The original name of this stone is Cui Mo. In the case of opacity, the surface looks black; Light transmission shows green.
The ink is black and the jade is green. Cui Mo refers to black jadeite with green in black, not jet, black agate and black diamond. They are different jade materials. Not many people know about jet, and there are few products on the market. In fact, for 500 to 600 years, jade has become the crown of jade in Chinese jade culture. In addition to the crystal clear texture, it is more important to win people's love with its rich and magnificent colors. Its main colors are red jade, green jade and violet, and the others are white and black. The white one is called Bai Ganyu, and the black one is called Mo Yu. White-dried emerald is a very common emerald, because it is colorless, while true ink emerald is rare and precious.
Characterized in that:
1, color: dark green or dark when observed by reflected light.
2. Look at transparency and structure: the particles are closely arranged, with good texture and high transparency.
3, look at the color distribution: black is uniform, black is shiny.
4. Look at the composition: aluminosilicate is the main component of Cui Mo, which can completely transmit light, while Mo Yu Can can't completely transmit light.
5, the color is black but not ink, and the feeling of gray tone meets the requirements of top ink.
In Cui Mo, the academic terminology in mineralogy is called "omphacite jadeite" or "omphacite jadeite". The omphacite jadeite or omphacite jadeite is basically a single mineral composed of more than 90% omphacite. Its color is dark green with high transparency, and it is commonly known as Cui Mo in business. It has glass luster, fibrous microcrystalline structure and Mohs hardness of 7. The relative density and refractive index are 3.34 ~ 3.44 and 1.667 ~ 1.670, respectively, which are slightly higher than those of jadeite. It is inert under ultraviolet fluorescence and black under Charles filter. The results of microscope observation and electron probe analysis show that its composition is omphacite. The infrared spectrum and Raman spectrum characteristics are also consistent with the spectral characteristics of omphacite. Using the characteristics of relative density, refractive index and infrared spectrum, it is easy to make omphacite.
? Cui Mo is a new term in jadeite, which has only become popular in recent years. Many people are not familiar with the term Cui Mo, but they are very curious about it. In fact, it is not a high-grade jade, but because it is buried deep in the surface, its output is scarce and its mining is limited. So far, Cui Mo's share in the jade market is less than 2%. Coupled with its unique hidden color characteristics, and China's carving art and jade culture, it is very attractive. If it is a kind of water, it is of good quality and high quality.
The magnetic field is strong because it is close to the center of the earth. Feng Shui masters agree that Cui Mo has the functions of exorcising evil spirits, resisting viruses and driving away wild animals, and also has a magnetic field to attract wealth. The color varies from dark green to dark green, which is black under ordinary sunlight or reflected light, green or dark green under transmitted light, with heavy color, fine texture and dense particles. Burmese people call it "the shadow of lovers".
Cui Mo is fine in texture, black and shiny in ordinary sunlight, and strong green in complete light transmission. According to Mr. Wang Ruimin, an industry expert? It is reported that the price of raw materials in Cui Mo has risen eight times in ten years, reaching 10 times. Jet is not jet, jet belongs to nephrite. Cui Mo is jadeite, and its chemical composition is aluminosilicate, which can completely transmit light; Black jade contains too much iron and chromium, so it cannot transmit light completely.
The biggest feature of Cui Mo is that it looks completely different in color under reflected light and transmitted light, which is mysterious and attractive. This is also one of the reasons why Cui Mo has swept the market in these short years-the hidden color function.
Cui Mo is a kind of jadeite, except for its different colors, its other characteristics are almost the same as those of other jadeites. Compared with other jadeites, its biggest feature is that it looks black in appearance, but it presents attractive green in transmitted light. Many people tend to confuse Cuimo with other black jade species (black jade), because black jade is also black in appearance, which is very similar to Cui Mo. Black jade similar in color to Cui Mo includes common black Hetian jade, black obsidian, black lantian jade, black agate and black jade.
Actually, jet and jet are two completely different concepts. The jet belongs to jadeite, and the proportion of jadeite is 3.34 g/cm3, which is larger than other common jet. The refractive index of Cui Mo is 1.666, which is also higher than other common black jade. Cui Mo's hardness is between 6 and 7. Except black agate, the hardness of Cui Mo is higher than other common black jade. The most direct way to distinguish Cui Mo from other jet (except jet) is to irradiate it with transmitted light. Cui Mo and Mo Yu are both black in appearance, but they are completely different in transmitted light. Under the transmitted light, Cui Mo is green, while black jade (except black jade) shows a lighter black tone. The jet is also green under the transmitted light, but the hardness of jet is greater than jet, and the luster of jet is stronger than jet. In addition, from the reflection surface, Cui Mo can see the unique emerald, while other jet can't see the emerald, which is one of the ways that Cui Mo is different from other jet.
Cui Mo's identification method:
Cui Mo is a rare variety of jadeite, and it is gradually loved by more and more people because of its bicolor. Its solemn and mysterious temperament is one of the first choices of many people. When choosing Cui Mo, the most important thing is to master eight aspects, namely, color, purity, hardness, concealment, variety, workmanship, weight and blue.
1. color: the color of ink should be observed under natural light, the surface light should be black, and the water should be green.
2. Cleanliness: Observe the cleanliness of Cui Mo, which should be carried out under strong light, and there should be no impurity white cotton inside. And the water head is good, and it can be completely transparent in one centimeter.
3. Hardness: The polished surface of Cui Mo requires compact structure, high hardness and strong glass luster.
4. Concealment: Pay attention to the matte surface. Generally, you can hide a lot of white cotton or impurities, so you need to observe it carefully.
5. Species: To see the texture of Cui Mo species, the most important thing is to see the degree of waxy structure, which has a sticky feeling and fluorescence reflection when side light enters.
6. Workmanship: Generally speaking, Cui Mo's workmanship is complicated, so the more naked Cui Mo is, the better, except for people wearing flowery clothes, because these materials require high quality and relatively perfect clarity.
7. Weight: The bigger the ink, the thicker the better.
8. Blue: If the matte surface is not black enough and the light transmission color is not green enough, it can only belong to the blue water series, but it is also good for the elders to stick the matte. If it feels very light and the quality is not very good, it belongs to the unsightly type.
