Water head
The emerald water head refers to the degree of transparency or hydration. There is a saying in the jade circle: the insider looks at the water and the layman looks at the color.
The water head is a problem that is easily overlooked when an outsider chooses a jade bracelet. When buying a jade bracelet, it is best to choose a jade bracelet that looks crystal clear and watery.
texture
The jade texture can be understood as the combination of the structure and transparency of jadeite. The important characteristics of high-quality jadeite are luster, warmness and fineness. These properties are closely related to the structure.
The tightness of the composition of the jadeite minerals and the size of the mineral particles are particularly important. If the particle size is small, the gap between the particles is small, the combination is dense, and the transparency is good. The appearance of the jade will be shiny and warm, and it will be observed by the naked eye. The phenomenon of jade particles is not visible, and the overall feeling is very strong.
If the particles appear to be obvious, the structure is rough or blocky, the texture is not good, and the jade with good permeability, if the inside of the eye is visible, more cotton-like objects are visible, and the quality is general.
colour
Common colors of jade color are: green, colorless, transparent, white, purple, yellow, blue, red, black, brown, gray.
The most common white, the price is cheap, the black is the ink green, and the price of the pendant is not low, the brown and gray are the second, basically will not be processed into jewelry.
The value of gray in the green is also greatly reduced. The color is bright, rich, and not black. The color distribution is usually distributed evenly, the coverage is wide, the smoothness is natural, the noise is large, and the distribution is not smooth, which greatly affects the value.
Processing technology
As the saying goes, jade is not a mess, and the excellent jade processing technology can enhance the value of jade, and it is more in line with people's aesthetics.
The jade products carved out by the machine are quite normal in terms of pure hand-carving. The medium and high-grade jade are hand-carved, and the ordinary low-grade jade is mostly machine-carved.
Clarity and ç‘•ç–µ
Clarity is an important concept in the evaluation of gem quality in gemology, because most of the flaws that degrade the clarity will have a negative impact on the aesthetics of gemstones. There is a clear jade, its value is greatly reduced, and serious cracks may even affect people's safety.
Many people like jade, because jade can be carved into a variety of different jewelry, the same quality of jade, the price of the bracelet is higher than jade, because the bracelet has more consumables.
Other standards
In the case of a bracelet alone, in general, the value of a wide flat sliver bracelet is greater than that of a round sliver bracelet, and the value of a circle bracelet is greater than an elliptical bracelet (ie, a chaise bracelet).
The value of a large circle bracelet is greater than that of a small circle. The value of a thick bracelet is greater than that of a thin strip. The value of a thick bracelet is greater than that of a thin strip.
The value of smooth surface and no collapse is greater than that of the case where the collapse is not smooth, and the sliver thickness is uniform and polished, which is also the performance of the process, which also affects the price of the bracelet.
