Five factors that determine the price of jadeite: the finer the texture, the higher the price.
1. Color determines the price of jadeite.
Color is the most important factor in evaluating jadeite. In the case of equal water, species and land, the highest value is green jade. The more green, the higher the value, followed by red and lotus root starch.
The bigger the jadeite, the better, with emerald green as the best, because green can be said to be the life of jadeite, and people often describe it as "green enough to squeeze water", "green enough to drip" and "green like Hollyleaf's ten sons after the storm".
2. Transparency determines the price of jadeite.
What is the most important criterion to determine the value of jadeite? It is transparent.
Why is it not green but transparency that determines the value of jadeite? This is because jadeite without green and high transparency also has high collection value, while jadeite without transparency and only green has little collection value.
Therefore, it can be said that green is an important factor to determine the value of jadeite, but green enhances the value of jadeite on the basis of transparency, and the value of a jadeite cannot be judged by green alone. High transparency, even colorless, yellow, red, etc. The collection value is also high. Transparency refers to the degree of visible light transmission. Jade with the best transparency is like green glass, commonly known as "glass jade" or "water head foot".
"Head and foot" and "good water", also known as "Qiao" in jargon, mean tender texture, glittering and translucent luster, dignified and not old. Among the natural jadeites produced in Myanmar, "Laoshan Pit" jade and "Shui Pi" jade are the best, and the locals call them "abundant water".
The finer the texture, the higher the price.
Texture actually refers to the structure of jade, and the fine texture is the top grade.
The jadeite structure here refers to the crystal particle thickness, crystal shape and their combined distribution of jadeite minerals, which experts call "bottom" or "bottom". Texture includes transparency, but not just transparency.
Generally speaking, the smaller the grain size of jadeite minerals, the finer the texture of jadeite minerals, the coarser the grain size of jadeite minerals, the worse the texture of jadeite minerals, the less delicate the hand feel, the worse the polishing effect and the lower the price.
We can roughly divide the texture of jadeite into five categories, from extremely fine, coarse, coarse and coarse. Generally, good jadeite is very fine in texture. We can also analyze the price difference of jadeite raw materials and study the general law according to the quality of the ground, so that it is easy to know the influence degree of jadeite value.
The "fertile land" of high-quality jadeite refers to the "fertile land" set off by jadeite, with "lake green field", "lotus root powder field" and "white bean field" as the best; Bean Green Land and Purple Flower
Land "and" green and white land "followed closely; Lime land, taro land and excrement land are the worst.
Regarding the texture and water species of jadeite, it is reported that in June 2009, 1 1, a new grading standard for jadeite in Yunnan Province was issued. This local standard in Yunnan Province was named "Quality Grade Evaluation of Jade Jewelry", which was released after being reviewed by an expert meeting.
The new standard solves the blind spot of consumers' cognition of the value of jadeite in A goods. According to the new standard, the total score of the quality grade of jadeite (A goods) jewelry is 1000. Those with a comprehensive score below 25 1 can only be regarded as qualified products, and those with a score above 25 1 can be classified into top-grade treasures, fine products and fine products, among which those with a score above 700 can be rated as top-grade products, and each product is divided into top-grade products.
This standard solves the problem that traditional evaluation only depends on personal experience, or only a single index evaluation does not have the overall evaluation result of jewelry, which is helpful for collectors to evaluate jade texture.
4. Cleanliness affects the price
Like other precious stones, the cleanliness of jadeite directly affects its value. For jadeite, the greener the color, the finer the texture, the higher the transparency, the fewer the defects, and the higher its quality and value. High purity, also known as "good perfection", no cracks, no impurities and no other colors, and the weight should be appropriate.
Jade has two main defects: white and black. Some black defects are point-like, but also filament-like and ribbon-like, mainly black minerals, such as amphibole. White defects are mainly distributed in blocks and granules, generally called stone flowers and blisters, mainly white jadeite, minerals and feldspar minerals. When evaluating jadeite, we should study the size and distribution characteristics of defects, whether they can be eliminated, whether they have a significant impact on the quality of jadeite, and the degree of impact. After comprehensive analysis, it is necessary to determine the degree of influence of defects on the value of jadeite.
5. Cracks affect prices
A big crack in a piece of jade will greatly affect its value. The degree of influence depends on the size, depth and location of cracks. Cracks also refer to the number of internal defects in jadeite. Defects include microcracks, cracks, impurity minerals, mottled patches, etc. The less the defect content, the better the jadeite texture.
