The color of the jadeite is like a starry star. Its beautiful and luxurious attracts countless people who love jade in the world. It is red, green and green, more expensive than beauty, beautiful and beautiful. In many colors, it is mainly red, green and purple. They are all high-grade colors in jade, especially green is the most beautiful and precious. Therefore, the word "green" is almost synonymous with jade. The depth, richness, transparency, and flawlessness of the emerald green is often the most direct factor in judging the merits of a jade.
In the traditional color separation, people will use the green of the jade as "concentrate", "yang", "fute", "positive", "and", and vice versa, "light", "yin", "old", " Evil "," "flower" is the next. The so-called "concentrate" means that the color of the jadeite is dark green and green without black, while the green is lighter, it is "light". "Yang" means that the color should be bright and bright, and it looks like the eyes are bright, while the dark and not bright is called "yin". "Qiao" means that the green of the jadeite is crystal clear and cute, and vice versa. "Positive", the color should be pure, without other variegated colors, such as with variegated colors, it will appear "evil". "Harmony", the green color should be uniform. If the green distribution is different, or it is a silk strip, it is called "flower".
Because of the different greens of jadeite, in order to distinguish these green jade, the different emerald greens in the jewelry industry are the most imaged and most appropriate names. In addition to distinguishing the jadeite varieties from these names, we can see more. The cultural nature of the emerald.
There are four kinds of top grades in the emerald green: sapphire green, deep green, without any yellow, good transparency, elegant and solemn. Because it is emerald-colored, it is also called "emerald"; glass green means bright green as glass is clear and transparent, bright and bright, good transparency; green seedlings, slightly yellow in green, good transparency, color Lively and energetic, because of its green color, it has the name of "green onion" and "yellow green"; bright green, mostly refers to the medium-dark green without any yellow and blue, pure The transparency is high, beautiful and generous, and some places are called "green". These four are the most expensive, especially the precious green. Others such as Zhongpin's Yangqiao Green, Budgerigar Green, Spinach Green, Shallow Green, Light Green, Bean Green, Loofah Green, as for green, melon green, plum green, gray green, blue green, oil green, wood green Then wait for it
The green of the emerald reflects the fascinating charm of jade, which is a very important factor in the price of jade. What is more amazing is that these greens have different shapes, such as strips of green, varying sizes and mutual The unconnected block-like mass is green, the silk-like filaments are green, and the other is silk green, even green, and greenish, which makes the emerald green more unpredictable. In addition, experts often look for the law of green change according to the direction of green's general accumulation, that is, the direction of green, so as to correctly judge the depth and thickness of green.
The color of jade is not pure, it is presented through the texture of jade. The first is its transparency. Transparency is the main technical basis for the identification of gems and jade. The transparency of jadeite, in the jewelry industry, is also commonly known as "head" or "water". Those with high transparency are often said to be water heads, good water heads and long water heads. The higher the transparency, the better. Usually, the method of testing the jade head is that if the light can pass through the jade material to a depth of 3 mm, it is a water split. If the jadeite can reach the dichotomous water, it can be regarded as the superior quality.
According to the difference of the water head, those jadeites that are full of water, transparent or translucent are called "old species". The old species, the color is bright, the color and the bottom are integrated, the texture is fine and compact, and the hardness, density and refractive index are both high. Those that are opaque, dry, porcelain, less watery, less shiny, and of poor quality are called "new species." Although the new species will also have a fresh color, but because of the poor water head, it looks dull and dry. There is also a kind of "new and old species" between new and old species.
Factors affecting the color of jade, as well as the bottom. The bottom sheet can also be called the ground and the ground. It refers to the dryness of the jade texture. It can also be said that the land is green without green, and the green is a colored land. The color of the earth does not have certain shape characteristics, and it often appears as colorless, white, gray, ochre, and light green.
The texture of the emerald is determined by the fineness of its structure, the head and the amount of impurities and splitting. According to its color, head and clarity to describe the name of the earth as many as dozens. For example, glass, egg white, clear water, ice, purple water, gray water, no green, incense, earth, lake green, oil green, blue and white, water, white, white sand, Fine white, gray sand, lime, rough white, shit, and water.
Commonly, such as glass, the structure is fine, the head is full, the green is even, and it is translucent, such as glass; while the egg white is white, like egg white, the head is translucent, also known as sputum. Clear water means that the ground is colorless or even in color, and the water is sufficient, just like ice, so it is also called "ice land". Others such as oil green, glutinous rice, dry land, shit, etc., the head and clarity are deteriorating, and the quality is the same.
The land is an important basis for determining the pros and cons of jade. It is the first intuitive feeling to select and identify jade. All collectors must clear their ins and outs. The land is called "species" in the Hong Kong and Taiwan regions.
Between the emerald's land and the emerald, there is also a mutual printing layer, known as "Impression." The reflection plays a very important role in the color of the jade. A good picture will set the green color to be soft and soft, and the ground will be reflected and melted; otherwise, the green color and the earth will be tough, raw, and have a sense of rigidity. Therefore, the good or bad of the reflection directly affects the softness of the color of the jade. Because of the importance of the image, some people compare it to the "spirit" of jade. This is not unreasonable.
There is also a "绺" that affects the color of the jade.绺, is a folk custom, in fact, it is a variety of cracks on the jade, there are large and small, there are fine and thick, large splitting has evil, big cockroaches, Tongtian 绺 and so on. Small splits include small broken scorpions, layered scorpions, and scorpions. Special splits are accompanied by green mites.
