At night, the rain was still heavy.

Chen Song sat cross-legged on the bed, the deafening thunder was like in his ears, the thunderstorm in the sky, the momentum of lightning and thunder shaking the earth, he couldn't settle down.

The wind swept the torrential rain like countless whips, pumping fiercely on the glass window, and the crackling rain continued to sound, making Chen Song feel a little disturbed in his thoughts, so he simply turned his head to look out the window.

The night on the mine is usually suffocatingly hot, and the coolness brought by this rainstorm should have made it easy for people to fall asleep peacefully, but it caused countless people in the mine to lose sleep, and Yang Hao also couldn't sleep because of the continuous heavy rain.

Yang Hao, who lay down early, tossed and turned on the bed, so he simply got up and paced to the window and looked out of the window.

Lightning pierced the dark night, and the dull thunder roared like a cannon, making people throb.

Yang Hao muttered worriedly, "I don't know if she's back?"

This rain continued until the morning of the second day.

The clouds in the sky seemed to have been washed away by this heavy rain, and the sky was cloudless and blue.

The bright sun shrouded the earth, Chen Song opened the window, the fresh air rushed to his face, and his face was refreshed.

After the meal, Yang Hao, who was yawning secretly and looking tired, followed Liu Yiyan and entered the room full of jade samples.

Today, both of them brought pens and notebooks, and Chen Song's pens and notebooks were stuffed to him by Yang Hao before eating.

"Master Liu, what are you going to teach us today?"

Chen Song asked after entering the room.

"Jadeite rough and wool, look at the seed, water, color, bottom, crack, how to look at the jadeite seed and water, I have taught you ......"

Liu Yiyan walked around to the back of the small table as he spoke, and said with a smile, "Today I will teach you to look at color!"

"Many kinds of beauty in nature are presented through color, and jadeite is also fascinated by its rich colors, so understanding the color of jadeite is also an important basis for evaluating the quality of jadeite!"

Liu Yan asked, "Do you know the origin of the name Jade?"

"Master, I know that it is a bird with a variety of colors, and it is used to describe this jade material as varied as the color of the jade bird. ”

Yang Hao said with a yawn.

"Yes, jadeite is the name of a bird, a bird with a red beak, green-white feathers, often fishing at the water's edge, we call it jadeite, also known as fisherman, its coat color is very beautiful, usually blue, green, red, brown and other colors, generally the feathers of the male of this bird are red, called the jade, the female feathers are green, called the emerald, the name of the red jade green emerald also comes from this, named after this bird, in order to reflect the color diversity of the jadeite and the gorgeous situation of the color!"

Liu glanced at Yang Hao, who was full of sleepiness, and shook his head.

Yang Hao saw the master looking at him, his spirit sank, and he asked with a bitter face: "Master, there are so many colors of jadeite, it is difficult to identify." ”

"The color of jadeite is indeed overwhelming, even many jadeite lovers will feel that jadeite is too mysterious, too difficult to understand, so the jade world divides the color of jadeite into seven categories, namely colorless, white, green, purple, black, yellow, red and combination colors. ”

Liu Yiyan said proudly: "In fact, to put it simply, the color of jadeite can be divided into three categories, namely primary color, secondary color and combination color!"

Yang Hao hurriedly wrote it down in his notebook.

Chen Song thought about it and wrote it down casually in his notebook.

"The primary colors are white, green, purple and black. ”

"The appearance of white jadeite is mainly because it does not have any color-causing factors in the process of formation, and its mineral composition is relatively pure, without iron or some other components, so that there will be a pure white color, that is to say, when the jadeite is basically composed of pure jadeite minerals, the color will be colorless or white, between transparent and opaque. ”

Liu glanced at Chen Song and said with a smile: "The white color of jade is the most respected color in the traditional jade culture of Huaxia for 6,000 years. ”

"Master, I see that there are many kinds of white on jadeite, and the hues are very similar, what method is generally used to distinguish them?"

Yang Hao remembered that there were many kinds of white jadeite, and couldn't help frowning and asking.

"White jadeite is classified according to its transparency, mainly according to the strength of its light transmittance, and it can also be divided into many kinds, which belongs to the problem of color difference, I will not go into details. ”

Chen Song and Yang Hao hurriedly nodded in understanding.

The color of jadeite is related to the structure of jadeite itself, and white is directly classified according to the degree of transparency, which is very suitable!

The thicker the structure of the jadeite crystal, the worse the light transmittance, the fine and dense crystal, the better the light transmittance, this different light transmission, you can directly see the difference in white color difference.

"You go and find a sample of the ice-white and the dry-white ground. ”

Liu Yan instructed Yang Hao, who was not in good spirits.

"Okay, master. ”

Yang Hao's whole body was excited, he walked quickly to the iron frame, quickly checked it, and finally took out a piece of colorless ice seed material and a milky white piece of material, and walked back.

