There will be crystal water in jade, which is a bit exaggerated? The audience seems to believe but not believe. Deputy Director Jin took out a beautiful dark green stone from the table and showed it to everyone, saying, "Let me tell you about malachite. This color is beautiful? It is an opaque dark green. Look, there is a strip pattern in the middle with different colors and light. This unique beauty is not available to any other gems, and it cannot be achieved by plastics and glass products, so there are almost no counterfeits."

Someone in the audience asked a strange question: "Will there be no counterfeit products in the world? It is said that rare things are expensive. So, their price is endless?"

"Is it high if you can't counterfeit? This is not necessarily the case. Buddha said that there are no two identical flowers in the world, but in people's minds, the similarity of flowers exceeds 90%, and the price recognition is the same. Since malachite is an alteration product containing copper carbon salts, it is often used as a companion product of copper ore. Its hardness is 3.5-4. Malachite is not durable and has low hardness and cannot maintain a good luster for a long time." As he said that, Deputy Director Jin took out a piece of pointed glass and scratched it hard on its surface. A scratch appeared on the surface of the malachite. It was shown that its hardness was lower than that of glass.

"Let's talk about Dongling jade, it is a kind of quartzite with a sand-gold effect. The color varies depending on the impurity minerals contained in it. The chromium-containing mica is green, the blue-line stone is blue, and the lithium-containing mica is purple." Deputy Director Jin pointed to another pile of various stones on the table and said: "The quartz particles inside the Dongling stone are relatively coarse, and the flake minerals contained in it are relatively large. In the sunlight, the flake minerals can show a glittering sand-gold effect."

Speaking of this, he took a few pieces of jade to the sunny place by the window to demonstrate its luster and said: "Dongling stone needs to be kept from being direct sunlight and exposed for a long time, because when Dongling jade expands when it encounters heat, the increase in molecular volume will affect the quality of Dongling jade. The quality of Dongling jade depends on a certain humidity to maintain. Many people think that the more jade comes into contact with the human body, the better the warmth of sweat, etc., which is actually a big misunderstanding. This is limited to a limited number of jades, such as the flesh-white Dongling jade, in the process of rebirth, requires the help of human body temperature. However, Dongling jade comes into contact with too much sweat and does not wipe it clean immediately after wearing it, it will be eroded, causing damage to the outer layer and affecting its original brightness."

It is said that good jade needs to be raised by people, and the longer the time is, the more gentle it becomes. As the saying goes, a person raises jade for three years, and jade for a lifetime. Is this view wrong? There is a buzzing sound among the crowd.

Deputy Director Jin sweated on his forehead, took out a tissue and wiped it and said, "Jade has a 5,000-year-old ancient culture in our China. When people wear jade objects for many years, they will find that the jade has changed. Therefore, this transformation is called "three years for people to raise jade", which refers to a piece of jade. After a long period of wear, the jade jewelry touches the skin, and the sweat and fat oil on the surface of the skin nourish the jade, making the jade have a certain humidity, and slowly penetrate into the fine cracks of the jade, which will enhance its gentleness and make the jade become more gentle and shiny, with spiritual power, as if granted to life. "Jade nourishes people for a lifetime" is a lot of raising etiquette and knowledge, character, and temperament. Calmness, warm as jade, and lofty ambitions are beneficial for a lifetime."

The audience saw Deputy Director Jin's confident look and talked freely. Suddenly, he took the ring in his hand and went to the stage and asked, "This is the ring given by my husband when I got married. Is it emerald or jade inlaid?"

Cold sweat broke out on his forehead. Although the colored stones are inlaid with jade and gems, these jade and gems are both low-end products and are of a large grade difference from those used in jewelry. If you say it wrong, it will be bad. After taking it, he immediately felt relieved and said, "There are always people who are confused about the difference between emeralds and jadeites, because they are both transparent and radiate a charming emerald luster. In fact, jade and emeralds belong to two completely different categories: emeralds belong to gems, while jadeite belongs to jadeite. The emeralds are embedded in your ring."

The audience broke the casserole and asked: "So, how much is mine? What is the difference between gems and jade?"

The audience regards himself as a treasure appraisal expert, and he returns the ring to her and said, "You ask your husband about the price. Generally speaking, gems are made of natural single crystal minerals. In other words, a gem is usually taken from a single crystal. The crystal can be seen with our naked eyes. The gems are usually transparent. The light enters the inside of the cut gem. After a series of reflections and refractions, we can see the gems' gemstones, such as rubies, sapphires, emeralds, etc.; the surface of the jade we usually see is a hydrated or oily texture. Since light rarely penetrates the inside, we usually feel that jade is translucent, and of course there are exceptions. Top jades can also be almost transparent.

The brilliant gems are colorful and are contrasted by color, luster, transparency, refraction and shaping. Because when they crystallize, they often contain inclusions, double crystal patterns, lattice structure defects, etc., causing light interference, diffraction, scattering and other phenomena. Some special optical effects will appear under light. Common special optical effects include starlight effects, cat's eye effect, color discoloration effect, moonlight effect, color effect, Venus effect, luminous effect, etc.

Simply put, gems are single crystals with extremely high hardness, generally between 8 and 10, while jade is a mixture with low hardness, usually between 4 and 7, or less."

Oh, it turns out that gems are harder and more valuable than jade. The audience seemed to have a great enlightenment. More listeners took the handpieces they wore and went to the stage to ask him to identify whether it was a gem or a jade. He was so panicked that he shook his hands and shouted: "I just said that in general, gems are higher than jade, and there are many more jades. Ice-type jade is more expensive than many jades. Today, I am talking about the application of jade and gems in the inlaying process of colored stones, not to appraise treasures for everyone."

During the intermission, the stage was in chaos. Several enthusiastic listeners rushed forward to ask for his business card and said, "Director Jin, I will identify several old items in my family one day. Don't you estimate the price. Just tell me what it is made of, gems, jade or stone, so that my whole family will no longer be worried about it."
