose money. See Everyone here knows what a professional needs for theater equipment. Let me explain it. I am afraid that some friends will not understand. It means buying a vernier caliper (for measuring sizes).

3. Looking at the cracks in the stone is a technical job. Don’t say it is simple. At least until now, among so many agate friends, no one can guarantee anything? It is recommended that friends who like Nanhong prepare a strong light flashlight. The function of this is not omnipotent, but it is absolutely impossible to buy rough stones without this thing (normal currency and bead materials do not need to be used). This thing is as useful as possible. If the inspection is cracked, some thin-skinned Nanhong can be photographed directly, but the thick-skinned ones are useless (who will ask you to peel the rough stone until it can be seen with a flashlight, at least I haven't seen it yet) ). Another way is, for example, if the outside is persimmon red and the color is very good, but when the back is illuminated and you see white light, is this stone still a good stone? Let me tell you clearly that no, there is white material or crystal behind it. If it is crystal, it is fine. If it is white material, it will be used as garbage and you have to throw it into the trash can yourself! (As for this point, this article is really too profound. My cultural level is not that high, so I can only write it here. Friends who need consultation can contact me).

4. Check the weight, that is, use stones of similar size for comparison. For example, agate of similar size is 200 grams, and one with a slightly opened mouth is only 160 grams. No matter how good the color is, this one is still the same. It is recommended that you don’t buy it. There are some good ingredients available, but the chance of getting them is only about 10. So friends who like Nanhong should prepare an electronic scale accurate to 0.1 grams! (It’s more esoteric and I don’t understand Q.) If the size is uncertain, use it with the second tool! You need to learn how to calculate the circumference of this specific item. You may think it’s not so important. When you encounter a stone worth over 100,000 and is taken by someone else for 30,000, you will regret not learning this at that time (if you understand) This thing, the 70,000 yuan that changes hands is yours. I think rich people still care about the business that earns 70,000 yuan in these few minutes! My education level is 3 years of primary school, and counting this, it is still my son who has a 6-year education. Lai Xin taught me! (If you don’t know how, you can ask me first and I can calculate the circumference and volume)!

5. Pay attention to the operation, especially when you want to change the small opening into a large opening. , Nanhong usually has a layer of persimmon red inside the skin. You should make good use of this layer. Most of the inside is variegated. When opening, try to keep it for carving, and try to keep it from revealing the background color. If the background color is exposed, it may be possible. Even if it is garbage, you still have to go to the trash can in person. At this point, have you noticed a problem? Since the color outside is good, you should pay attention to the shallowness and depth of the opening when buying materials. I will not tell you this secret, but I understand. There is no need to engage in this business, otherwise the chance of losing money is too high! I declare that I will not harm others!

6. Understand how agate is produced (meaning the common materials) What will happen inside?), I can’t explain this thing in a sentence or two. You have to slowly practice it and watch it to understand. Only when you really understand this will you reduce the risk of gambling, so take your time and don’t rush. ! Generally speaking, they are not all the same. No matter what others say, no matter how powerful they are, don’t have any illusions. Of course, it’s not that complicated to buy ordinary materials!
