Text:

Emerald has been regarded as the spirit of heaven and earth since ancient times, which brings together the light of the sun and the moon and the beauty of mountains and rivers. For thousands of years, jade is not only a beautiful stone, but also endowed with mysterious beliefs and spiritual sustenance. Both ancient people and modern people love jade. "A gentleman does not leave his body for no reason." . Although we have a special complex about jade, we have little knowledge about it.

First, the reasons for preferring jade

Emerald has profound historical and cultural connotations and is an important part of the long-standing jade culture of the Chinese nation. Emerald has almost become the embodiment and pronoun of jade. And why do people in China love jade so much? I think it is due to the following points:

1, jadeite combines the beauty of precious jade, and high-quality jadeite is extremely rare;

2. Jade has good physical and chemical properties, with hardness of 7, which is much lower than that of diamond, but its bearing capacity is much larger than that of diamond, with good toughness and stable chemical properties;

3. China ancestors regarded green and red as symbols of happiness, prosperity and loyalty to love, and always had the custom of wearing jade to protect themselves from disasters, turn the corner, get rid of illness and prolong life;

4. High-quality jadeite is mainly produced in Myanmar and shipped to China from the beginning. China people were the first to make jewelry and jade articles, which blended into the unique traditional jade culture of the Chinese nation and became rare treasures or people's favorite handicrafts, so it can be said that China people first developed and used jade;

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

6. Jade is the embodiment of beauty, which embodies all kinds of beauty that jade has shown since ancient times, such as material beauty, personalized spiritual beauty, virtue, kindness, wisdom, justice, modesty, harmony, loyalty and sincerity. In addition, jade also highlights the beauty of color, shape, material, mystery and rarity.

7. The symbol of wealth of high-quality jadeite stone. With the continuous development of China's economy, more and more people begin to own jadeite artworks and other collectibles, and as a symbol of success, they get great spiritual enjoyment and satisfaction. Jade has the value of symbolizing identity, status and image.

Second, the appreciation of jadeite

Jade is charming, but it is not easy to appreciate her. How to evaluate the quality of a jadeite raw material is a problem that many experts study and think about. Based on the existing research results, we can analyze them 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 starch. The color directly affects the value of jadeite. Considering the quality of color, it is necessary to analyze whether the jade color is positive, whether the shade is appropriate, whether the color is cold and warm, and whether the color distribution is uniform. So-called: positive, strong, positive and flat.

Positive: refers to the range of hue, which depends on the ratio of primary color to secondary color, that is to say, it should be pure green and not mixed with other colors. For example, oil blue is often mixed with oil blue, and its value will be reduced.

Thick: refers to the depth of color. As far as emerald green is concerned, the concentration is preferably between 70% and 80%, and 90% is too strong. Too strong a color will affect transparency, and too light will not look good. It is generally believed that the color of jadeite is better in shades.

Yang: It refers to the lightness of jade color. The lightness of jade is mainly determined by the ratio of green to black or gray. The more green, the brighter the color. The more black or gray, the darker the color. Experts often use an image method to express the bright sunshine of color. For example, boxwood green, parrot green, onion heart green and pepper green all refer to the color of fresh sun. Spinach green, oil green, river green and dark green refer to dull dark green.

The fresher the jadeite, the higher its natural value.

Average: refers to the uniformity of jade color distribution. The color distribution of jadeite is generally uneven, so it is not easy to get jadeite with uniform color distribution. The green of some raw materials is banded, the color of some raw materials is blocky and some are linear. If the color of jadeite is used well and skillfully, this raw material can be used to the maximum extent and its value can be reflected to the maximum extent.

The best color: it should be pure green with a green concentration of 70%-80%, bright sunshine and uniform color distribution. This kind of high-grade jadeite habit is called the old pit species by experts.

(2) Transparency

The transparency of jadeite refers to the depth at which light can penetrate jadeite, which is called "water head" in jargon. Jadeite is a kind of rock, which is a collection of polycrystals mainly composed of jadeite minerals, most of which are translucent or even opaque. Perhaps because of this, people in China prefer jade. They like its semi-permeability and the same feeling as water.

The crystal size, arrangement and impurity content of jadeite minerals have direct influence on its transparency. General jadeite experts refer to transparency as "species" and "moisture". Good transparency means sufficient water and good planting; Poor transparency means poor planting or dry water. Some traders use vivid words to express the transparency of jadeite, such as glass species, ice species, Gan Qing species and so on.

The better the transparency of jadeite raw materials, the higher the value. Especially when evaluating middle and high-grade jadeite, the influence of transparency on the value is often higher than that of color, and jadeite with a certain color and planted can become high-grade goods. For low-grade jadeite, colored seedless species are much more expensive than colorless species, in which case color is more important than transparency.

(3) Structure

The jadeite structure we mentioned here refers to the crystal particle thickness, crystal shape and their combined distribution of jadeite minerals, which experts call "bottom" or "bottom".

Generally speaking, the smaller the crystal particles of jadeite minerals, the finer the texture of jadeite; The coarser the crystal of jadeite mineral, the worse the texture of jadeite, 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-fine-coarse-coarse-coarse. Generally, good jadeite is very fine in texture. We can also analyze the price difference of jadeite raw materials according to the quality of the ground and study the general law, so that it will be easier to know the influence degree of jadeite value.

(4) cleanliness

Like other precious stones, the evaluation of jadeite directly affects its value.

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.

Through the comprehensive analysis of the size and distribution characteristics of jade defects, and whether these factors can be eliminated, whether they will have a significant impact on the quality of jade, to determine the degree of influence of defects on the value of jade.

(5) Cutting work

The processing of jadeite products can be divided into bare products and carved products.

Bare products have high requirements for raw materials, and there can be no cracks, because cracks are easy to see. Jadeite with cracks is mostly used to make flower pieces, and cracks can be covered by carving.

Therefore, in the evaluation of nude products and flower pieces, under the same quality, nude products are more expensive than flower pieces except for particularly exquisite jade carvings.

(6) cracks

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.

Third, sentiment

Emerald has won the reputation of "the king of jade" because of its rare and luxurious characteristics. It is considered as one of the representatives of oriental civilization, the quiet charm of the East and the luxury and elegance of the West. Emerald green is deep, subtle and soft, representing a yearning, a sustenance, a satisfaction and a romantic feeling with the help of natural forces.

Emerald is a kind of stone, everyone has different views on it, and everyone's preferences are different. As the saying goes, "Gold is valuable, but jade is priceless". I think, as long as it is jade, it is enough to give you a wonderful feeling by personal feeling. We don't have to stick to the secular vision. From the heart, what you find must be the treasure jade in your heart.
