"A gentleman is unreasonable, and jade never leaves. Although jade has a special mentality, it knows very little.

Prefer jadeite

Jade has profound historical and cultural connotations, and is an important part of China's national culture with a long history. Jade has almost become synonymous with jade and jade. The embodiment of the people, why do people in this dilemma love jade the most? I think this is due to the following reasons:

Gems and jadeites American jadeite is embedded in an extremely rare and high-quality jade;

Emerald has good physical and chemical properties and hardness, far superior to low diamond, but its pressure is much greater than that of diamond, and it has good toughness and chemical stability.

China's ancestors, green and red represent happiness, prosperity and loyalty to love. Yu Pei has the custom of taking refuge for self-defense, getting rid of illness and prolonging life.

High-quality jade is produced in Myanmar and brought to China from the beginning. China people made jewelry and jade articles for the first time, and incorporated them into the unique traditional jade culture in China, making them a rare or popular art and handicraft. Therefore, it can be said that China was the first to develop and utilize jade;

5. Emerald has rich cultural connotations, which fully embodies the profound cultural heritage of China and the profoundness of Chinese civilization;

6, jade is the embodiment of beauty, it brings together the performance of ancient jade, the material is beautiful, the soul and virtue are the embodiment of beauty, love, wisdom, justice, humility, harmony and loyalty. Because of all kinds of beauty and sincere beauty, jade also highlights the beauty of color, appearance, material, mystery and scarcity;

7. High-quality jadeite stone is a symbol of wealth. With the continuous development of China's economy, more and more jadeite artworks and other collectibles are regarded as symbols of success, and more and more people begin to enjoy and satisfy with great spirit. Jade has a status symbol and a value image.

Second, appreciate the charming jade. Of course, her appreciation is not an easy thing. How to evaluate the quality of jadeite raw materials Many experts believe that the existing research results can be analyzed from the following aspects:

(1) Color:

Color is the most important factor in evaluating jadeite. The highest value of jadeite is green, followed by red and lotus root powder. The quality of the color directly affects the value of jadeite, or it is not good. This is an analysis of some specific aspects that need to be considered, whether it is the jadeite color with appropriate pre-tone color and uniform cold and warm colors. So-called: positive, strong, male, all

Positive: refers to the range of tones, according to the ratio of primary colors to intermediate colors, green and pure, rather than mixing with other colors. Like the value of oil blue? Will fall down.

Concentration: means that the concentration in the culture medium is preferably 70%? 80%, 90% dark color, emerald green, too strong. Too strong a color will affect transparency, and too light and bright will not look good. It is generally believed that the appropriate jade color has better effect.

Yang: It refers to the color of jadeite, fresh, active and bright jadeite, and the ratio of bright jadeite green to black or gray. The proportion of green is mostly bright, and black or gray is mostly dark. The images of connoisseurs are mostly shot in bright sunlight, such as boxwood green, parrot onion and green pepper, which refers to the color Xianyang. Spinach green, oil green, river green and black green refer to dark green.

The fresher the sun jadeite, the higher the value. "

Average: refers to the uniformity of jade color distribution. The color distribution of jadeite is generally uneven, and it is really not easy for jadeite with uniform color distribution. The colors of some raw materials distributed in some green areas are waves and clouds, and there are some lines. The color of jadeite, if used properly, can be used to the maximum extent and reflect its value to the maximum extent.

Color: High-grade jadeite with green and pure green concentration of 70%-80%, bright sunshine and uniform color distribution is often called Laokeng by experts.

(2) Transparency

The transparency of jadeite refers to the depth of energy passing through jadeite jargon called "head". Jadeite is a polycrystalline aggregate mainly composed of rocks and jadeite minerals, which is the most translucent or opaque. Perhaps because of this, China people prefer emeralds, such as jadeite, which is semi-permeable and impermeable.

The size, arrangement and impurity content of jadeite minerals that make up jadeite directly affect its transparency. Jade experts generally call it "competition" and "water" transparency. Good transparency or sufficient water, poor transparency or very dry water are all one kind. Some lines have vivid words to express the transparency of jadeite, such as glass species, ice species and Gan Qing species.

Jade raw materials have good transparency and high value, especially the evaluation of high-grade jade. The value of high transparency is often higher than color, and jadeite with good color can become a luxury. Among low-grade jadeites, it is more important than colorless species. In this case, polychromatic species are more important than transparency.

Structure. The jadeite structure we are talking about here refers to the combination of the shape of jadeite mineral crystals and the thickness of crystal particles that make up jadeite. Experts say that "bottom" is still "ground".

Generally speaking, the smaller the jadeite mineral crystal particles are, the finer the jadeite mineral crystals are, the worse the jadeite texture is, and the price of fine polishing effect is not low.

The texture of jadeite can be roughly divided into five categories, from extremely fine to coarse, fine to coarse to extremely coarse. Generally, a good jadeite texture is very delicate, and you can also know whether the foundation is good or bad. If you want to analyze it, you will know the difference in vibration amplitude of jadeite on the ground. Formulated a general rule, the price of jadeite raw materials will be easier.

(4)

The cleanliness of jadeite is just like the evaluation of other precious stones, which directly affects its value.

Jade is black and white. Black Spots Some banded black minerals, such as amphibole, are also successfully distributed in spots. White defects are mainly distributed in loose particles, commonly known as stone flowers and blisters, mainly white jadeite, minerals and feldspar.

Whether these factors can be deleted, whether the quality of jadeite can be comprehensively analyzed, the degree and distribution characteristics of jadeite can be determined, and the value of jadeite can be influenced by defects.

(5)

Emerald-shaped cutting can be divided into bare products and carved products.

The product has light weight, high requirements for raw materials and no cracks, because cracks are easy to see. Cracked jadeite is mainly used to make flowers and sculptures to cover up cracks. "

Evaluation of naked finished flowers, in the same quality, light and body care products are more expensive flower carving objects, of course, especially carved jade.

(6) Cracking

Crack, if a piece of jade has a big crack, it will greatly affect its value. The degree of influence depends on the size, depth and location of cracks.

mood

Jade, with its rarity and luxury, has won the reputation of "Jade King". Both the tranquility of the east and the elegance of western luxury goods are regarded as one of the representatives of eastern civilization. Green and deep, subtle and soft, represents a longing, a sustenance, a satisfaction, a natural force of romance.

Jade original stone, everyone's views are different, and everyone's preferences are different. As the saying goes, "Gold is valuable, but jade is priceless." In my opinion, as long as jade, my personal feeling, can give you a wonderful feeling, it is not enough. We don't have to stick to the secular vision. From the heart, the gem must be found in the heart. involve
