There will be crystal water in jade, is this a bit exaggerated? The audience seemed to believe it. Deputy Director Jin took out a beautiful dark green stone from the table, showed it to everyone and said: "Let me tell you something.
Speaking of malachite, isn’t it a beautiful color? It is opaque and dark green. You see, there is a stripe pattern of different colors in the middle. This unique beauty is not found in any other gemstones, and is also not found in plastic and glass products.
reached, so there are almost no counterfeit products."
Someone in the audience raised a question: "If there are no counterfeit products, wouldn't it be unique in the world? It is said that rare things are more expensive, so it is priceless?"
"Is the price high because it cannot be counterfeited? 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 is more than 90%, and the recognition of the price is the same, because
Malachite is an alteration product of copper-containing carbon salts and is often used as an associated product of copper mines. Its hardness is 3.5-4. Malachite is not durable as a gemstone because it has low hardness and cannot maintain good luster for a long time."
As he spoke, Deputy Director Jin took out a piece of pointed glass and scratched the surface hard, and a scratch appeared on the surface of malachite. Facts show that its hardness is lower than that of glass.
"Let's talk about aventurine again. It is a kind of quartzite with placer gold effect. The color varies depending on the impurity minerals it contains. Those containing chromium mica appear green, those containing blue lineite appear blue, and those containing lepidolite appear blue.
Purple." Deputy Director Jin pointed to another pile of stones of various colors on the table and said: "Inside the aventurine, the quartz particles are relatively coarse, and the flake minerals contained in it are relatively large. The flake minerals can appear in the sunlight.
A sparkling placer gold effect."
Having said this, he took a few pieces of jade to a sunny place by the window to demonstrate its luster to everyone, and then said: "Aventurine needs to be protected from direct sunlight and exposure to sunlight for a long time, because aventurine expands when exposed to heat, and its molecular volume decreases.
Increase will affect the quality of aventurine. The quality of aventurine depends on a certain humidity to maintain. Many people think that the more jade comes into contact with the human body, the better it will be if it is moistened with sweat, etc. In fact, this is a big misunderstanding. This is only limited to
A limited number of jade stones, such as flesh-white aventurine, require the help of human body temperature during the process of rebirth. However, aventurine jade comes into contact with too much sweat and is not wiped clean immediately after wearing it, which will cause erosion and damage the appearance.
The layer is damaged, affecting the original brightness."
It is said that good jade needs to be taken care of by people. The longer it is, the warmer it becomes. As the saying goes, if a person takes care of jade for three years, jade will take care of him for a lifetime. Is this wrong? There was a buzz among the people.
Deputy Director Jin sweated on his forehead, took out a tissue and wiped it and said: "Jade has a five thousand year old culture in China. When people wear jade objects for many years, they will notice changes in the jade, so this change is called
It means "people raise jade for three years", which refers to a piece of jade. After being worn for a long time, the jade jewelry comes into contact with the skin, and the sweat and fat oil metabolized on the surface of the skin nourish the jade, making the jade have a certain degree of moisture.
Slowly penetrating into the fine cracks of jade will enhance its gentleness, making the jade become gentle, shiny and spiritual, as if it is giving life. And "jade nourishes a person for life", more of it is nourishment
Knowledge of etiquette should be cultivated in character, and temperament should be cultivated. Being calm and unhurried, gentle as jade, and having high ambitions will be beneficial to your life."
The audience in the audience saw Deputy Director Jin looking confident and talking, and suddenly took off the ring on his hand and came to the stage and asked: "This is the ring my husband gave me when I got married. Is it emerald or jadeite?" Cold sweat broke out on his forehead again. Although jade and gemstones are used as raw materials for inlaying colored stones, these jade and gemstones are low-grade goods, which are quite different from those used in jewelry. It would be terrible if I got it wrong.
After he took it and took a look, Gan Dang was immediately relieved and said: "There are always people who are confused about the difference between emerald and jade, because they are both transparent and exude a charming emerald green luster. In fact, jade and emerald
They belong to two completely different categories: emerald is a gemstone, and jadeite is a jade. The ring you have is set with emerald."
The audience broke the pot and asked: "So, how much does mine cost, and what is the difference between gems and jade?"
The listener regarded himself as a treasure appraisal expert. He returned the ring to her and said: "Ask your husband about the price. Generally speaking, gemstones are made from natural single crystal minerals, which means that a gemstone is usually made from
From a single crystal, the crystal can be seen with our naked eyes. Gemstones are usually transparent. Light enters the inside of the cut gemstone. After a series of reflection and refraction, we can see the sparkle of the gemstone, such as ruby, sapphire, and granite.
Green, etc.; the surface of jade we usually see has a moist or oily texture. Since light rarely penetrates deep into the interior, we usually feel that jade is translucent. Of course, there are exceptions, and top-grade jade can also be
Almost transparent.
The brilliant colors of gemstones are set off by color, luster, transparency, refraction and cut. Because when they crystallize, they often contain inclusions, twin grains, lattice structure defects, etc., which cause interference and diffraction of light.
Scattering and other phenomena will cause some special optical effects under light. Common special optical effects include starlight effect, cat's eye effect, discoloration effect, moonlight effect, play-of-color effect, Venus effect, luminous effect, etc.
Simply put, gemstones are single crystals with extremely high hardness, usually between 8 and 10, while jade is a mixture with lower hardness, usually only between 4 and 7, or even lower."
Oh, it turns out that gems are harder and more valuable than jade. The audience seemed to suddenly realize it. More audience members took off their bracelets and came to the stage to ask him to identify whether they were gems or jade. He was so panicked that he waved his hands and shouted: "I just
Generally speaking, gemstones are more expensive than jade, and jade is often more expensive. For example, ice jadeite is more expensive than many jadeite stones. What we are talking about today is the application of jade and gemstones in the inlay process of colored stones. It is not meant for everyone to learn from.
Treasure."
During the intermission, there was a commotion on the stage. Several enthusiastic audience members rushed forward to ask for his business card and said: "Director Jin, let me appraise some old items at home some other time. I don't need you to estimate them. Just tell me whether they are."
What is it made of, be it gems, jade or stones, my whole family no longer has to worry about it."
After finally finishing the break, he lectured on the stage again: "After talking about the differences between jade and gemstones, we can turn to the topic and talk about the application of stone materials when inlaying colored stones. Most jade will change color and deteriorate due to environmental factors.
, lose their luster. But gemstones will not. Therefore, when inlaying colored stones, it is best to use gemstones or jade with high hardness and stable properties for key parts such as the eyes and windows of the soul."
