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 it is very attractive because it is buried deep in the earth's surface and its output is limited, combined with the carving art and jade culture in China. If the water planted is good and of high quality, it will be more valuable. 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".
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. (There are also many people who confuse the words Cui Mo and Mo Yu. Black jade is a kind of nephrite with deep color. ). A friend often asks if a lot of ink sold outside is ink, blue water or oily green. How can we tell if it is Cui Mo? A friend often asks what clear water, green water and blue water are, and answers them here: clear water, green water and blue water, in plain English, are good water, with bright and not gloomy background, blue or green, and belong to oil-green jadeite. In the internal mineral content of jadeite, the iron content is gradually increasing, so jadeite has a blue background color. If the water is well planted, such as fine texture, high transparency and no gray background, it is called clear water, green water, clear water or lake green. If more iron is added, the background color of jadeite will be gray and oily, which is what we usually call ordinary oily green. If the iron content is increased a little, the content of omphacite in it will become higher, and it will become oil green similar to omphacite, with slightly different physical characteristics and lower hardness, which is on the edge of jadeite in a narrow sense. If the proportion of omphacite in the oil green of omphacite is high, it is the dark green of omphacite jadeite, with good water head, high transparency, green transparency and lower hardness than jadeite. More Cui Mo in the market is another kind of "pyroxene jadeite", which does not belong to the narrow sense of jadeite, because the composition of jadeite is less than 80%, and its physical characteristics are obviously different: it is dry, its transparency is worse than that of omphacite jadeite, its hardness is higher, and some of it is even higher than that of jadeite, and its refractive index is higher than that of jadeite. There is also jet, but it is not jet. Both reflected light and projected light are black. I don't know if I made it clear.
In a word, there are actually several kinds of "Cui Mo" on the market, including green glow petroleum blue, omphacite black jade, glow graphite jade and jet jade. Of course, there are also ordinary oil blue or blue water with darker colors and thicker clothes to imitate ink marks. The best way to distinguish Cui Mo from the imitations appearing in the market is to go to the appraisal institute, hand over the problem to experts, and analyze it by using the characteristics of relative density, refractive index and infrared spectrum, because it is impossible for naked eyes to judge the internal mineral composition. Of course, the naked eye can distinguish several characteristics:
1, color: reflected light is dark green or dark green, and projected light is green or dark green.
2. Look at transparency and structure: fine texture, dense particles and good transparency.
