How to identify strange stones?

First, the naturalness of strange stones. Strange stones are the product of nature, which is called "natural generation" compared with man-made. It is independent of human will and action. What people can do about it is to "discover". It is different from all artificial skills and is a masterpiece of nature. Due to years of natural exposure or infiltration of sediment into water and soil, a layer of "skin" has formed on the surface of the stone. If you are not allowed to see the "skin", you have been told that it is unnatural. Identifying this layer of "skin" depends on experience and eyesight.

Second, the rarity of strange stones. The strange stone is unique because it is rare, rare and unusual. In terms of quality, shape, color and grain, strange stones are in the minority. To what extent? Rare. Of course, the existence of things is relative, not comparative. Who can make such a "statement"? It should be said that it is an insider. From the point of view of "layman", stone bullets are unique and almost the same. However, the wonder of strange stones lies in the "tiny" difference. Erasing this difference will confuse the different worlds of strange stones and non-strange stones. On the other hand, due to people's continuous collection of stones and the improvement of aesthetic concepts based on people's discovery, whether stones are strange or not is a constantly changing aesthetic object. As for the collection point of view, if the "once strange stone" loses its rarity, but it still has collection value, it can be used as other types of stones instead of as a strange stone collection. ?

Third, the integrity and integrity of the strange stone. As long as it is naturally formed, no matter what strange shape it is, it is not a defect of the strange stone. Correspondingly, it will increase its aesthetic feeling and collection value. The defect of the strange stone lies in the acquired injury. There is no standard that can uniformly stipulate what proportion of defective stones will lose their collection value, because we should also consider the defective parts realistically and the comparison between the defective parts and the collection value of stones. Of course, it's best not to be damaged, it's intact. ?

Some strange stones are grouped stones, and two, three or even more stones are combined into a group. For example, the stones in Three Friends in the Cold Year and the Chinese Zodiac. Getting some of them is incomplete. ?

Fourth, the ornamental value of strange stones. At the core, the collection value of strange stones is closely related to its appreciation value, which is in direct proportion. If the ornamental value of strange stones is great, the collection value is also great; The ornamental value of strange stones determines their collection value. The ornamental value of strange stones is expressed in the form of its quality, shape, color, pattern and trend. People can taste its strangeness, cleverness, strangeness, beauty and rhyme, so as to obtain the aesthetic experience of playing with stones and enjoy the beauty, thus establishing the collection value of strange stones. There is a strong individual difference in the taste of strange stones, which is the difference in the collection value of strange stones, which is explained by the aesthetic concept of strange stones. ?

Five, the volume and hardness of strange stones. As a collection of strange stones, although it has personal preferences, it is different from mountain peaks, excluding those strange stones that can only exist in nature. Therefore, as a collection of strange stones, we should first be satisfied with nature as an independent individual existence form, and we should not lose the "strange" characteristics because of environmental changes. Usually, the collection of strange stones should choose a moderate volume suitable for personal collection conditions. ?

As a strange stone, hardness is an index that must be investigated in the collection of strange stones. The hardness of strange stone is determined by its quality, which determines its ability to resist external scraping, pressure and grinding, and is directly related to the preservation value of strange stone collection. If the hardness of the stone is high, then the stone has high density, good texture and great ornamental value. The high hardness is summed up as a word "hard". The strange stone is hard, giving people a delicate, moist and smooth texture. Hardness is a geological concept with indexes ranging from one to ten. The higher the grade, the greater the hardness. As a strange stone collection, the starting point of hardness should be 4 degrees (with fluorite as the reference system). As for the above, it is the basic element of the strange stone collection. ?

Sixth, the humanistic factors of the collection of strange stones. Like many collections have this added value, the collection of strange stones depends on the original collectors or users, and the collection of strange stones can not be separated from the basic rules of this collection. A strange stone will have different added value in different degrees and contents due to different collectors. Of course, this needs to be recorded accordingly. You can't "attach" to the strange stone itself. Therefore, it will be very difficult to investigate the hidden stones in the past. In contemporary times, photography and publishing provide historical help for the future identification of the humanistic value condensed in the Collection of Strange Stones.