"Master, give!"

Yang Hao handed the two pieces to Liu Yiyan.

Liu took the two pieces of material at a glance, looked at them, and nodded to Yang Hao, indicating that he was not wrong.

"The white category in the primary color is mainly divided into two types: ice white and dry white. ”

Shaking the colorless ice seed flakes, he said: "Ice white is the best in white jadeite, transparent or translucent, like our common ice and glass jadeite, this kind of jadeite is pure and flawless, crystal clear, and has a sense of ice and jade, which can symbolize pure love." ”

"The internal structure of dry white is relatively coarse, the structure is also loose, there is a certain gap between the particles, which reduces the transparency, showing a state of opacity, and the light transmittance is not very good, which belongs to the middle and low-grade jadeite. ”

The milky white piece of material on the handle also shook, and continued: "If it is a white jadeite with obvious transparency like this dry white ground, most of it has been formed in the early days. ”

Liu Yiyan put the two pieces of material in his hand on the small table and said: "The reason why jadeite is so attractive is closely related to its charming green, green symbolizes life and vitality, but the green of jadeite is ever-changing, and the hue is different, and the green of jadeite can be divided into seven categories." ”

"The first type is emerald green, requiring green to be rich, to meet the standard of positive, thick, yang and even, the typical emerald green, that is, imperial green, this color can show strong vitality, is a high-grade jadeite. ”

"The second type is yang green, also known as hibiscus green, its hue is lighter, compared to emerald green, although slightly yellowish, but the green is bright, it looks fresh and lively, and it is very suitable for young girls. ”

"The third type is bean green, which is uneven in color, sometimes yellowish or blue, and appears in patches, which is a mid-grade jadeite. ”

"The fourth category is clear water green, which is a pale green that gives people a sense of sober elegance. ”

"The fifth category is blue water and oil clear, because it contains omphacite minerals, when the green is blue, it is called blue water, just like the blue hue reflected by the water in the mountain pond, and when the green in the color is grayish and dark, it is called oil clear. ”

"The sixth type is cyan, this kind of green is uneven, different shades, gradually transitioning, green is a little black. ”

"The seventh category is dark green, also known as ink cui, the surface looks black, in fact it is dark green or dark green, a closer look will find that black with green, green with black, green under strong light transmission is green, in natural light if the black is uniform, shiny, no obvious flaws, it belongs to the very high quality of ink cui. ”

"Red jade green emerald purple is precious is a sentence that people who love jade often hang on their lips, purple represents wealth, is the symbol of Ruifu, so the unique violet variety in the jadeite, with its moist, elegant and intellectual, deeply loved by the world, especially women, it is like a girl raised in the deep boudoir, exudes a unique and elegant charm, because the color is very similar to the violet flower and got the name, it is a special variety of jadeite, the purple on the jadeite is generally not deep, the jade world according to the purple hue shade of different shades, the jadeite purple is divided into pink purple, Eggplant purple and blue-violet, pink purple usually has a finer texture and better transparency, followed by eggplant purple, while blue-purple is generally coarser in texture and often grainy, which can also be called purple bean. ”

Liu Yan paused, and after the two of them remembered, he continued: "The purple jadeite in the primary color is similar to the color of the toon tree toon bud, so the jewelry industry calls the violet color Tsubaki or spring, and it is divided into high, medium and low grades according to the color, they are divided into red spring, purple spring and blue spring, the value of red spring is higher, purple spring is slightly lower, and the price change of blue spring will have greater elasticity, although it is not the best, but it is a variety that jadeite collectors are willing to treasure. ”

As for the black category, its color is pure black, and the light basically does not appear green, and the dark tone looks masculine and full, full of justice, and is generally used to carve Zhong Kui and black-faced Bao Gong. ”

Liu finished talking about the types of primary colors in one breath.

Chen Song and Yang Hao quickly wrote it down in their notebooks.

After seeing the two stop writing, Liu Yiyan said: "The secondary color refers to the color formed by the infection of foreign minerals after the formation of jadeite, which is mainly distributed on the surface of jadeite, according to the color is mainly divided into jade color like yellow Fei and red Fei, as well as the secondary green of oil clear color, because the red Fei table is festive, Huang Fei symbolizes the brilliance and is a proud color, so it is extremely rare to plant a good jade color!"

Chen Song and Yang Hao, who quickly recorded in the notebook, both pulled the corners of their mouths slightly when they heard Liu Yiyi's words.

These rare jadeites that Liu Yiyan said could be seen everywhere in this room, and if they hadn't mined the rough stones in the mine, the two of them would probably be immune to this statement.

The entire room is filled with all kinds of different jadeite samples, from rough to finished products, and most of them belong to the top of the world, giving the illusion that all jadeite is so!

Liu Yiyan asked the two of them, "Do you know what are the combination colors on the jadeite?"
