Yu Ji also squeezed into the crowd and looked at the big rock under the machine.

He glanced at it and pursed his lips.

Jadeite has "thirty-six water, seventy-two beans (green), one hundred and eight blue" said, often used to explain that the change of jadeite water is very complex, varied, difficult to identify.

There is also a saying that "the layman looks at the color, and the insider looks at the seed". There is also a saying in the industry that "planting a good shade of three ugliness", which refers to the kind of jadeite that can not only make the light-colored jadeite appear crystal beautiful, but also make the uneven color appear uniform due to mutual reflection, and it can also make the jadeite with a fine texture not appear obvious.

Therefore, I am not afraid of no color, but I am afraid of no seed.

The most high-end classification of jadeite seed water in the current market is glass species, followed by ice species, water species, ice glutinous species, agate species, bean species, green species hibiscus species, etc.

The jadeite grade is also divided into five grades: first-class superb, second-class, high-grade, third-grade, middle-grade, fourth-grade, and fifth-grade.

According to the color, it can be divided into colorless: generally transparent or translucent, without colorless roots, mostly ice and glass.

White: The particles are coarse, loose in structure, and there are certain gaps between the particles, which reduces the transparency, and presents milky white or white. It is generally classified as low-grade jadeite, which is the most common and most common type of jadeite.

Green: Emerald and imperial green are the best in jadeite, followed by Zhengyang green, bean green, dark green, blue green, dark green, etc.

Purple: Purple jadeite is also called spring color or violet jadeite, purple jadeite is called red spring with reddish hue, and purple spring is called purple spring with blue hue.

The big guy who is opening the stone in front of him looks smooth on the surface, with cracks, but there is no green inside.

There are greens that are scattered everywhere, and the filaments are incoherently formed.

"Alas......"

The cutter finally completed the first knife, and he couldn't think of the green, and there was a lament all around.

The man standing next to the cutter also turned pale, obviously the buyer of the big stone.

"Do you think this stone is green?"

Seeing that Yu Ji was looking seriously, Li Mingxiang couldn't help but ask her funny.

Yu Ji shook her head, "I don't know, I feel like I should be able to." ”

Li Mingxiang waved his hand, with a look of pity, "I don't think I can't." ”

"How?"

Li Mingxiang groaned, held his chin and continued: "I suspect that this is artificially forged, you see the side that the cutter just cut out, there is no large area of green, and there are many residual filaments, and then look at the white foam next to it, as well as some broken skin next to it, those may be soft objects left after artificial excavation." ”

Seeing the little girl's somewhat puzzled face, Li Mingxiang smiled and explained, "Generally, the heart of counterfeiting is like this, take out a part of the high-grade jadeite heart, leave the skin part of the high jadeite, and then inject some substances into the incision well. The average layman can't see it, and if the insider is not experienced, nine times out of ten will be deceived. ”

Li Mingxiang's words made Yu Ji look at him with admiration, and she already had a new abacus in her mind.

The big stone over there has been cut.

Alas, there was a sound.

"It's a pity! It's not green! ”

"Yes! 30,000 yuan was wasted like this! ”

"Let's scatter, let's go, there's nothing to see!"

"Let's go, I'll take you to pick some wool."

Yu Ji followed behind Li Mingxiang, her eyes drifting around, and when she looked at it, she already had a goal in mind.

Li Mingxiang took a strong flashlight and a magnifying glass from the side and handed them to Yu Ji.

He looked carefully left and right, and after a while, he handed Yu Ji a palm-sized stone.
