Hetian jade material identification skills novice must!
We have different opinions on the identification of Hetian seed material. In fact, to distinguish the authenticity of the seed material, we can start from the following aspects.
1, color
Hetian seed material is better in white. Among the four characteristics of “white, moist, fine and tough†of sheep fat white jade, “Jade White Run†ranks first. Therefore, the image used in the industry is called brown rice white, chicken bone white, and sheep fat white.
White is further divided into first-grade white, second-order white, followed by white and so on. The Qingbai jade in the Qianlong period was worth more than the value of the modern sheep fat jade.
White is good, but if it doesn't look oily, there is no moisturizing, dead white, dry white, white water, the value of such seed will not be too high.
2, texture
The texture of the Hetian seed material is determined by its internal structure. The degree of detail, transparency and luster are the three main aspects that reflect the quality of jade. it is good
The seed material is hard and fine, which is reflected in the perceptual knowledge. First, the appearance is very delicate, and the second is hard and does not eat a knife. The fine jade is generally dense and has a distinct sense of hand.
The jade is not as transparent as possible. The fine jade is often tightly structured and strong, and the effect is translucent or slightly transparent. The Hetian seed material has these high-quality conditions, while the Qinghai Baiyu Mountain material has a relatively loose texture and its transparency is high.
The jade is fine and compact, and its oiliness is strong. On the other hand, if the texture is relatively loose, its grease degree is weak, such as mountain material. Good seed material should be like fat, which should be like sheep fat, like lard. The oil is also sturdy and crisp, and the "intense of light" is very connotative.
3, the shape
The shape must be naturally formed, the surface is natural, the lines are smooth, and there is a sense of easyness in the hands of natural seeds. If the day after processing, whether it is a roller, or polished, it will destroy the seed material, then the natural beauty, the value will be reduced.
1) Pebble, potato-shaped round or ellipse, this shape of seed material is full and steady in the hand.
2) Some shapes and odd colors, like landscapes or animal heads, etc.
3) If you feel comfortable in your hand, you can play it or you can sculpt it.
4) It varies from person to person, as long as it is real, like it.
4, cleft palate
Splitting refers to all the cracks on the jade. According to the jargon, the small cracks are called 绺, the big cracks are called cracks, and they are called "cracking". Generally divided into two categories: "dead splitting" and "live splitting".
The dead cleft palate refers to the obvious splitting, and its thickness, length, and depth are different. The long and deep encounters are squatting, the two sides are shallow and the middle is deep, and the jade inside the jade.
The active cleft palate refers to a small cleft palate. There are various kinds of nails, such as nail-like seams mainly distributed on the surface, from the surface to the inside, which are scaly-like fire-damaged, and the fine-grained hair with uniform cracks in the same direction. Wait.
In general, death is good, and it is difficult to get rid of it. Generally, it is difficult to predict the occurrence of fetal cleft palate, and other cleft palate is judged. If you are not sure whether to invade the internal cleft palate, you only need to cut a plane in the plug skin, and you can see at a glance if you die and live.
Under normal circumstances, the flashlight is used to see transparency. Without transparency, the stone in the seed material is relatively large and the value is not high.
In order to grasp the quality of the identification of Hetian jade seeds, the most important thing is to get started with the real thing, more contrast, only more practice, will really appreciate the subtleties.
