What is the influence of common defects of South Red Agate on the collection value?

What are the effects of common defects of South Red Agate on the collection value? South red agate is naturally cracked, and there are many other flaws besides cracks. These flaws are not entirely bad, and sometimes clever carving can also increase its scientific and technological value. For the influence of several common defects of South Red Agate on the collection value, let's make a concrete analysis.

Cracks: The number and depth of south red cracks will affect the value of south red agate. If there are more and deeper cracks, the collection value of Nanhong will be greatly reduced; However, if the cracks are few and not deep, it is also good to dig them out or use them under the ingenious design of the sculptor, which has little influence on their value and sometimes can increase their appreciation value.

Impurities: South red agate has environmental impact, sometimes accompanied by black spot impurities. The collection value of Nanhong with this impurity will become lower. But only one or two points, under the design of exquisite sculptors, will play the role of finishing touch, but the impact is not great.

Waterline: Natural south red agate is more common, and a few people regard it as a flaw in south red. Many people think that the texture of south red agate with waterline will be more delicate and dense, and the reverse waterline is a good proof. The value of waterline to the collection of South Red Agate cannot be generalized.

Cotton: Like Hetian jade, the defects of South Red Agate are in the state of cotton, and some of them are foggy. If a piece of south red cotton is widely distributed and deeply buried, it will become one of the factors affecting the value of south red agate. But if it is a small part and very concentrated, it can be avoided under the skillful hands of sculptors.
