The jade with both colors and species is good jade
They all said that "the layman looks at the color and the insider sees the species." What is the "species" of jadeite? "Species" refers to the texture, which is evaluated by the degree of the thickness of the particles, and refers to the thickness of the crystalline particles. It relates to the specific performance of specific jade jewelry in terms of beautiful properties (gloss), durability (hardness, toughness), and scarce properties. However, there are many words used in jadeite. There is no exact fixed classification. Most of them are descriptive vocabulary used by experts. As their personal preferences are different, there will be more or less discrepancies. In general, the smaller the crystalline particles, the finer the texture, the older the species; conversely, the larger the crystalline particles, the worse the species. A good kind of jade, the particles should not only be fine but also uniform, the particle size is uniform, can not be large or small, so when the light shines into the jade, the absorption less reflection will make the jade more lustrous, just like the reason why the diamond is so brilliant Because its particles are very very fine, the finer the jade particles, the older the species. The most direct influence of the quality of the jade is the delicate degree and transparency of the jade. The thickness of the mineral directly affects the transparency and smoothness of the jade. There is also a rough classification, which is glass, ice, oil, bean, green, white, and dry. The best variety is the "glass type". Crystal particles are not seen at all. Like amorphous glass, it is completely transparent. There is live light inside the jade. However, most of the glass species are colorless, even if it is lighter green, if there are few green and rare glass species, it can often reach the "high price." "Ice species", basically no crystalline particles, translucent, and no living light. What is color and no species? Although some emerald colors are bright and beautiful, but the transparency is poor, this jade is called colorless and the value is not high. Because the transparency is poor, when the light hits the surface, it can't penetrate. It can only be reflected from the surface, and its green color can't be released through the light, making people feel that the color of this jade is very rigid. A good jade must be a good color. Therefore, in the private sector, “species†and “water†are often not separated, and “water head†is also one of the common sayings of jade texture in the industry, because there is a certain relationship between species and water head. Generally speaking, if the jade is well planted, the jade's head is good, but the two are not absolutely related. For example, although some jadeite species are very good, the crystal particles inside the jadeite are very fine, but the combination between the crystal and the crystal inside the jadeite is not good, and the cementation between the crystal and the crystal is not tight, which affects the transmission of light, so the transparency of the entire jadeite It will be worse, the jade's head is not good. On the contrary, there is also a kind of jadeite. Although the crystal particles are coarse, the crystals inside the jadeite have good coupling and high density, which is conducive to the transmission of light. Therefore, the jade has good light transmission and the water head will be good. Of course, the current kind of difference and kind of cultivation are a relative statement. The quality of the species is only one of the criteria for judging the value of jade. The difference in species will cause a huge gap in the value of jade, but the difference is not absolute. A good jadeite must be a comprehensive assessment of species, water, color, work, and sputum. Polyether Polyols For Polymeric Polyols
