The Hetian jade water line is a translucent jade in the jade. The waterline is a kind of flaw, which has a certain influence on the value of Hetian jade, but it should be analyzed according to the distribution of Hetian jade waterline. Not all waterlines have an impact on the value of Hetian jade.
The waterline is actually a pure tremolite crystal fiber column, usually running through the nephrite, which is a relatively transparent part, especially in polished carvings.
Waterline formation
The waterline is generally formed in the process of the formation of Hetian jade, which is affected by geological movements, causing the fracture of the jade ore body, and later formed a secondary crystallization in the long years.
Waterlines are generally produced in places with the highest density in jade. At the same time, the hardness at the waterline is generally higher than where there is no waterline. The water line appears in the jade material, which means that the brittleness is enhanced here, and it is easy to collapse in the engraving. It is not suitable to throw good light in the polishing, which increases the difficulty for engraving. Under normal circumstances, the sculptor will choose to avoid the waterline engraving or remove it directly along the waterline.
There are basically three types of Hetian jade water line: thin water line, thick water line, water line between the two.
Are the water lines visible to the naked eye?
Not necessarily, you have to look at it. The fine water line is generally invisible to the naked eye. It is very finely distributed in the jade. It needs to be illuminated with a strong light flashlight to be seen. The width of the thick water line is up to 1 mm, and there are sometimes staggered tremolite crystals on the thick water line. It is very common between the two, but it is generally messy.
The vast majority of the waterline is visible to the naked eye. A small part of the waterline is difficult to see with the naked eye and needs to be found under strong sidelights.
Which Hetian jade materials have water lines?
Generally speaking, there are many water lines in Qinghai, and they often cross and even form one piece. This is also one of the structural features of Qinghai. Similarly, there may be water lines in Hetian jade in Xinjiang and Russia.
Studies have shown that the waterline may exist in all nephrite minerals, the more severe the geological changes, the easier the waterline is. Therefore, the waterline is not the unique feature of Hetian jade, don't believe that the waterline is the argument of Hetian jade.
Does the waterline have a big impact on the value of Hetian jade?
The waterline is considered to be able to reduce the price of jade, the waterline will be removed or masked with craftsmanship, and some unobvious waterlines are acceptable. Most of the time, the waterline is to reduce the price of Hetian jade, but there are exceptions. If the waterline distribution is very characteristic, the natural grain pattern can be used as a finishing touch to the value of Hetian jade.
