Jadeite is a natural jade that has been formed over hundreds or even thousands of years. It is inevitable that some cockroaches will appear, but these cockroaches are natural and not intentional. If you want to observe whether the jade is smashed, we can use the flashlight to illuminate the jade, you can see if there is any jade, or you can use a magnifying glass to see if there is any flaw. What are the natural flaws in the jade? The main defects are cracks, cracks, ribs, stone, stone, and variegated.
Miscellaneous
The variegated material like the roots and the slag is the impurity formed by the natural environment during the growth of the jade. It is visible to the naked eye, but it is not a crack and is naturally formed.
Most of the jadeite is green, but in addition to green, there are large and small colors mixed in it. Small areas or point-like red, yellow, and green can make jadeite add a different style. This color is called pretty color. The small area or the point of black, gray and brown makes the jade become less beautiful and may even lower the value of the jade, such a color is called variegated.
Stone pattern
The striking feature of the stone pattern is that the structure of the adjacent parts of the emerald dislocation is uneven, like a crack, because it is formed in a complex geological environment for a long time, due to the individual misalignment caused by the extrusion. Stone grain is not a crack, it is naturally formed. The ice pattern we often see is also a kind of stone pattern.
Waterway and splitting
However, many people do not know the clefts and waterways of jade, both of which are jadeites. Waterway means that the boundaries of color change are clear. The splitting refers to the crack. In the interior of the jade, the small crack is called "绺". Outside the jade, the obvious and large one is called "crack". The two are very similar, but if they are unclear, they will also be given to everyone. Cause damage.
Then why do we distinguish the difference between the two? Because the split and the waterway are completely different concepts, and the price of the bracelet is also greatly affected. "绺" is a small crack caused by jade in the process of production, but it is usually inside the jade. "Cracking" is a crack caused by man-made in the later stage of processing, and cleft palate is also common in jade, but the waterway is natural and has no cracks.
If you have identified this jade waterway, you must first determine whether the jadeite is A cargo, B cargo, or C cargo. A goods are pure natural jade, but after some treatment. B goods are firstly rinsed with strong acid, and then infused with colorless epoxy resin, so there will be no black or yellow color blocks of natural jade, but the surface of B goods will see some under the illumination of strong light. Small pits, this is the trace of acid corrosion. C goods are dyed jade, we can see from the color of jade whether it is C goods, the general C goods are in the color of jade.
But we must also pay attention to carefully distinguish the difference between the waterway and the splitting, so that we do not take the waterway as a split and miss a good jade.
