Jasper is favored by many people because of its delicate color, but when we bought Jasper, we found that many jasper will have black spots on it, and we want to start but don't worry. I believe that many people will have such doubts. Can jasper with black spots be bought or not, and will be fooled. Today, Xiaobian will give you a detailed analysis.
The cause of the black spots of Jasper
To understand the black spots of Jasper, we must first understand the cause of Jasper. The main minerals in Jasper are tremolite and actinolite. The interior contains more mineral elements such as chromium, iron, calcium and aluminum. Therefore, black or green spots often appear. .
The black spots in Jasper are formed by the aggregation of iron in jade. No iron or green, most jasper will have some black spots, whether it is Russian jasper, or Manas jasper, or Canadian jasper. It can be said that black spots and dark spots are a feature of jasper and a sign of identification. As the iron oxide content increases, the color of the green also deepens.
The difference between different jasper black spots
There are black spots in all types of jasper, but the origin of jasper is different, the quality of jade is different, and the size and distribution of black spots are also different.
Let me talk about the black spots of jasper seed, the jasper seeds are very small, and the color is better. Compared with other jasper, the color of jasper seeds is heavier. Generally, jasper seeds have more black spots, which are generally point-like, and many of them have larger black spots. Because of its color characteristics, rarity and poor general quality, jasper seed products are very rare. The price of jasper seeds is not too low, but in the group that likes jasper seeds, often a good jasper seed is worth a lot of money, and it is very difficult to find.
Let's talk about Russian Bi. Obi is the main force of the market's jasper, famous for its delicate color, less black spots and less splitting. Many of Obi's old materials are beautiful in color, heavy in color and less black. But nowadays, the new material of Russia and the United States is mostly dry, the color is floating, and the new material is more black spots.
Because most of the new materials have scattered black spots, the carvings are not only treated with hollowing or surface relief, but there is almost no possibility of being cleaned. It is easier to distinguish them. In addition to the duck egg green on the market, the so-called green ice bottom is basically new.
Plus Bibi Manas jasper has a large output, large volume and relatively few black spots. Its green color is closer to the yellow color than the green color of Russian jasper. The meat density is slightly worse, the material quality is watery, but the structure is more delicate.
The biggest feature of Manas Jasper is that the green color is one by one, with a bit of a bit and a strip of pale white markings. There are black ink spots in the jade, and the ink particles are relatively large. It may be due to density and structural problems that a waxy glow appears on the exterior.
However, no matter which place of jasper has black spots, and the distribution of black spots is not absolute, it is not possible to use black spots alone as the basis for identifying the origin.
Is there a black dot that is not good?
How do we look at the black spots? No black spots are good, is there a black spot? This is not the case. Regarding the black spots, I don’t know if you have noticed that in the jasper, the jasper with black spots and black groups will often look more green!
In fact, this situation is also easy to appear in the jade, because the green color in the jade is mostly formed when the jade is formed or later by the color of the outside world! This situation is also very common in Saitama. There are also Qilian jade, Taishan jade is more obvious, and Jasper is the same reason!
It can be said that some jasper black spots with a lighter color will be less, such as duck eggs with very light colors, almost no black spots, and almost all dark colors will have black spots, such as spinach green, if you are looking for A spinach green without black spots is really too difficult.
So no black spots are good, but black spots are normal. It is not that black spots are faulty, and black spots tend to be more green in color.
How should Jasper choose?
Most of Jasper will have black spots, so how do you choose when there are black spots?
The first thing to do is to pick black spots with evenly distributed black spots and look even more comfortable. If the black spots are scattered and the other is clustered, it is good to choose black blocks when the jade phase is similar, because in the case of the same price, the other parts with black blocks are relatively pure, and The black group is often accompanied by a thick dark green. This dark green is excessively produced by green to black, and it looks very natural.
Regarding black spots, it is necessary to combine jade and color. In the case of good jade color, the less black spots, the better. Jasper is generally stuffy, so pick jasper to see that the flesh is bright and the color is not stuffy. Also look at the jade, the better the degree of lubrication, the more delicate the better.
Then if you are a perfectionist and want to find a jasper without black spots, there are also some, such as bracelets with no black spots, but the price will remain high.
We often say that there is no iron and no green, it may not be absolute, but there is a certain truth. Jade is not finished, and those just right ones add a unique charm.
